VEMC is one of the leading Kirloskar pump dealers, enabling energy efficiency with the SP coupled pumpset. These pumpsets are designed to consume 16.5% less energy while delivering highly efficient outcomes. This blog will explore how KBL’s SP Coupled Pumpset makes energy conservation easier. 

High-Efficiency Design: Made to Save

The core of the SP Coupled Pumpset’s energy-saving capability lies in its high-specific discharge. Its design ensures that the pump delivers the same volume of liquid using significantly less power than conventional pumpsets. The result? 

A 16.5% reduction in energy consumption for the same task which can lead to substantial cost savings in large-scale industrial operations.

The pumpset minimises leakage using an advanced gland-packed/mechanical seal. The seal also reduces friction loss and protects the shaft from wear and tear. Hence, the pumpset lowers energy loss and extends the equipment’s operational life, reducing maintenance downtime.

IE5 Motors: Promoting Ultra-Premium Efficiency

A key innovation in KBL’s SP Coupled Pumpset is its IE5 motor, which is classified as an ultra-premium efficiency motor. IE5 motors are the highest efficiency class available, offering a significant leap over traditional motors in energy savings. Here’s how they empower industries with energy efficiency:

  • Unlike permanent magnet motors, which can be costly and difficult to service, the IE5 motor in this pumpset is designed for ease of operation and local maintenance. 
  • The AC induction motor design does not include complex accessories or control equipment, making it reliable, affordable, and suited for various field conditions. 

Whether dealing with extreme power fluctuations or harsh environmental factors, the pumpset guarantees reliability, enhanced equipment safety, and longevity.

Hydraulic Optimisation: Contributing to Lower Power Usage

One of the SP Coupled Pumpset’s greatest benefits is its sophisticated hydraulic optimisation, which guarantees a fluid and friction-free water or liquid flow path. This modification lowers energy losses and raises the pumping process’s general efficiency. The pump’s efficiency is further enhanced by its capacity to handle high flow rates and head ranges of up to 32 meters.

Precision Engineering: For Maximum Output

Precision engineering is key to its energy-saving potential. By incorporating tight tolerances in its manufacturing process, KBL ensures the components are perfectly aligned to minimise energy wastage. 

For example, the non-clog impeller can handle suspended solids up to 40 mm, making it ideal for handling sewage, wastewater, and other challenging fluids without risking performance dips. The impeller is also coated with CED (Cathodic Electro Deposition) technology, enhancing corrosion resistance and ensuring a longer lifespan of uniform coating. 

Precision engineering, combined with the IE5 motor’s high-grade insulation, guarantees durability, even in aggressive environments.

Choosing the Right Pumpset for Your Needs

When considering a pumpset for your industrial needs, consider factors such as system size, energy goals, and cost considerations.

However, SP Coupled pumpsets are the ideal choice regarding energy conservation. Their self-priming feature, which eliminates manual priming with a foot valve, and the optimum fan design for silent operation make them a trusted solution.

The Importance of Precise Shaft Alignment in Reducing Vibration, Wear and Tear, and Energy Consumption in Pumps

by vemcoblogs -
Kirloskar pump authorised dealer

Pump systems are at the heart of many industrial operations. A poorly functioning pump degrades the performance of the system, causes extra wear and tear, and uses more energy. Shaft misalignment is among the most frequent reasons for these inefficiencies.  

VEMC is one of the leading Kirloskar pump dealers based in Mumbai, and in this blog, we discuss the importance of accurate and precise shaft alignment of pumps.

Understanding Shaft Alignment

Shaft alignment is the process of positioning the pump and its driving motor so that its rotational axes are perfectly aligned. To reduce mechanical stress and guarantee effective power transfer from the motor to the pump, this alignment is essential. The system runs smoothly and reduces vibration and energy losses when it is aligned correctly.

Maintenance and Breakdown

Any industrial system needs regular maintenance, but misalignment can significantly raise both the frequency and expense of that maintenance. Misalignment can result in excessive vibration and wear, which can create unanticipated malfunctions that halt operations and waste money in downtime. Many of these problems can be avoided by businesses performing routine shaft alignment checks before they escalate.

Let’s look into the impact of misaligned shafts on pumps.

  1. Impact due to Vibration

Vibration levels significantly increase with misalignment. The entire system shakes or rumbles while operating as a result of forces that are distributed unevenly over the coupling and bearings when the shafts are misaligned. Excessive vibration has the potential to quickly worsen and lead to serious problems like increased noise, component damage, and eventually pump failure. It is crucial to track and fix misalignment to avoid these issues.

