What’s The Difference: Valves – Ball, Gate, And Globe Valve?

by vemcoblogs -

Some of the most important aspects of a fluid management system are controlling, regulating, and directing the fluid. This is made possible by devices known as valves. Both domestic and industrial valves are used to direct the flow, shut access, adjust pressure and prevent back-flow in the pipes. These are especially useful when a section of the piping is undergoing repair or maintenance. Each valve however is uniquely designed to meet specific plumbing needs. As dealers of some of the best industrial water pumps in Mumbai, let us explain the difference between a Ball, Gate, and Globe Valve.

Ball valve:

A ball valve has a hollow ball in the center through which the liquid passes. As long as the hollow ball is in line with the direction of flow of the liquid, it flows with ease. But as soon as the hollow is turned perpendicular to the direction of the flow, it completely stops. Even turning the ball using a long and easy-to-use handle above by 1/4 is enough to cut off the flow and immediately create a powerful watertight seal inside. These valves are easy to use, durable, reliable, and especially useful in times of emergency. But besides turning off the flow completely, a ball valve can also divert or alter the flow of the liquid through multiple ports.

Globe valve:

A globe valve is especially useful to modulate or throttle the flow of the liquid. Its spherical body has a stationary ring seat. On turning the knob, a disc-like device is released and raised upwards from the ring seat. The Z-shaped passage opened below allows the liquid to pass through the valve. You can turn the handle all the way up or only partially, depending on how much liquid you wish you let pass. They, therefore, function pretty much like kitchen faucets or hose bibs. Flow modulation and throttling is the biggest advantage of a globe valve as compared to all the others, which are mostly used to simply turn the flow on or off.

Gate valve:

Also known as a shut-off valve, a gate valve works by lowering a wedge-shaped metal gate to halt the flow. The gate is lowered or raised by twisting a wheel-shaped knob present on top of the valve. The greatest benefit of a gate valve is the gradual stoppage of flow rather than causing a sudden halt, also known as a “water hammer”. A water hammer causes the liquid to suddenly change direction or abruptly stop. These create pressure waves and loud banging noises inside the pipe. A gate valve is only useful to open or shut the flow of liquids rather than throttling the flow like a globe valve. A gate valve is best used in straight flow lines with minimal disruptions, restrictions, or diversions. You can actually get a physical demonstration of these valves from any dealer of industrial water pumps in Mumbai.

What is a VFD Control Panel?

by vemcoblogs -

Variable Frequency Drive or VFD are control panels that help control the speed of electric motors and feed pumps used in various industrial facilities. Each motor has a different frequency and voltage and hence, a separate VFD control panel is required to monitor and control them. 

With VFD panels, you can bring multiple motors with variable frequencies and voltages under one roof. This will also protect your motors from moisture, corrosion, dust, and other damaging elements. 

VFDs are a crucial part of any manufacturing plant. Without them, the plants will not be able to maintain their output consistently. It can also cause failures that can severely hamper the production capacity of the plant. 

Like other control panels, VFDs comprise a range of equipment such as:

  • Harmonic filters
  • Protective equipment such as relays, circuit breakers, and stabilizers
  • A bypass control to keep the VFD operational in all conditions
  • Programmable Logic Controllers (PLC) for advanced control
  • Communication equipment such as switches and modems
  • Temperature control equipment such as air conditioner or anti-condensation heater
  • Motor starters

Benefits of a Variable Frequency Drive (VFD)

Does your industrial facility need VFD? Absolutely! Here are the top 4 reasons why you should get a VFD for your manufacturing unit: 

  • Power switching and protection – VFD control panels act as an intermediary between the power source and your equipment. In case there is a short circuit or a power overload, it will cause the circuit breaker of the VFD to trip. This way, your drive or any equipment connected to the line will not get affected. 
  • Speed backup – The VFD panel doors usually have a frequency control potentiometer. This helps send command signals to the motor as per the operator’s settings. In case the VFD fails, a bypass switch helps keep the motors functioning.
  • Equipment protection – Any manufacturing plant workplace is filled with moisture, dust, and other damaging particles. It can be cumbersome to protect your equipment from these. Long-term exposure to these materials can damage the tools permanently. One of the major risks is chemical accumulation on the open connections that can negatively impact performance. Moreover, dirt accumulation can reduce the lifespan of the equipment too. 
  • Visual control – VFD panels can provide crucial real-time data on the drive’s energy consumption, frequency, and other diagnostic data that operators require. Operators can also use the embedded controls to shift frequencies or take precautionary measures as per the monitored values. 

