Crucial Role of Mechanical Seals in Centrifugal Pumps

by vemcoblogs - August 22, 2024August 30, 2024

Mechanical seals play an important role in centrifugal pumps when it comes to preventing leakage of fluids. Besides, these also help maintain pump efficiency, manage pressure and temperature, protect the pump from contamination and improve longevity and reliability. VEMC is one of the leading industrial water pump dealers in Mumbai, and in this blog, we talk about the crucial role of mechanical seals in your centrifugal pumps.

How mechanical seals prevent leakage between the rotating shaft and the pump housing

Mechanical seals have two seal faces: one fixed to the pump housing and the other to the rotating shaft. Both faces have smooth finishes to ensure tight sealing and are made of water and chemical-resistant material with low friction properties.

The two seal faces are connected through a spring mechanism which helps keep them together even as the faces wear out over time. A flush or barrier fluid may also be present between the seal faces to prevent the fluid from reaching the seal faces. This improves the longevity of the seals.

Besides the primary seal faces, mechanical seals often also have O-rings, gaskets or elastomers to offer an additional layer of protection against leakage. For proper sealing, the mechanical seals must be installed with precision, the spring aligned correctly and lubricants or barrier fluids used as required.

Types of seals

Single mechanical seal: These are the simplest mechanical seal types. These are directly exposed to the pump and fluid pressures.
Double mechanical seals: These have two seal faces with a space between the two which is filled by a barrier or buffer fluid. These are suitable for handling highly valuable or toxic fluids.
Cartridge seal: These come as a single unit consisting of seal faces, springs etc. in a cartridge. These can be replaced as a single unit without the need to disassemble the pump.
Split mechanical seal: Disassembly may be quite hectic for large pumps or those installed in small spaces. Split mechanical seals are specially designed for such pumps. They can be installed without removing the pump shaft.
Component mechanical seal: These are also known as non-cartridge seals and are installed piece by piece. They are often used in custom settings where standard seals may not work.

Seal inspection and replacement

No matter which type of mechanical seal you use, they will wear out over some time. This could have severe implications as it could jeopardise the very functioning of your pumps. The only way to avoid this is to regularly inspect your seals, and replace them as soon as they’re worn out. Damaged seals can reduce the working efficiency of your pumps by causing frequent leakages and malfunctions.

Understanding Pump Efficiency and its Impact on Energy Costs

by vemcoblogs - August 19, 2024August 23, 2024

When purchasing a pump, it is important to ascertain how efficiently it converts electrical energy into mechanical energy. Energy costs are rising the world over and businesses across the board need to streamline and improve their operational efficiency. VEMC is a leading Kirloskar pump distributor based in Mumbai, and in this blog, we tell you all about pump efficiency and its impact on your energy costs.

How pump efficiency measures the conversion of electrical energy into hydraulic power

Pump efficiency indicates how well a pump can convert electrical energy into hydraulic power, that is, the power delivered by the fluid that is being pumped. This can be better represented by the following equation:

η = Hydraulic Power Output

––––––––––––––––––––

Electrical Power Input

(Where η stands for pump efficiency)

Low efficiency means high energy costs

Low pump efficiency has a direct correlation with high energy costs. This is because of the following reasons:

Heat loss: Low-efficiency pumps lose a significant part of their energy as heat rather than hydraulic power.
Higher consumption: If the pump is less efficient, more amount of electric energy is consumed to perform the same amount of work, that is, pumping the fluid.
Environmental impact: Less efficient pumps contribute to more emissions and the resulting climate change.
System design alterations: Systems that use less efficient pumps may require electrical systems of a larger capacity to provide the necessary power.

Use high-efficiency pumps to reduce your energy bills

As energy costs rise sharply, users across the world are looking for energy-efficient options to switch over to. High-efficiency pumps are highly recommended to reduce your energy bills over a period of time. This is because:

High-efficiency pumps reduce energy consumption.
These pumps are more sustainable and have a lower impact on the environment.
These pumps are typically reliable, have a longer working life, lower downtime and require less maintenance.
Many local and national governments offer incentives such as rebates on electricity bills if you install high-efficiency pumps.
These pumps are made with advanced technology and thus have a greater potential for savings.

