Why Use Genuine Spares in an Air Compressor

by vemcoblogs -
ELGi Air Compressor Dealers in Mumbai

The market is flooded with unbranded air compressor spare parts. If you’re an air compressor owner, you could be tempted to procure these inexpensive but substandard spares for it. While this may save you some quick bucks and get your air compressor up and running, it could prove to be rather expensive in the long run. VEMC is one of the leading ELGi Air Compressor Dealers in Mumbai, and in this blog, we tell you why you must only stick to genuine spare parts for your air compressor. 

Genuine spares mean optimal performance

Genuine spare parts are specifically designed for a certain make or model of air compressors and are therefore perfectly compatible with it. This reduces wear and tear, and risks of malfunction, while improving its efficiency. Genuine spares thus ensure that your air compressor performs at its optimum best with a minimum incidence of breakdown.

Quality and reliability

Genuine spares are made from high-quality durable material and are put through stringent quality assurance tests. The Original Equipment Manufacturer (OEM) of air compressor parts often sets high standards of quality for their parts. This means the compressor can offer greatest possible resistance to various environmental pressures and ensure utmost reliability.

Reduced safety risks

Since air compressors often operate at high temperatures and pressures, safety is always a concern for owners and operators alike. Installing non-genuine spares can put the safety of operators at serious risk due to failures and accidents. The best defence against such incidents is using genuine spare parts only. These are made by keeping in mind the highest safety standards and regulations.

Compressor warranty

Many air compressor manufacturers will void your warranty on finding out that you have used non-genuine spare parts. This is because non-genuine spares offer lower levels of compatibility and rather than improving performance can cause damage to other parts. Besides, non-genuine parts may not comply with the regulatory standards set by the OEM. On the other hand, they offer full warranty coverage for a specified period for genuine spare parts. 

Efficiency and energy savings

Air compressors have critical parameters like flow rate, pressure and consumption. Only genuine spare parts are constructed to ensure the perfect fit and maintain these parameters at optimum levels. This enables you to operate your air compressor at the highest possible levels of efficiency, thus accruing plenty of savings on your energy bills. This also means your air compressor has a lower lifespan costs and a lesser impact on the environment.
Quite clearly, if you are an air compressor user, there are multiple reasons why you must only trust a genuine spare parts manufacturer for replacement.

Crucial Role of Mechanical Seals in Centrifugal Pumps

by vemcoblogs -

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

  1. Single mechanical seal: These are the simplest mechanical seal types. These are directly exposed to the pump and fluid pressures.
  2. 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.
  3. 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.
  4. 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.
  5. 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 -
Pump Efficiency

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:

  1. Heat loss: Low-efficiency pumps lose a significant part of their energy as heat rather than hydraulic power.
  2. 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.
  3. Environmental impact: Less efficient pumps contribute to more emissions and the resulting climate change.
  4. 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:

  1. High-efficiency pumps reduce energy consumption.
  2. These pumps are more sustainable and have a lower impact on the environment.
  3. These pumps are typically reliable, have a longer working life, lower downtime and require less maintenance.
  4.  Many local and national governments offer incentives such as rebates on electricity bills if you install high-efficiency pumps.
  5. 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:

  1. Energy Star Certification by the US Environmental Protection Agency (EPA)
  2. CEE (Consortium for Energy Efficiency) Tier Ratings
  3. EU (European Union) Energy Label
  4. ASHRAE 90.1 Standards
  5. ISO 5199
  6. Hydraulic Institute Standards
  7. 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 -
fire fighting pump

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

  1. 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.
  2. 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.
  3. 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 -

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

  1. 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.
  2. Changes in flow velocity: Rapid changes in the flow velocity can lead to cavitation as it also creates regions of low pressure.
  3. 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.
  4. 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

  1. 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.
  2. 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.
  3. 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.
  4. Pump monitoring: Keep track of your pump parameters like pressure and temperature and try to maintain them within the desirable range.
  5. 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.
  6. Operational practices: Avoid sudden changes in pressure, and prime the pumps properly to ensure no air pockets are formed within the pump.
  7. 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 -

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:

  1. 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.
  2. 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 -
solar energy company

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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