NEMA Ratings

VFD control panels have different ratings from the National Electrical Manufacturers Association (NEMA). There are 13 ratings, some of which are: 

  • Type 1: General purpose, for indoor use, protection against solid foreign objects
  • Type 2: Similar to Type 1 but with extra drip shields
  • Type 3: Protecting the equipment from external weather conditions such as rain
  • Type 3R: For outdoor use
  • Type 4: Water-tight, shielding equipment from at least 65 GMP of water

You can choose a specific protection by VFD panels based on the NEMA guidelines for the best usability and equipment protection. 

How can VFDs reduce energy consumption?

VFDs can reduce energy consumption significantly and help save production costs. Traditionally, motors would need valves and dampers to control pumps and fans. This would consume huge amounts of energy. VFDs can do the same without consuming so much energy. Moreover, the flexibility to adjust fan and pump speeds offers more control to operators to save energy.

Overview of Multistage Centrifugal Pumps: Here’s All You Need to Know

by vemcoblogs -

Multistage centrifugal pumps have been growing in popularity in recent years. Many engineers choose them because of their flexible flow range and excellent energy efficiency.

But are they a right fit for you? Let’s find out.

What are multistage centrifugal pumps?

A multistage pump is a category of pump that contains 2 or more impellers that can be of the same or different types. The impellers can be mounted on the same or different shafts. In case the outlets require high pressure, the impellers can be connected in a series. For high flow output, they can be connected parallelly.

What is the difference between a single stage centrifugal pump and a multistage centrifugal pump? 

The primary difference between single and multistage centrifugal pumps are the number of impellers or stages present. As the name implies, single stage impellers have only one impeller whereas multistage pumps have two.

The impeller of a centrifugal pump helps pressurise and transfer the liquid. Since multistage pumps have multiple impellers, they have better pressure ranges and flow rates than single stage pumps.

Where are multistage centrifugal pumps used? 

Multistage centrifugal pumps have a wide range of applications. They can be used for delivering water to high-rise buildings, reverse osmosis (RO), boiler feeder water, high pressure cleaning, water works, fuel delivery, oil and gas production, mining and other industries where high pressure and temperature are necessary factors.

What are the different types of multistage centrifugal pumps?

There are several kinds of multistage pumps: 

  • Horizontal Multistage Centrifugal Pump
  • Vertical Multistage Centrifugal Pump
  • Submersible Pump
  • Horizontal Split Case Pump
  • Vertical Turbine Pump

What are horizontal multistage centrifugal pumps?

Horizontal multistage centrifugal pumps are those that have two or more impellers and where the liquid travels horizontally. In this case, each stage acts like a separate pump. These are ideal for services that require moderate to high Total Dynamic Head (TDH). A single horizontal shaft can house up to eight stages. 

What are vertical multistage centrifugal pumps?

Vertical pumps are not that extensively used as horizontal pumps and have limited applications. As the name implies, their orientation is vertical where the impellers are placed on top of each other. The clearances in vertical pumps are also smaller than horizontal ones which makes them suitable for clean water applications. Moreover, if there’s a floor space crunch, these pumps can fit in well too.

7 Effective Ways to Improve your Air Piping Design

by vemcoblogs -
Air Piping
Air Piping

Have you discovered recently that you are not getting the most from your compressed air systems? Air compression systems need a lot of investment. So, if they are not performing at their optimum, there’s a need to investigate further.

One of the usual suspects in the case of inefficient compressor systems is the air piping design within the system. Often, improving it can go a long way in boosting the efficiency of your air compressors. This also ensures that the tools within your compressor are getting adequate air to function optimally.

Having problems with air supply? These are some effective ways you can improve the air piping design and make your air compressor systems more efficient:

1. Eliminate quick couplings – Quick couplings, despite their benefits, can increase the chances of leakage. You should avoid using them, except when you require a fast and easy disconnect of the hand tool or paint gun. In all other scenarios, connecting your machine to a hard pipe or a flexible connection with a hose pipe should be more than enough. 

2. Consider the pipe length – The length of airflow directly impacts the pressure in your machines. The longer the airflows, the more significant the pressure drop. Hence, pipe length should be an important factor for consideration when optimizing your piping design. Understanding your compressed air needs and aligning pipe length accordingly can be beneficial in making your system more efficient. 

3. Evaluate the pipe diameter – Pipe diameter too plays an important role in determining whether your systems are receiving adequate air or not. Consider this — will you draw enough air into your lungs from a straw as compared to without it? In the same way, the pipe diameter should be big enough to ensure adequate air flow into the systems. Trying to pass high-volume compressed air through a small diameter pipe can be detrimental. The high velocity can cause more friction and lead to a significant loss in air pressure. This would be reason enough to choose a pipe with an appropriate diameter after careful consideration. 

4. Reduce piping elbows – Nothing affects air pressure as much as piping elbows. Those sharp changes in direction severely impact air pressure. So, fewer the elbows, the better. If you must use piping elbows, the long radius elbows are a better choice. This is because they cause lesser friction than the short radius ones and hence, lead to lesser pressure drops. 