How to choose a high-efficiency pump

When buying a pump, look for High Energy Star ratings or other efficiency ratings which indicate higher levels of efficiency. Some of the globally renowned standards of efficiency are:

Energy Star Certification by the US Environmental Protection Agency (EPA)
CEE (Consortium for Energy Efficiency) Tier Ratings
EU (European Union) Energy Label
ASHRAE 90.1 Standards
ISO 5199
Hydraulic Institute Standards
Pump Efficiency Index (PEI)

When choosing a pump, look for both initial costs and the lifecycle costs. The latter especially includes the amount of energy the pump is expected to consume over its working life.

How to choose a fire fighting pump that meets the specific flow rate and pressure requirements of a building or fire protection system

by vemcoblogs - August 14, 2024August 23, 2024

If you own a building, a factory or any other facility, you would appreciate the importance of firefighting pumps for the safety of property and lives on your floor. However, having a firefighting pump with a specific flow rate and pressure is important for adequate building protection. VEMC is the leading Kirloskar fire pump dealer, and in this blog, we tell you all you need to know about choosing the right firefighting pump.

What is flow rate and pressure?

Before we begin discussing the importance of matching the flow rate and pressure of your firefighting pump to your demands, let’s understand what the two terms mean.

Flow rate refers to the volume of the fluid that your pump is capable of moving. It is measured in litres per second (L/S). It thus determines the amount of water that can be sprinkled through your firefighting pump in times of a breakout.
Pressure on the other hand is the force per unit exerted on the walls of a pipe through which a fluid flows. In the context of a firefighting pump, this indicates how far and forcefully water can be sprayed during a fire emergency.

Factors that determine the choice of firefighting pumps

Building size: It is common sense that larger buildings will need more powerful firefighting pumps. Likewise taller the building, the more pressure will be required to reach the upper floors. Besides, buildings with complex and irregular layouts will also need pumps which deliver to multiple zones simultaneously without loss of pressure.
Sprinkler system needs: The type of sprinkler system you’re using will also determine the pump requirements. Different sprinkler systems have different coverage areas or densities. Fire pumps should be able to supply the right flow rate and pressure to meet the demands of these different sprinkler types.
Number of floors: The more the number of floors in a building, more will be the pressure required from your pump. Besides, if sprinklers are installed in different zones, you will also need a pump with more pressure to make up for losses due to multiple sprinklers.

Work with fire protection professionals

The above information may seem baffling for a layman but can be processed ably by a fire protection professional. They have the required expertise and experience to deal with fire safety issues and can effectively guide you in selecting the right firefighting pump. They’re also acquainted with fire safety laws and local regulations which can add an extra dimension to your pump selection decision. Local fire safety codes are after all meant to ensure that your fire safety pump meets all the legal requirements.

Preventing Cavitation in Your Centrifugal Pump

by vemcoblogs - August 12, 2024August 23, 2024

Cavitation is the bursting of air bubbles in the fluid inside your pump. When this happens, tiny but high-energy shockwaves are created inside the pump which can erode its internal components and lead to rapid deterioration. Curbing cavitation to prolong the working life of your centrifugal pump is therefore important. VEMC is the leading Kirloskar pump authorised dealer, and in this blog, we tell you how to prevent cavitation in your centrifugal pump.

How cavitation can damage pump components

Shockwaves created due to cavitation can gradually erode the internal pump components. Besides, repeated cavitation can also increase the surface tension of the components eventually leading to fatigue, failure, weakening of material, cracks and fractures. The noise and vibrations that cavitation causes can further lead to wear and tear.

Factors leading to cavitation

Regions of low pressure: These are created as soon as the pressure of the fluid inside the pump drops below the vapour pressure of the liquid.
Changes in flow velocity: Rapid changes in the flow velocity can lead to cavitation as it also creates regions of low pressure.
Temperature differences: Sharp changes in the temperature of the fluid can cause cavitation. This is due to the changes in vapour pressure that it causes.
Pump design: Inappropriate pump design or mismatched features as per the demand can result in severe cavitation.

Other factors that can cause cavitation are low-viscosity fluids, clogged flow, excessive speed or pressure.

Methods to prevent cavitation

Proper pump selection: For starters, choose the right pump based on your task requirements. Make sure the flow rate and head are in line with your demands.
Operational adjustments: Adjust the system design or use booster pumps to increase the suction pressure. Avoid running the pump at flow rates sharply different from its design point.
Fluid management: Control the fluid temperature and try to keep it within the safe range relative to vapour pressure. Reduce the introduction of gases into the fluid as it can increase the rate of cavitation.
Pump monitoring: Keep track of your pump parameters like pressure and temperature and try to maintain them within the desirable range.
Material selection and coatings: For your pump components, use cavitation-resistant material such as hardened alloys. Apply protective coatings to prevent erosion of vulnerable surfaces.
Operational practices: Avoid sudden changes in pressure, and prime the pumps properly to ensure no air pockets are formed within the pump.
Improve system design: Use flow control valves or devices to stabilise flow rates. Change the system piping and place flow straighteners at the inlet for smooth and non-turbulent flow.