  1. Impact due to Wear and Tear

Misalignment causes additional stress, which speeds up wear and tear on the bearings, seals, and shafts of pumps. Unnecessary friction caused by misaligned shafts might cause these crucial components to wear out sooner. This may eventually result in leaks, decreased functionality, and a shorter pump life. Correct alignment is important to prolong pump system life and prevent expensive repairs.

  1. Impact on Energy Efficiency

A misaligned pump requires more power to overcome the increased friction between components. This extra energy consumption not only increases operating costs but also contributes to the carbon footprint of the operation. As businesses increasingly focus on sustainability, reducing energy waste is crucial.  Proper shaft alignment can help businesses achieve energy savings while also maintaining high operational efficiency.

Best Practices for Shaft Alignment

Achieving precise shaft alignment requires a combination of preventative maintenance and the right tools. Here are a few best practices:

  • Regular Alignment Checks: Routine inspections ensure that misalignment issues are caught early and corrected before they lead to more severe problems.
  • Preventative Maintenance: Regularly inspect key components like couplings, bearings, and seals. Early detection of misalignment signs can help prevent extensive damage to the pump.
  • Correcting Misalignment: If alignment issues are found, adjustments should be made promptly. This may involve repositioning the pump base or motor to restore proper alignment.

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.

Dewatering in Construction

by vemcoblogs -
Kirloskar water pump dealer (1)

Excavation is a huge part of construction and water logging on the sites is a very common problem. To ensure smooth progress of the project, it is necessary that you manage the groundwater well. However, a number of different dewatering techniques are used, each suitable for a certain set of conditions and project specifications. VEMC is the leading Kirloskar water pump dealer in Mumbai, and in this blog, we tell you all you need to know about dewatering in construction.

Types of dewatering methods

  1. Subsurface drainage: 

This is a drainage method which helps remove water that has percolated into the subgrade. It is used in areas that have a very high water table or receive incredibly heavy rainfall. Subsurface drainage typically has a permeable base to remove water rapidly, a pipe collector system to convey the liquid away, and a filter layer to prevent the clogging of drainage.

  1. Sump pumps: 

This is one of the simplest and most cost-effective methods of dewatering. It involves digging pits in the drainage area to collect water which is then removed by using pumps.

  1. Wellpoint systems: 

A number of small wellpoints are installed around a site. These are connected with a central header pipe which has a vacuum function. Wellpoint systems are great for lowering the groundwater levels and facilitating construction work by creating a dry area.

Selection criteria for dewatering methods based on project specifics

The working conditions and project demands can vary from one construction site to another. The choice for dewatering methods must be made accordingly. For instance:

  • In conditions where there’s heavy rainfall, high water table or deep permeable soils, subsurface drainage can be the best option. It is also useful to drain heavy and poorly drained soils, or those that might have an impending layer at some depth, say clay.
  • In case of construction sites with shallow excavations and low-permeability, sump pumping can be the most feasible and cost effective method to remove water. However, it carries with it the risks of sudden collapse or erosion. 
  • In case of shallow excavations or fine-grained soils with low permeability, wellpoint systems can be the method of choice. It is quite cost effective and also easy to install. 

Environmental and safety concerns

Dewatering involves significant environmental and safety risks. For example, uncontrolled dewatering can deplete the groundwater of an area. Likewise, it can also cause increased sediment levels in waterways. In cases when seasonal conditions add more surface water to work sites, unmonitored dewatering can have an accidental impact on the environment.

Dewatering could be a dicey activity. To make sure environmental and safety risks are averted, builders must follow proper guidelines. For more on which dewatering method to choose for your construction site, and how to ensure environmental and personal safety, feel free to call us on 022 43436655 or email us at marketing@vemc.co.in.

How do you Address Pump Cavitation

by vemcoblogs -
Pump Cavitation
Address Pump Cavitation

To put it simply, cavitation is the creation and collapse of bubbles in a liquid flowing inside a pump. Bubbles are created due to the drop in pressure in the pump or the supply lines. This can create loud, gravelly noises inside the system. Cavitation is a serious problem for pumps as it can cause corrosion of internal components like motors, seals, and impellers. We at VEMC are the leading industrial pump suppliers in Mumbai, and in this blog, we tell you how to address pump cavitation.

Causes of pump cavitation

  1. The most common cause of pump cavitation is piping. Either the inlet pipe from the source of water is too short or too long causing pressure variations.
  2. The use of equipment like strainers or valves can also cause pump cavitation by blocking the free water supply into the pump.
  3. If the water supply is coming from a tank, less reserve liquid can cause a drop in pressure which in turn causes cavitation.