5. Check the size of components – Ensure that you don’t overlook the size of your components when optimizing your piping design. When the filters, valves, regulators, and quick connections, are appropriately sized, they improve the airflow in your systems significantly. When they are undersized, airflow gets restricted and consecutively, pressure is reduced. It’s also important to avoid quick connect couplings as much as possible since they lead to considerable pressure drops. 

6. Eliminate leakage – Testing regularly for leakage in your compressed air systems is a must to ensure their optimal functioning. The most common material used for piping is PVC and PVC pipes become brittle with usage. In comparison, aluminium and copper pipes leak less. Aluminium also has the added advantage of not rusting or scaling. This helps keep your air compressor system clean. The common phrase “a stitch in time saves nine” applies here — repairing the smallest of leaks can save you a fortune in annual repair costs. 

7. Consult air compressor experts – It may not be possible for you to know all the nitty-gritties of your piping designs. Thankfully, there are air compressor experts, like VEMC, who can help prevent unnecessary breakdowns or repair expenditures. 

With these tips, you can successfully get the most out of your air compressor systems. An efficient compressor system can help save money and time, while offering smoother airflow. 

For your reference, here’s a chart to guide you in choosing the right pipe length and diameter for your compressed air systems:

5 Reasons Why It Is Worth Investing In Solar For Companies

by vemcoblogs -

Solar power is becoming increasingly popular among companies in India. With the country becoming a proponent of solar energy globally, India’s total installed solar energy capacity has increased 19.3 times in the last 8 years. Many organisations are considering investing in solar energy and with good reason. For them, it’s a win-win situation. Energy costs make up for a large proportion of expenses for businesses, both big and small, and hence, cost-efficiency is always a critical goal. There is also the need to be socially responsible and include sustainability in brand ethos. Solar energy helps them meet most of these goals.

So, if you are considering making the switch to solar energy, it could be absolutely worth it.

5 reasons why solar energy is worth investing in

1. Reduced overhead expenses – Going the solar route can help companies save huge on energy costs. Since most of the things in a workspace, such as computers and electrical equipment, run on power, solar energy can help reduce dependency on erratic energy sources. The fluctuating prices of non-renewable fuels too will not affect you. You can let solar energy take over the majority of your existing energy sources. This way, you have more control over the quantity and cost of energy. 

2. Dependable power supply – Power outages are not uncommon in India and unreliable power supply can create interruptions in business. With solar power, you can expect a reliable and stable power supply. India’s total land area gets about 5,000 trillion kWh with most parts receiving around 4-7 kWh per sq. m. per day. Hence, with solar panels in place, you can generate sufficient solar energy to run your operations. 

3. Ease of maintenance – Installing solar panels in your workspaces can be an efficient and one-time investment. They are made from durable materials and can be long lasting. You can rely on expert solar panel EPC companies, such as VEMC, to help assess your energy requirements, check the available installation area, confirm the budget, and install the solar panels accordingly. 

4. Long-term savings – Solar energy helps save costs in the long run. You will need to make a one-time investment for the installation. Post that, you can start enjoying the returns on your investment. The maintenance costs are not exorbitant either. 

5. Sustainable and ideal for CSR – Investing in solar energy can help save the environment. You will be able to invest in a clean energy source, cause less pollution, and reduce your dependency on fossil fuels. Solar power also makes for a good investment to meet your corporate social responsibility (CSR) goals. This can help you stand out to your customers and investors as a green company with low carbon footprint.

4 Interesting Ways Compressed Air Is Used

by vemcoblogs -

Beyond the traditional applications, air compressors are used for, there are several unique ways in which compressor systems can be used. The amazing feats your air compressors are capable of are sure to leave you surprised! These are unconventional arenas, further away from the traditional applications such as in the manufacturing, pharmaceutical, and food and beverage industries. 

It can, in fact, help power some of the most ambitious projects of human beings. Looking beyond conventional uses can help you realise the true power of your air compressors. 

Let’s look at 4 such unconventional applications: 

1. Artificial Snow – If you think all sky-high hills are natural, think again. Organic, white, and fluffy snow is not as easy to procure. However, they can surely be created artificially. Compressors are an indispensable tool to achieve this. The huge machines that create lofty hills of artificial snow depend on water from compressed air at the right temperature and humidity. And voilà, you have snow on demand!

2. Projects by NASA – Air compressors also help power space shuttles at the International Space Station (ISS). Two of the most important applications of compressors are to launch space shuttles and help sustain human life in space. 