Cavitation can be prevented by regular inspections and maintenance. The most common signs of cavitation are noise, vibration, reduced performance, variations in flow and pressure, increased power consumption and damaged bearings and seals.

Strategies for Maximising the Efficiency of Your Centrifugal Pump System

by vemcoblogs - August 8, 2024August 8, 2024

If you are a pump owner, you would appreciate the importance of savings on precious electricity units in their operations. The bills for multiple pumps in big businesses could be quite humongous. VEMC is one of the leading Kirloskar pump dealers based in Mumbai, and in this blog, we talk about the various strategies to maximise the efficiency of your centrifugal pump systems to save energy costs.

Choosing the right impeller design

If you wish to improve your pump’s performance and efficiency, being mindful of the impeller design is important. Two main factors play a part in this:

Impeller size: A larger impeller size naturally means the pump can move a greater fluid volume. But to maintain optimum efficiency, make sure you are selecting the right-sized impeller. An improperly sized impeller also leads to cavitation, which reduces a pump’s efficiency and working life.
Material: If the impeller is made of robust material (like stainless steel) which can withstand corrosion, cavitation and mechanical stresses, it will be able to provide consistent efficiency levels over a longer time horizon. Abrasive fluids on the other hand can cause wear and tear, reducing both performance as well as the efficiency of the pump.

Pipe apparatus

If your pipe is sized too narrowly, it can impact efficiency by causing friction losses as the pipe wall offers more resistance to the flow. Likewise, too many bends in the piping can cause turbulence and excessive friction, reducing the overall efficiency of the system.

Impact of system head pressure

If you’re operating the pump at higher system head pressure, it will make the pump work harder and consume more energy. This will reduce the efficiency of the system and lead to higher operational costs. Running the pump on optimum system head pressure can help improve efficiency levels significantly.

Regular maintenance

Your pumps, like all other mechanical equipment, contain plenty of moving parts which over some time tend to wear out. This can reduce their efficiency and make them consume more energy. Regular preventative maintenance may have some costs, but it also helps save plenty on the energy front.

Monitoring pump performance and adjusting operating points

What you cannot measure, you cannot improve! If you’re not measuring your pump parameters like head or flow rate, you’re missing out on a lot of crucial information. Keeping track of these parameters and adjusting them according to your needs is an extremely effective strategy to maintain optimum efficiency levels. With IoT-based tools like KBL’s Kirlosmart, pump monitoring has now become quick, convenient, accurate and real-time.

If you’re struggling with huge energy bills because of your pumps, you may want to get them audited by our experts.

The concept of solar battery storage and its role in maximising solar energy use

by vemcoblogs - August 5, 2024August 23, 2024

Solar energy generation can fluctuate due to several reasons such as cloudy weather or night time. At other times (like during bright sunny summer days), your solar panel output could be boosted manifold. To level these crests and troughs and have a consistent supply of electricity, your solar battery storage can be extremely useful. VEMC is the leading solar energy company based in Mumbai, and in this blog, we talk about the concept of solar battery storage and how it can help maximise solar energy use.

Role of batteries in solar power

Batteries play a significant role in storing the excess solar power generated during the crests, such as on bright sunny days. But let us look at the elaborate function of batteries in solar energy systems:

Managing load: By supplying electricity during periods of high demand and storing it when the demand is low, batteries help even out the load and reduce the burden on the electricity grid, especially during peak times. Solar batteries in a way act as a grid support system by injecting electricity into the grid and contributing to its stability.
Backup support: In cases of sudden outages and load shedding, batteries can act as a buffer and provide ample backup to keep your domestic or business operations running.
Reduction of electricity charges: Batteries can reduce the electricity charges by supplying extra electricity during peak demand. This can help consumers save significant amounts of money.
Maximising self-consumption: Greater storage of electricity encourages users to consume it within their households and businesses. Excess energy generated during the day or sunny conditions is stored for later use, thus enhancing the energy self-sufficiency of the users. This also reduces the reliance of the users on the grid.

With batteries, use solar power at night and on cloudy days!