Signs and symptoms

  1. Users will usually complain of a loud sound inside the system, somewhat like gravel or coffee beans passing through.
  2. If your pump is producing lower pressure levels, it could also indicate cavitation.
  3. Cavitation can also cause unexpected vibrations not accounted for by the equipment used or liquid being pumped.
  4. Cavitation has a severe impact on your pump impeller. Any pieces or eroded parts of an impeller inside the pump system indicate cavitation.
  5. Erratic power consumption can indicate cavitation. This happens because bubbles form around the impeller or the impeller itself has begun to fail due to which the pump needs to draw more electricity to move the liquid.  

Negative impact of cavitation

When water bubbles form and explode inside the pump, these release latent heat of condensation. The pressure jet created due to this hits the nearby solid surface causing damage to it. While one or a few instances may not cause any significant impact over time the pump can get seriously damaged due to persistent cavitation. Since cavitation takes place when water enters the pump, the first component that bubbles impact is the impeller.

Preventive measures

So here are some ways to troubleshoot your pump cavitation on your own:

  1. Pump cavitation is usually caused by a drop or imbalance of pressure in the pump. This can be a result of clogs on the suction or discharge side. Make sure you check the filters and strainers for any blockage.
  2. Make sure your pump is operating at its best efficiency levels by using a pressure gauge or a flowmeter.
  3. Reconfigure your pipe designs. Pipe designs with inverted U’s on the suction side can trap air. Likewise, pipe designs with a 90 degree right before the pump can cause turbulence inside the pump. Both can cause cavitation.

water pump dealers 

Some of the biggest business concerns in modern times are costs of energy, environment, compliance, etc. Just like competitors, these factors constantly act upon your business and shape your strategy. VEMC is one of the leading water pump dealers based in Mumbai.

Top Five Reasons Why Modern Markets Demand Energy Efficient Pumps And Valves

1. Cost reduction

Due to rapid economic growth leading to a rise in consumption, there is growing pressure on our conventional sources of energy. The demand pressures are thus causing a significant rise in energy costs per unit. However, energy-efficient pumps and valves can help reduce energy bills significantly by reducing over-consumption and wastage.

2. Sustainability

Climate change has become the single greatest danger to humanity globally. Even a marginal increase in global temperatures has the potential to wreak havoc through natural disasters such as storms, floods, and landslides. To keep a check on carbon emissions, the least businesses can do is reduce the demand-side pressure on conventional sources of energy especially fossils such as coal. As your Kirloskar water pump dealer will tell you, energy-efficient pumps and valves can be a great step in this direction. By reducing energy consumption, these pumps and valves can lower our carbon footprint and contribute to a more sustainable future.

3. Compliance

Climate change is also shaping the legislative landscape across national boundaries. Governments and authorities are becoming increasingly proactive in checking pollution levels and waste of energy. Businesses are expected to comply with these legislations and regulations. Flouting these can make them liable to hefty fines, reprimands, and penalties from regulators. This makes it all the more important for businesses to use energy-efficient pumps, valves, and other equipment.

Apart from all the energy and environment-related benefits, one simple and straightforward advantage of energy-efficient pumps is optimum performance. With limited intake of energy, these pumps can provide the highest levels of productivity in terms of flow, pressure, and overall fluid handling. More efficient pumps and valves can in short enable businesses to accomplish tasks and meet business goals at significantly lower costs.

4. Eliminating losses

Control valves or bypass loops cannot be possibly used everywhere in the fluid network. These in fact are indicative of unbalanced processes or oversized pumps. As your Kirloskar pump authorised dealer will explain, pumps and valves which are innately able to control fluid flow can also help eliminate losses due to wastage of energy.

7 Common Causes of Cavitation in Pump Systems and How to Avoid Them

by vemcoblogs -
Pump Systems

If you hear your centrifugal pump making strange noises, there’s a high likelihood that it is struggling with cavitation. In simple words, this means the formation of air bubbles around the impeller. When these bubbles burst, they create high-energy shockwaves which travel across the fluid. As any Kirloskar pump dealer will explain, cavitation can cause not just noise and vibration, but also mechanical damage and performance deterioration in the long run. VEMC is one of the leading Kirloskar Pump Dealers in the country. 

In This Blog, We Explain To You The 7 Common Causes Of Cavitation And Ways To Avoid Them:

1.Insufficient NPSHA (Net Positive Suction Head Available)

When the liquid in a pump vapourises at low pressure, it causes cavitation in the pump. This happens when there isn’t enough pressure at the suction end or the pump has insufficient NPSHA. To avoid cavitation, therefore, it is important that sufficient NPSHA is available so as to ensure the liquid always remains above the vapour pressure. The pump manufacturer determines the NPSH required for each pump, and your Kirloskar pump distributor can give you all the information on this.