For example, the speed required by space shuttles to escape the Earth’s atmosphere is around 25,000 mph. This feat is achieved by compressors along with turbine engines. Without compressed air to increase pressure and deliver liquid hydrogen and liquid oxygen to the engines, they won’t be able to combust fuel effectively and provide adequate energy.

Also, human life in space is heavily dependent on compressors. Compressed gas, when introduced into space, and decompressed and mixed, can act as a precious source of oxygen. From a real-life example, when ISS was launched into space, compressors were used as the primary backup for oxygen. 

3. Roller Coasters – Not just scientific inventions; compressors find applicability in recreational activities as well. The air brakes, safety gates, special effects, and launch systems are all powered by compressors. This helps create an other-worldly experience for people and makes it safer for them. Compressed air in roller coasters also help them run on water and reduce the need for electricity. 

4. Trains – Can you imagine the speed at which freight and passenger trains run? It’s around 220 mph. However, the essential thing is not only to move at that speed, but also to stop when required. This is where air compressors come in. The brakes in these trains run on compressed air. Compressors provide the force which closes pads onto the discs and blocks the wheels, thus forcing the trains to stop. 

Air Compressors for your Industry

Compressor systems can be a powerful resource for any industry. It can help bring to life some of the biggest ideas of mankind. Whichever industry you are in, compressors can help power your operations. Vijay Engineering and Machinery Company (VEMC), an ISO 9001:2015 certified company, is a pioneer in the field of electromechanical engineering products, allied equipment, and services.

Solar Power: An End Date to Your Energy Bill

by vemcoblogs -

Most of us are used to paying our energy bills as per our electricity usages. The bills come in monthly, we pay them, and wait for the next one the following month. That’s how the cycle continues. If you analyse your energy bills over the years, you’ll observe a trend that indicates increased expenditure. But most of us don’t give much thought to it since we don’t have an alternative.

Solar Panel ROI: Calculate How Much Your Solar Savings Will Be

What if you could find an alternative that could help you beat the rising energy costs? Imagine having a lifelong subscription to clean energy and renewable energy independently. Solar power installation can help in achieving this successfully. 

Understanding your current energy model

Presently, we are dependent for our energy needs and whenever we need to consume power, we have to pay for it. This infinite cycle exists for the ones who haven’t made the shiftto solar power yet. 

The issue with this model is that your source of energy is dependent on you paying your bills indefinitely. However, the price of electricity hasn’t remained the same. For example, duringthe period 2009-2020, the cost of state electricity has doubled—from INR 3.4 per kwh to INR 6.15 per kwh.

Add to this the present state of climate change where the summers are getting hotter. This will inevitably lead to significant increase inenergy needs. On a global scale, the demand for energy will rise, leading tofurthersurge in the price of fossil fuels. 

Hence, as long as you’re tied to the present model, your energy costs are likely to go up exponentially. 

So, what’s the alternative?

Thankfully, there’s an alternative to this — switching to solar power. The shift can give youmore control overyour monthly energy payouts. A solar power consultant, like VEMC, can help design a system that perfectly fits your budget and needs. With the right guidance and the right model, solar power can be easily accessible foryou. This will be an investment that would offervalue in the long-term and will be sustainable too. 

Once you move to the new system, your current usage will be mapped and any additional usage will be accounted for. Once these are done, you won’t have to pay a monthly bill anymore. You would simply pay for the usage once the sun sets down and you can waive that off to by investing in a solar battery.

What are the Different Types of Fire Fighting Pumps?

by vemcoblogs -

A fire can be a terrible hazard in any industry. At a power station, taking measures to prevent one as well as being prepared to deal with one in the event that it occurs, is absolutely crucial. Installing fire fighting pumps is an effective way to combat such a hazard. A fire pump is part of a sprinkler system’s water supply. It is powered by steam, electricity or diesel. Let’s examine some of the different types of fire fighting pumps that you can choose from, for your power station.

Sprinkler Pump

The sprinkler pump is commonly used to irrigate plants and greenery in gardens, and also to prevent fires. In a fire sprinkler system, the fire pump is an essential component. It provides access to high-pressure water in the fire sprinkler system, which serves to increase the rate of the flow of water. The sprinkler pump is a popular method of fire prevention in factories and power stations.

Booster Pump

The booster pump machine is part of another system to fight and suppress fires. A booster pump will increase the pressure of a fluid, which may be liquids or even gases, depending on its construction. A gas booster is much like a gas compressor but is usually built with a simpler mechanism, often with only a single stage of compression. This is used to increase the pressure of a gas which is already above the ambient pressure.

Jockey Pump

A jockey pump, also called a pressure-maintenance pump, is a small device that works with a fire pump in a fire fighting sprinkler system. It is designed in such a way that it keeps the pressure in the system raised at a certain level when the system is not in use, so that the fire pump does not have to run all the time and the system does not get set off without actual cause for alarm. The jockey pump helps make sure that your fire fighting resources are used efficiently, without wastage.