With solar power batteries in place, you no longer need to worry about energy supply at night or on cloudy days. This is because batteries store the excess energy generated during the daytime and over the longer time horizon, during the bright sunny days of summer. This energy can then be used when sunlight is not available at all, that is, at night or is not as abundant, like on overcast days. These solar power batteries play the role of levellers when it comes to electricity supply.

Cost-savings with solar batteries

Having installed solar batteries, you no longer need to worry about humongous electricity bills. Much of your consumption will be satiated with the energy stored in your batteries thus reducing your electricity bills, especially during times of peak demand.
Solar power batteries are fantastic complementary equipment for solar PV systems. If you’re planning to invest in a solar energy system or simply wish to know more about it, feel free to get in touch with VEMC by calling on 022 43436655 or emailing us at marketing@vemc.co.in.

The Impact of Energy-Efficient Pumps on Building a Sustainable Economy

by vemcoblogs - July 20, 2024August 23, 2024

Pumps shoulder a substantial portion of the fluid management burden across industries. This means they also consume significant amounts of energy. As the prices of electricity rise globally and sustainability becomes an increasingly crucial conversation, energy-efficient pumps are going to play a central role. VEMC is a leader in pumps, valves, air compressors and solar rooftop systems, and in this blog, we talk about the impact of energy-efficient pumps on building a sustainable economy.

Environmental and economic costs of inefficient pumps

Pumps come at an initial as well as a lifecycle cost. The latter is incurred mostly due to over-consumption of energy, maintenance or damage to the environment.

As most of the electricity generation continues to depend upon fossil fuels, inefficient pumps don’t just raise your electricity bills but also lead to higher emissions, greenhouse effect, climate change and resource depletion.
Inefficient pumps generate too much heat which could be dissipated in local ecosystems like water bodies, leading to undesirable changes in them.
Inefficient pumps could cause improper distribution of water, wastage and depletion of water resources.
These pumps tend to deliver lower levels of productivity, have higher chances of breakdowns, and cause business losses especially where critical processes rely directly on the pumps.
These pumps often have high lifetime costs as they are prone to wear and tear, downtime and high maintenance.
In a lot of countries where strict compliance laws for energy efficiency exist, such pumps can put owners at risk of fines, penalties and punitive action.

How energy-efficient pumps help reduce energy consumption and operating costs

Energy-efficient pumps offered by VEMC are up-to-date when it comes to meeting the demands of today’s resource and energy crunch. Here’s how these pumps fit your bill:

Higher motor efficiency: Due to better designs and lesser losses while converting electrical energy into mechanical energy, energy-efficient pumps reduce energy consumption significantly.
Bridging the demand-supply gap: Using Variable Speed Drives (VSDs), energy-efficient pumps accurately match the pressure and flow supplied to that needed, thus reducing the wastage of energy.
Better pump designs: Thanks to their improved internal pump designs, energy-efficient pumps reduce friction of internal parts and related losses.
Lower lifecycle costs: While energy-efficient pumps may come at higher initial costs, these incur lower lifecycle costs in terms of energy consumption and maintenance needs.
Compliance: Energy-efficient pumps are designed keeping in mind various compliance standards which enable owners to steer clear of penalties, and on the contrary may even help qualify them for incentives.
Environment-friendly: Energy-efficient pumps reduce the pressure on fossils leading to the emission of significantly lower levels of greenhouse gases. This pays rich dividends for the environment.

5 key benefits of installing a screw air compressor over a reciprocating air compressor

by vemcoblogs - July 16, 2024August 23, 2024

If you’re planning to buy a new air compressor, you must wonder which one suits your requirements better. Air compressors are after all a hefty investment in your operations and the decision must be made after careful planning. While both screw and reciprocating air compressors find utility across industries, the former has some well-established benefits over the latter. VEMC is the leading ELGi Screw Compressor dealer based in Mumbai, and in this blog, we take you through 5 key benefits of installing a screw air compressor over a reciprocating air compressor.

Working principle of screw air compressor vs reciprocating air compressor

First, let us look at how a screw compressor is different from a reciprocating air compressor.

Rotary screw compressors simply work by compressing air using helical screws known as rotors. This forces the air through the chambers and compresses it into a smaller space. With this mechanism, as the rotors turn, the air gets continuously compressed. Reciprocating compressors on the other hand work by using pistons which move back and forth. This reduces the air mechanically, leading to an increase in pressure.

Benefits of screw air compressors over reciprocating air compressors

Consistent output and high volume: Screw compressors operate continuously unlike reciprocating compressors. This gives a smooth output that can be crucial in tasks that need consistent air pressure. For tasks which require higher volumes of compressed air, screw air compressors are better suited than reciprocating air compressors.

Efficient, compact and silent: When it comes to energy consumption, screw compressors are more efficient than reciprocating air compressors. This helps reduce operation costs over time. Screw compressors are also more compact which makes them adaptable to various environments. They’re usually noiseless and are thus better suited for residential areas and other noise-sensitive settings.
Lower maintenance needs and longer lifespan: Screw air compressors do not have pistons, valves or any other moving parts. This reduces the levels of friction, wear and tear, maintenance needs, and downtime. Due to this, screw air compressors tend to have a longer working life than reciprocating air compressors. Their downtime is also lesser and lifespan costs are under control.
Higher quality of air: Since screw air compressors operate with sealed chambers and have better filtration systems, they tend to offer a higher quality of air as compared to reciprocating compressors.
Adaptable: Using Variable Speed Drives (VSDs), screw air compressors can easily adapt the supply of compressed air to the fluctuating demand. This saves energy and ensures efficient operations.

Due to the above-mentioned benefits, screw air compressors are used in a diverse range of industries and applications. These are usually preferred in industries like manufacturing, construction, oil and gas, food and beverage, pharmaceuticals, power generation, mining, chemicals and petrochemicals.

Importance and procedures of testing fire-fighting pump

by vemcoblogs - July 12, 2024July 15, 2024

It is important that your fire pump is reliable, performs to its best levels and has a short response time to a breakout. Prior testing of the fire-fighting pumps is therefore crucial. VEMC is a leading Kirloskar fire pump dealer based in Mumbai, and in this blog, we take you through the importance and procedures of testing your fire-fighting pumps.

Legal requirements for regular fire pump testing

In India, fire safety is mandated at various levels of governance. The National Building Code (NBC) makes a provision for fire safety through pump installation and testing in section 4. Likewise, many states have their fire safety laws which provide detailed requirements for fire safety in buildings. Even at the municipal level, fire safety bylaws provide for fire pump testing intervals, standards and compliance checks.

Importance of fire pump testing

Fire pump testing is important to ensure preparedness in times of fire emergency. It can make the difference between life and death. So here’s why testing your fire pumps is necessary:

Checking reliability: With regular fire pump testing, you can ensure the highest levels of reliability. Check for leaks, malfunctions, or any mechanical issues that can affect the pump’s performance regularly.
Performance testing: Just having a functional fire pump is not enough. Your pump should be able to deliver an adequate amount of pressure and flow rate at the time of a fire emergency.

Response time: Time is of critical importance in fire emergencies. How quickly your pump responds to a breakout could be decisive in preventing damage to property and loss of lives.
Preventive maintenance: Regular testing and preventive maintenance of your fire pumps can help unearth mechanical issues or problems that can eventually cause malfunction when you need them to work the most.
Compliance purposes: Laws across the world codify fire pump testing as an important fire safety measure. It is thus also important for building owners to carry out regular testing to meet compliance standards and avoid penalties.

Steps of testing your fire fighting pumps

Preparation: Gather the pump manual and other documents, and inform all the stakeholders about the upcoming testing to minimise disruption of operations.
Visual inspection: Visually check the pump and its surroundings for any indications of a failure. Check the valves, gauges and controls and ensure they’re in good working condition.
Electrical and control system check: Make sure all electrical circuits, switches and panels are working.
Suction piping inspection: Check the suction piping for any leaks, blockages or corrosion, and make sure it is correctly aligned.
Flow and pressure testing: Use a flow meter to check the rate and pressure offered by the pump at various points.
Operation testing: Run the pump, listen in for any unusual noise or vibration, and check its performance over a specified duration.
Shut down and inspect: Shut the pump down and check for any post-testing issues.
Documentation and reporting: Finally, record and document all the parameters tested. Prepare a detailed report including recommendations for the future.

Methods for protecting borewell submersible pumps from damage caused by sand and other abrasive particles in water

by vemcoblogs - July 8, 2024July 9, 2024

Borewell pumps find application in several tasks in households, businesses and industrial settings. However, their maintenance can be a challenge due to the abrasive nature of sand and other particles found in the water that they pump. VEMC is the leading Kirloskar water pump dealer based in Mumbai and in this blog, we talk about the methods for protecting these pumps from damage to prevent wear and tear and prolong their working life.