Drencher Pump

The drencher pump is another part of a fire fighting system which consists of water heads. Unlike sprinklers, which are built internally, drenchers are usually placed on the outside of a building to protect against a fire which may have broken out in a nearby building. Drencher pumps are found above windows, roofs and other exterior openings.

Water Curtain Pump

The water curtain pump is part of a water curtain system — another active fire fighting system. As the name suggests, a water curtain system forms a curtain of water in the event of a fire, to prevent the flames, heat or smoke from spreading further. A water curtain pump is connected to the nozzle of this system through a deluge valve. When fire or smoke is detected, a signal will be sent to the deluge valve to open up and switch on the pump. This will cause water to come gushing in and reach the nozzles and help put out the fire.

VEMC, an authorised Kirloskar pump dealers, supplies fire fighting pumps for different kinds of industrial purposes. We offer a diverse range of pumping solutions, including water pumps and containerised fire fighting pumps.

What are Valves? What are their types and applications?

by vemcoblogs -

No matter which supply system you are talking about, one piece of equipment is absolutely indispensable — valves. Why are these so important for the proper functioning of your supply system and which valves suit your needs the best? In this blog, we touch upon all these fundamental questions about these ingeniously simple yet essential instruments.

Valves are simply instruments that control, regulate or direct the flow in a supply system. These are used in pipelines carrying liquids such as water, oil, and chemicals, or gases such as natural gas and cooking gas. The most basic function of valves is to completely start or stop the flow. However, they are also used to regulate the flow or pressure, throttle the flow rates, and improve safety by relieving pressure or vacuum in the piping system. Valves also prevent a backflow of the liquid or the gas. Let’s take a look at some of the main types of valves and their unique applications.

  1. Ball Valve: These have a quick-acting 90-degree handle to provide easy on-off control. These are faster and easier to operate as compared to other valves as they do not require a protracted winding action. These valves are mostly used in refineries, fertilizer plants, petrochemical processes and thermal power stations.
  2. Butterfly Valve: These have a characteristically compact design and are therefore best suited for cramped spaces. Their name comes from the wing-like action of the disc which operates at right angles to the flow. These find use in sewage plants, chemical processing and petrochemical plants.
  3. Spindle Valve: These valves have the simplest mechanism as they merely require twisting of the spindle wheel attached to the spindle rod. This moves the gate at right angle to the flow and stops it. These valves are mostly used in water supply.
  4. Foot Valve: A foot valve is typically installed at a pump or bottom of a pipe. These have an open end with a shield or screen over them to keep out debris. These can be found installed in ponds, lakes and pools on a pump. They let the liquid to flow in but prevent it from flowing back out.
  5. Sluice Valve: A sluice valve is a large valve with a rectangular or circular gate. On rotating the spindle, the gate slides across the opening. These valves find wide application in water works, effluent treatment, shipping, irrigation and thermal power plants.

VEMC at 73: Recollecting the Years Gone By

by vemcoblogs -

On 11th August this year, VEMC turns 73. A business spanning the better part of the last century speaks volumes about our experience, expertise and competence. On the occasion of our 73rd anniversary therefore, we decided to take you down the memory lane by recollecting the years gone by.

Vijay Engineering and Machinery Co. was founded in 1948 by Late Shri Sharad Kumar Shah along with Late Shri Rajaram Shinde, both entrepreneurs par excellence with a penchant for engineering and machinery. Their first office was a 100 square feet room at Commerce House in Ropewalk Street Bombay. During those days, erratic electricity even in urban and commercial areas, often compelled users to look for alternatives for running their equipment. The company saw this as an opportunity worth exploring and participated in an import auction of Petter Field Engines. The product, owing to its high quality, turned out to be a great success and gave VEMC a spectacular start.

During the 1950’s, VEMC made its way to various government projects and forged associations with many renowned companies. These included Kirloskar Brothers, WRT Talwalkar Pvt. Ltd., Bush Electricals and MICO Full Injection Equipment Company. The diverse nature of these projects vastly added to our product basket and also to the depth of our client profiles. Strong emphasis on ethics-based business practices and customer-centred approach soon became the defining features of our brand.

The 60’s was a time of expansion for the company. In this period, the government framed policies that laid emphasis on providing basic necessities of life, especially water, to all citizens of the country. The dry hinterland of western India was an important focus area and became VEMC’s market for Vertical Turbine Pumps. After this, VEMC group took a bold step and went beyond their comfort zone of the western region, and established the Rajendra Engineering Company in West Bengal, as the state distributor of Cooper Engines.