How sand and abrasive particles can cause damage

Wear and tear of pump components: Sand and other abrasive particles can act as sandpaper on the internal components of a pump over time, and cause gradual but significant erosion, thus reducing the working life of the pump.
Blockages: By clogging or blocking the pump intake, sand and other particulates can lead to reduced efficiency, overheating, and cavitation.
Higher maintenance costs: With a greater amount of particulates present in the water, there is a proportional increase in maintenance frequency and costs. This could be due to frequent breakdowns due to abrasion.

Methods to protect the pumps

Several measures can go a long way in protecting the pumps from damage caused due to abrasion by sand and other particulates:

Use filters and screens: Make use of filters or screens to prevent the sand and other particulate matter from reaching the pump. Choose them as per the size of the particles you’re trying to block, and clean or replace them from time to time.
Install a gravel pack: You can use a gravel pack around the pump to prevent fine sand particles from entering it.
Regular inspections: Establish a schedule for regular inspection of your pump, and clear any sand or debris accumulated. Also, look for signs of abrasion of parts and ensure timely preventive maintenance.
Proper positioning of the pump: Pump alignment and positioning can reduce the damage due to abrasion. It also reduces the risks of wear and tear between parts significantly.
Well design: Bring experts on board and consider a suitable design for the well that reduces the likelihood of particulates entering the pump.
Look for resistant material: While choosing your pumps, look for the material that has gone into making its casing, impeller, and other parts. A pump made of robust material is more likely to withstand abrasion.

VEMC pumps are designed for abrasive environments

How solar energy can provide affordable and reliable electricity access in developing countries

by vemcoblogs - July 5, 2024July 30, 2024

Developing countries often lack sources of affordable and reliable electricity. This is mostly due to weak infrastructure, geographical challenges, lack of technical expertise, and limited financial sources to build a robust electricity base. For such countries, solar energy could come as a huge boon. We at VEMC are one of the leading solar panel consultant and installers in the country, and in this blog, we see how solar energy can become a game-changer in the developing world.

Benefits of solar power for developing countries

Decentralised source of power: Developing countries often struggle to establish conventional electricity networks in their vast interiors. Solar energy on the other hand provides decentralised supply which brings communities in such parts on the grid, significantly improving their living standards.
Reduces reliance on fossils: Many developing countries, owing to their lack of electricity infrastructure, depend on fossils such as coal and petroleum for their energy. This is not just expensive or exhausting but also damages the environment. Solar energy can significantly reduce their reliance on such sources of energy, benefiting communities, towns, and whole countries at large.
Employment generation: Solar energy once established grows into a multi-pronged industry. It has the potential to create jobs in various parts of the solar value chain such as manufacturing, installation, operation, and maintenance. This can help create employment and boost the economies of developing countries.
Low-cost energy source: Developing countries are often cash-strapped which puts their energy security at risk. Over the years, the cost of solar energy has declined appreciably and solar has emerged as a cost-effective source of energy especially in tropical countries which get abundant sunlight. This can reduce the burden on end-users, communities, and businesses, while also helping preserve the financial resources and precious foreign exchange for governments.
Technology advancement: Solar energy offers an unprecedented opportunity for developing countries to advance to the next tier of technological advancement in terms of energy production. This is extremely critical with rising pressure on conventional sources of energy and their overall rising prices.
Sustainability: Conventional energy sources are often quite damaging to the environment. These do not just include coal-based thermal electricity but also hydro-power plants which are seemingly clean but come at humongous environmental and human costs across the developing world. Solar energy on the other hand is one of the most preferred sources of energy in terms of sustainability.
Buffering energy shocks: Conventional sources of energy are often prone to disruptions due to shortages of fossil fuels like coal, or natural calamities. Solar energy can act as a great cushion to prevent blackouts during such emergencies and keep at least the critical parts of the economy running.

Solar energy quite clearly is a godsend for the developing world!

Proper procedure for priming a centrifugal pump to prevent and ensure smooth operation

by vemcoblogs - July 2, 2024July 2, 2024

If you own a centrifugal pump, you would know the importance of priming it before use. It simply refers to filling the pump with a liquid to generate enough suction to operate efficiently. VEMC is the leading Kirloskar pump authorised dealer and in this blog, we talk about the proper procedure to prime your pump to prevent damage and ensure its smooth operation.

Dangers of running a non-primed pump

Cavitation: Without enough liquid for suction inside the pump, there are high risks of cavitation. This is caused by the creation of air bubbles which on bursting create tiny shock waves inside the pump body, leading to gradual internal damage over time.
Drop in performance: Without priming, a centrifugal pump tends to operate at lesser efficiency. It is unable to generate optimum pressure and flow rates.
Overheating: Without adequate fluid inside the pump, the rotating parts can get overheated. This can catalyze wear and tear, and also reduce the expected lifespan of the pump.
Damage to parts: Impellers, shafts, bearings, and seals could face excessive strain due to a lack of fluid inside the pump. This can cause severe damage to parts over some time.
Safety hazards: In some sensitive applications, not priming a pump could even lead to accidents, environmental hazards, and disruptions.

What are the different priming techniques?

Manual priming: Simply by opening the casing and suction pipe and letting the liquid flow in.
Flooded suction: By installing a pump below the level of the source of liquid, and thus using gravity to prime the pump.
Self-priming: Pumps create a vacuum to draw in the liquid automatically without any manual intervention.
Vacuum priming: Using an external vacuum pump to draw the liquid into the casing.
Recirculation: The pumped fluid is recirculated from the discharge side into the suction side. This is especially useful for low-viscosity liquids.
Using a priming pump: A separate priming pump or system is used to create a vacuum, evacuate air, and draw the liquid in.

How to prime a centrifugal pump safely

Make sure your pump is ready for priming. Check all the valves, fittings, and connections.
Check whether the pump has adequate fluid levels to cover the pump’s suction inlet.
Open the vent valve and allow the air to escape.
Fill the pump casing in case you are priming manually.
Close the vent valve once you have filled the suction line with fluid. This will prevent air from escaping.
If you’re using a self-priming pump, start the priming process at this stage.
Monitor the pump priming process throughout, to ensure proper operation.
Close the priming mechanism (if applicable) and start the pump.

How dewatering pumps manage solid waste and debris

by vemcoblogs - June 26, 2024June 21, 2024

Solid waste in water could make users wary of clogging in piping as well as pumps. But with the right dewatering pump, there is simply no cause for worry. VEMC is the leading Kirloskar pump dealer based in Mumbai, and in this blog we talk about the challenges and possibilities of dealing with solid waste and debris using dewatering pumps.

Challenges of solid waste in dewatering

Physical blockage: For starters, solid wastes like rags, wood or plastic bags can create physical blockage inside the pump, thus reducing its efficiency.
Wear and tear: With repeated passage of solid waste especially abrasives like sand and gravel, the wear and tear of pumps may increase, reducing their working life.
Pump capacity is reduced: Obstruction caused by solid wastes can reduce the capacity of the pump to displace water significantly.
Rise in maintenance costs: Repeated wear and tear can cause breakdowns and result in rise of maintenance costs over a period of time.
Higher downtime: Pumps that process solid wastes along with water always carry the risks of sudden and unexpected breakdowns. This can affect business operations that are directly dependent upon pumping.

Features of dewatering pumps that can help manage debris

While above challenges are quite realistic and can pose significant risks to your pumps, some features of your dewatering pumps can help manage the debris with ease.

Capacity to handle solids: Dewatering pumps are specially designed to handle solid wastes in water. Pumps with large impeller passages or vortex impellers can be highly useful for this.
Design features: Dewatering pumps have a unique non-clogging design (say using vortex impellers, built-in strainers and filters) which reduce the risks of clogging.
Lesser wear and tear: With their robust construction of cast iron or stainless steel, dewatering pumps can withstand wear and tear due to abrasion admirably.
Variable speed and flow: Some dewatering pumps can optimise their performance even with debris by adjusting their speed and flow. This can prevent clogging and improve efficiency.
Self-priming: Pumps that are self-primed are easy to operate and maintain especially with high debris content in the water.
Ease of maintenance: Dewatering pumps provide ease of access to their internal component parts, making it convenient to clean and maintain them regularly.

Pre-filtering water to minimise solid waste

While all the above features are a great add-on to your dewatering pumps, it is always advisable to pre-filter water before it reaches your pumps. It can add a significant layer of safety for your pumps and reduce the need for maintenance and regular cleaning, prevent system damage, and improve pump performance.

How to clear debris from your pumps

Inspect the intake visually to identify debris
Remove the debris manually while wearing protective gloves.
Flush the intake with clean water using a hose.
If the pump has intake screens or filters, clean them or replace them regularly.
Inspect pump components like impellers, volutes, seals etc.

Preventive Strategies for Dewatering in Low-Lying Areas

by vemcoblogs - June 20, 2024July 30, 2024

industrial water pumps dealers in Mumbai

If you’re dewatering in low-lying areas, be prepared for some formidable challenges. Even a moderate amount of rainfall can cause significant water logging while stormy rains can inundate the areas completely and in a very short span of time. This calls for special preparedness. We at VEMC are one of the leading industrial water pumps dealers in Mumbai, and in this blog we talk about the preventive strategies you need for dewatering low-lying areas.