Radical changes in the style of doing business were seen in the decades between 1970 and 1990. The scope of work changed from supply of products to taking up turnkey projects, especially in the water pumping business. With its dynamic leadership at the helm, VEMC was up for the challenge and established Shailesh Engineering in Bangalore, a company that mostly handled turnkey projects for government’s water supply scheme and thermal power plants.

As the Indian economy opened up in 1991, new challenges came our way. Multinational companies began making in-roads into the Indian market giving VEMC and its partners a very stiff competition. However, the many years of trust and high-standards of service now bore fruit as the company remained unfazed in the wake of this altered situation. In fact, new avenues, such as building and construction began opening up to VEMC. In 1996, VEMC was awarded as the number one channel partner across India! In the period from 2003-08, the company grew at a rate of 20% CAGR, owing largely to its government projects.

Thus, after years of arduous efforts and strongly rooted business ethics, VEMC has been able to carve out a unique brand image for itself: one that emanates unfailing trust, relentless confidence and an inspiring vision for the future.

How Solar, Wind, and Hydropower can Outclass Coal Energy

by vemcoblogs -

For a very long time in modern human history, coal dominated the energy market as the cheapest, most easily available, and readily combustible source of energy. Coal energy was in fact the force behind the Industrial Revolution and continued to power factories, trains, and smelting furnaces, even into the twenty-first century.

However, today there is a huge concern to shift our energy demands from fossil fuels such as coal to renewable energy like solar, wind, and hydropower. This is due to the growing awareness about environmental issues and also the exhausting fossil reserves across the world. In the developed world, the transition is already evident, with shrinking demand for coal in the electricity sector. More and more power plants are switching over to solar and wind farms as the main source of energy to generate electricity. In the US, the Energy Information Administration (EIA) reported that the demand for coal in the electricity sector shrank from 28% in 2018 to 22% in 2019 (source).

As declining reserves of coal impact supply and leads to increased prices, renewable energy will be seen as a more cost-effective source of energy. This will draw the commercial sector further towards renewable energy as it will not just make them more compliant with their environmental legislation but also help them cut their energy bills and improve their margins.

India has set itself a target of producing 175 GW of renewable energy by 2022, out of which 100 GW will come from solar energy, 60 GW from wind, 10 GW from biomass, and 5 GW from hydropower (source). Increasing reliance on non-fossil energy is especially important for India to keep threats from climate change under check while its economy grows at a steady pace.

Critics take an interesting line of attack at renewable energy: The sun doesn’t always shine and the wind doesn’t always blow. This seems like a valid criticism but overlooks the stupendous growth of research and innovation in renewable energy (especially solar energy), backed by generous funding. This has greatly enhanced the storage systems so that the energy is used as and when needed. This has also placed renewable energy on the trajectory of increasing efficiency and declining equipment costs.

As fossils fade away into the background of the energy conundrum, renewable sources of energy like solar, wind, and hydropower will form the dominating portfolio for our energy needs of the future.

Types Of Solar Panels And The Best Fit For Your Commercial Needs

by vemcoblogs -

One of the foremost choices to make when it comes to procuring a solar system is with regards to the type of solar panel you wish to install. There are broadly three types of solar panels available and each differs from the other in terms of cost, efficiency and aesthetics.

Monocrystalline Panels

This type of panel gets its name from the fact that each cell in the panel has a single crystal of silicon which allows free movement of electrons through the cell, taking its efficiency upto 20% and more. High efficiency means lesser requirement for space and hence, these panels are best suited for residential use as space can be managed efficiently. Monocrystalline panels contain either 60 or 72 cells, depending on the size of the panel. The silicon cells are in the shape of black squares with their corners cut off, giving the panels a deep black aesthetic look.

Polycrystalline Panels

Multiple crystals go into making each cell in these panels which restrict the free flow of electrons through the cell. Their efficiency ranges between 15% and 17% but with increasing innovation in technology, this is expected to improve. Compared to Monocrystalline panels, these panels require more space and therefore, may be slightly challenging to accommodate in a residential setting. These panels also contain 60 or 72 cells but multiple crystals give them a marbled blue appearance, which may not be aesthetically pleasing. However, Polycrystalline panels are more affordable which, despite factors like space and efficiency, has enabled the product to make galloping strides even in the residential market segment in recent years.

Thin Film Solar Panels

These panels are solid black in colour and do not have any silicon cell outlines. Being lightweight and flexible, these are easy to carry and install. Thin-Film panels are the least energy-efficient (10-13% range) and are only suitable for large establishments like industries and utility solar projects with ample space. Being extremely cost-effective due to low energy efficiency and ease of installation makes these panels all the more suited for large-scale commercial establishments. These have a very short life expectancy and require frequent replacement. Depending on the material they’re made of, these panels can be both blue and black.