Difficulties of dewatering flood-prone areas

Dewatering flood prone areas requires you to be quick on your feet. This is because even a short amount of rainfall could quickly inundate the space giving you very little reaction time.
Due to high soil saturation, it can be quite difficult to drain away the water from the low-lying area.
Low-lying areas often have a high water table which can make it quite challenging to dewater it.
While dewatering the low-lying or flood prone area, there is a risk of continuous inflow of water from the nearby streams, lakes or rivers.
Dewatering a flood-prone or low-lying area can also have serious environmental concerns as it could lead to undesirable deposition of sediments in the nearby areas.
Finally, dewatering flood-prone areas is quite a costly affair as it requires the continuous engagement of men, material and equipment.

Proactive measures for dewatering

While the above difficulties may sound rather insurmountable, it is nonetheless possible to effectively dewater a flood-prone area. This is especially true if we follow a proactive strategies like French drains and sump pumps.

A French drain is made by using perforated pipe buried in a trench that is filled with gravel. It redirects water away from an area and prevents pooling in low-lying areas.
Sump pumps are effective in areas with a high water table. It is an equipment that helps remove water logged in a sump basin.

The right pumps to choose for dewatering

Dewatering a flood-prone area is quite challenging and hence your choice of pumps must be very careful. We at VEMC offer a wide range of dewatering pumps that can help you deal with the menace of inundation especially if you’re located in a low-lying area. Our Eterna CW/BW series for instance is a market leader thanks to its powerful performance, massive capacity and robust design. It offers a head of up to 70 meters and is specially suited for dewatering trenches, pits and foundations. It has especially found enormous use during the monsoon season, and has been a favourite of municipalities, builders and mall-owners.

However, in case flooding is frequent, it is best to go with permanent dewatering systems. These provide continuous drainage using systems like:

Subsurface drainage systems
Deep well dewatering systems
Interceptor drains
Tidal gates and flood barriers
Stormwater management systems
Retention and detention ponds

Maintenance techniques for borewell submersible pumps

by vemcoblogs - June 17, 2024June 21, 2024

If you own a submersible pump, you have made a substantial investment in your fluid management operations. However, you must ensure to get the most out of it, and extend the benefits that accrue from it for as long as possible. For this, proper maintenance of your submersible pump is crucial. VEMC is the leading Kirloskar pump distributor based in Mumbai, and in this blog we talk about the maintenance of your borewell submersible pump.

Why pump maintenance is important

For starters, there are three main reasons why you must not neglect your pumps when it comes to regular and timely maintenance:

Preventing downtime: A proactive preventive maintenance of all your pumps is necessary to avoid sudden breakdowns which can cause serious losses not in equipment, money and business terms, especially if a significant part of your operations directly depends on your pumps.
Ensuring efficiency: Pumps that are maintained regularly tend to be more energy efficient. This means lower energy consumption, more savings and environment-friendly pumping operations.
Extending lifespan: By maintaining your pump regularly you can extend its lifespan by a significant period of time. This means your pump will be in service longer, and will not require replacement sooner. This saves lump-sum costs for your business and bolsters your contribution to circular economy.

Key maintenance tasks

When it comes to maintaining your pump, have a checklist of the following important tasks ready:

Check the pump overall for any leakages. In particular, check the gaskets and make sure they do not have any oil leakages.
Check if the hydraulic governors are functioning properly.
Clean the oil bulbs and level windows of the pump.
Check if there has been any damage due to excessive pump vibrations.
Inspect the suction, discharge and head of the pump.
Do the overspeed test on the pump.
Check the seal chamber for any pitting and scoring.
Prevent corrosion by applying a rust-preventive coat.
Inspect the axial float of the pump.
Check the coupling alignment of the pump.
Check the alignment of the pump shaft.
Change oil in the bearing system.

Scheduling your pump maintenance

Some issues can be checked visually and resolved on a daily basis such as clearing debris on or around the pump or checking for leaks. However, pump maintenance must also take place over a longer time horizon, that is monthly, quarterly and yearly basis. Depending upon the conditions in which your pumps operate, make a checklist of daily, monthly, quarterly and yearly maintenance tasks for your pumps. This will balance out the cost and effectiveness of your maintenance effort.

Maintaining your pump by carrying out scheduled tasks could seem quite complicated.