6 Tips to Finding the Right Solar Installer Basis Your Requirement

by vemcoblogs -

Finding the right solar installer could be a challenging task as the market is flooded with installers claiming to have the required know-how. There are a number of aspects that must be considered while choosing the right professionals in the field. Here are 6 tips that will guide you in your quest for the right installer:

  1. Expertise: As the solar industry is rapidly expanding, there is growing demand for competent professionals with the right skills and expertise. In India, many solar installers go through formal training courses offered by reputed institutes like Indian Institute of Solar Energy and Gujarat Energy Research and Management Institute (GERMI). Certificates from these institutes are the best authentication for skills, knowledge, and expertise.
  2. Track record, experience, and references: Projects with previous clients could provide a good understanding of the level of experience an installer has. An installer must be thorough with the systems installed for other clients and be able to confidently discuss and demonstrate the projects. Speaking to their past clients could be a great way to find out how their installation was handled.
  3. Reputation in the market: Many online forums and sometimes, even the installers’ websites or social media pages can provide valuable insights into their clients’ experiences. A pattern of negative comments and customer complaints would indicate that you need to select another installer.
  4. Use of subcontractors: While installation by subcontractors is a common practice in the industry, there must be complete disclosure and transparency about their expertise, reputation, and track record. It will be important to fix responsibilities and confirm who stands behind the quality of the system.
  5. Warranty: What is the warranty being offered on the equipment? To give you a rough estimate, the average warranty offered on solar panels in around 20 years, and that on batteries and inverters is 5-10 years. Warranties shorter than this can indicate that the quality of the equipment is not up to the mark. 
  6. Competitive quotes: Finally, it is always recommended that you contact as many installers as possible and gather quotes, especially in a business-to-business scenario, where competing bids can help save expenses significantly. The contractors can prepare their bids only after visiting your facility to ascertain the various equipment, labour and logistics costs that will go into installing the system.

With the help of these tips, you can confidently stride towards the solar transformation of your facility.

Difference Between A Centrifugal Pump And A Vacuum Pump

by vemcoblogs -


Centrifugal pumps and vacuum pumps differ from each other for multiple reasons, and here is the detailed explanation for both that reflects those reasons: 

Centrifugal Pumps 

Popularly known as hydrodynamic pumps and dynamic pressure pumps as well, centrifugal pumps are manufactured by making use of the primary centrifugal forces. The flow happens when the kinetic energy produced with the help of a rotating turbine or electric motor is turned to pressure in the liquid. 

If kept in comparison with a vacuum or any other pump for a fact, these water pumps are easier to install. Unlike others, they are manufactured with the help of the back pullout-design process. When a repair is required, the parts can be taken apart and restarted within a short period.

Vacuum Pumps 

Vacuum pumps are those types of submersible pumps that are used to pump out the gases, leaving a partial vacuum aside. While choosing the best vacuum pump among many, the flow of air removal in the pump, the amount of vacuum that is produced, and the power required to create the vacuum are some of the factors that need to be considered. Keeping this in mind, it’s mandatory that the manufacturers should provide information on flow-rating availability. 

When put in comparison with other pumps used in submersible motors, vacuum pumps have comparatively lower power requirements. For continuous pumping, large-sized vacuum pumps are put to use. The only drawback that vacuum pumps have that centrifugal motor doesn’t is that they get overheated if put in continuous use. 

Be it centrifugal pumps or submersible motors, VEMC provides only the best and proves that it is one of the renowned pump dealers in India and the trustworthy distributors of the reliable Kirloskar pumps. Whether it is the best water pump dealers in Navi Mumbai or topping the list of pump dealers in Vashi, VEMC has never failed to excel. Check out our website for more!

On-Grid or Off-Grid

by vemcoblogs -

Many people think that whenever one switches to solar energy, the only option they have is to install an off-grid system, especially in rural areas, where extending the power lines is difficult and expensive. But before you make a hasty decision, a better idea is to consider the two options in front of you- off-grid solar system and on-grid solar system. 

Here are a few differences between the two: 

  • On-grid basically means that your solar system is connected to the local company’s system eg. MSEDCL, Adani, BEST. Generally, residential homes opt for on-grid solar systems where there are good grid parity and lesser downtime. Whereas, the off-grid system means that you’re not connected to any utility company. 
  • Using the on-grid system, the extra energy produced that’s not used by you will be stored in the grid’s power company. This stored energy will act like a credit that can be cashed out at the end of the year as per the local distribution norm. Whereas, using an off-grid system, you’ll need to install a backup battery for storing energy this way. As there is no good parity and a higher electricity outage dependency on battery storage of electricity which makes more sense and has longterm financial viability. But the challenge is that this battery is rather expensive thus increasing the cost spent on installing the off-grid solar systems.
  • Though over the next 5 years the cost of battery storage shall be reduced due to the higher scale of economic order quantity. 

So stay calm! Leave the extra work to Vijay Engineering and Machinery Company, the best solar EPC consultants in Thane. We will ensure that you get the services that will benefit you the best- so whether it is choosing the right grid system or its proper installation; we are at your service!

What is an Isolation Valve, and in what conditions is it used?

by vemcoblogs -

An isolation valve is used to manage the flow of fluids in the plant process and prevent it from flowing to a specific location. The primary purpose is to prevent the flow of contaminated components such as blood, pharmaceuticals, or any medical devices.

Isolation valves come to use under multiple circumstances and for various technical equipment as stated below: 

  • Firewater control 

Firewater pumps are extremely risky and dangerous to handle, especially when they need to be removed. But, isolation valves ensure the safe removal of firewater control pumps and prevent any impact on the entire system of the centrifugal motor.

  • Pipeline safety

The blockage of drain lines or water pumps is quite a common issue due to ice or hydrate formation. The worst cases might even include an uncontrollable situation where the submersible pumps freeze open and are impossible to be shut back again. To avoid such mishappenings with the motor, isolation valves could be installed between the inventory and expected leakage area of the submersible motors, eliminating the scope of any leakage in the future. 

  • Oil and gas wells

Valves in the oil and gas industry ensure confidence and reduce any unforeseen risks. Every industry or plant must adhere to the safety and health guidelines provided as per the government, where oil and gas industries are quite prone to damage to the environment. Even a small gas leak in centrifugal pumps can lead to substantial environmental concerns in the future. The stem seal designs of isolation valves prevent any such leakage and ensure adherence to the social and environmental guidelines. 

Hailed as the best pump dealers in Mumbai, Vijay Engineering and Machinery Company is regarded as one of the most reputed pump dealers in India and trustworthy distributors of the reliable Kirloskar pumps. From being regarded as the best pump dealers in Navi Mumbai to being the trusted pump dealers in Panvel, VEMC lives by its principle to never compromise on what is best for its customers.

What is a water hammer? What are its ill effects?

by vemcoblogs -

A water hammering  effect happens when a sudden closure of the valve causes the back and forth movement of water at supersonic speeds. Water hammer is an understudied topic, and unaware of the fact that residentials have it in their submersible motors, nobody seems to care. In the light of water hammer- for residentials, it’s just that loud noise when the submersible pumps are shut. 

Having said that; a water hammer could have some adverse effects as stated below: 

  • When a centrifugal pumpset suddenly shuts at any given site, the mass of water before closure will still be moving, hence a high pressure shall be created, resulting in a shock wave. This process makes a similar hammering sound that one often hears after shutting their centrifugal pumps.
  • In the worst case, water hammers can even cause the pipelines to break if the pressure is too high. For safety purposes, air traps are often installed to absorb the damaging factors caused by high pressure.
  • The water hammer can also harm valves and pipes in case of any water, oil, or gas application. This happens in the same process of high pressure, as mentioned above, which causes a spike, thereby damaging gauges. This can occur even if the gauge has a correct pressure range for the flow application.

To avoid these adverse effects of a water hammer, air chambers prove to be quite useful because they soften the impact and hence prevent the hammer effect.

But you can swiftly avoid the chances of a malfunctioning water pump, by opting for the high-efficiency Kirloskar pumps that Vijay Engineering and Machinery Company, the best pump dealers in Mumbai, promise to provide to you. Counted amongst the reputed pump dealers in India, VEMC is the answer to your problems!

In which direction does water enter the centrifugal pump?

by vemcoblogs -

So, how does water enter the centrifugal pump? Well, there are different ways in which it makes it to the eye of the impeller in the pump:

  1. End suction and top discharge centrifugal pump:

 In this arrangement, the water enters the impeller horizontally and then proceeds to discharge vertically from the top of the pump, a good example of which is the single stage horizontal centrifugal pump popularly known as end suction back pull out pumps

  • Top suction and top discharge centrifugal pump:

The water both enters and discharges from the top of the pump,i.e. top half of the casing  something which happens in a boiler feedwater pump.popularly known as Multistage pump.

  • Side suction and side discharge centrifugal pump:

Here, the water both enters and exits from the same direction, but in this case, it is from the side.i.e. bottom half of the casing. A classic example of this type of arrangement is an axial split horizontal centrifugal pump. Popularly known as side suction side discharge pump

No matter which method is employed, they are available in a variety of options and are applicable in several applications.

So, if it is centrifugal pump you seek, VEMC stands by its promise to provide only the best to you as the renowned distributors of the reliable Kirloskar pumps, making it one of the best pump dealers in Navi Mumbai, Mumbai and Raigad Districts