2. High Pump Speed Or Impeller Design

When an impeller starts to rotate at a high speed (high RPM), the flow rate and head pressure naturally increase. This causes vapourisation cavitation in the pump. To avoid it, reduce the motor speed, install an impeller inducer, or add a booster pump. Ask your Kirloskar Pump Authorised Dealer for more. 

3. Inlet Restrictions Of Blockages

This is one of the most common causes of inlet re-circulation cavitation. Regular check-ups of your pumps are necessary to find blockages. Remove any accumulation of debris that may be clogging the downstream filter. 

4. Vaporous Or Aerated Liquids

A vaporous or aerated liquid has the inherent properties of creating bubbles that can burst to cause cavitation in the pump system. As much as possible, avoid processing such liquids through your pumping systems.

5. High Fluid Temperature or Pressure Drop

High temperature or pressure drop inside the pump can also speed up the process of vapourisation of the liquid. This can again cause vapourisation cavitation. As your Water Pump Dealers would advise, it is always best to reduce (and keep under check) the temperature of your pump, its components and the liquid itself. 

6. Inadequate Npshr Margin

The NPSHR margin basically represents the safety factor by which the NPSHA must exceed the NPSHR so as to avoid cavitation. An inadequate margin means a lesser buffer and higher chances of cavitation. Speak to your Kirloskar pump dealer and ascertain all parameters to ensure the least possible cavitation. 

7. Pump Maintenance And Operation

Cavitation, like any other mechanical issue can aggravate in case the pump falls into disrepair. To ensure the pump is in the best working condition, and cavitation is minimum, regular maintenance is important. Inspect the components of the pump frequently to look for signs of cavitation.

10 Essential Things to Know About How Water Pumps Work

by vemcoblogs -

Every single day, water pump dealers are swamped by customers looking for pumping solutions. VEMC is the leading Kirloskar Water Pump Dealer based in Mumbai.

In This Blog, We Take You Through 10 Essential Things About Pumping:

Purpose of Pumps

The simple job of a water pump is to transfer water from point A to B, often with speed or against gravity.

Types of Pumps

Some of the most in-demand pumps available with VEMC –– the top industrial water pumps suppliers in Mumbai –– are:

  • Centrifugal Pumps: They boost the velocity of the liquid using the mechanical power of a rotating (hence the name ‘centrifugal’) impeller.
  • Submersible Pumps: These pumps are immersed in the medium that is to be transferred. These highly efficient pumps are available with all Kirloskar pump dealers including VEMC.
  • Fire Hydrant Systems: As soon as the fire is detected, these pumps automatically switch on and start spraying water through sprinklers. 

Key Components

Pumps have three main components –– the casing, an impeller and a motor. The casing houses and protects the pump. The impeller is simply a set of blades that is rotated by the motor.

How Pumps Create Pressure

Pumps create pressure by transferring the mechanical energy of the rotating impeller to the liquid. The action of the impeller boosts the velocity of the liquid directing it towards the outlet. 

Factors Affecting Performance and Efficiency

  • Design and type of the pump 
  • Alignment
  • Priming 
  • Wear and tear 
  • Energy supply 
  • Type and viscosity of the liquid

Important Considerations for Pump Selection

As all Industrial Water Pumps Dealers in Mumbai will brief you, your pump selection should be based on the following considerations:

  • Pump capacity
  • Fluid properties such as abrasiveness, acidity and temperature
  • Energy efficiency
  • Reliability
  • Ease of use and maintenance
  • Environment of operation

Installation and Maintenance

Before installing a pump, ensure the ground is firm and stable. Protect the pump from voltage fluctuations by earthing it. Ensure the alignment is correct to avoid unnecessary movements and vibrations. 

Maintain the pump with an adequate amount of lubrication. Having a proper maintenance regime is important to ensure regular checks and inspections. Look for damaged seals, leaks and wear and tear.

Common Issues and Solutions

Some of the most common issues that your pumps may face are:

  • Pump not primed: Make sure the pump is full of liquid before running it. If any air is trapped, the pump may not run properly.
  • Pump loses the prime: Look for leaks and remove trapped air before operating the pump.
  • Speed of the rotor is too low: Ensure adequate voltage is getting supplied.
  • Suction is low: Clean out the strainer and ensure there are no obstructions. Inspect and repair the pipeline for leaks.

Safety Considerations

  • Avoid overheating
  • Replace old and worn-out parts
  • Test for air leaks
  • Ensure proper alignment
  • Use appropriate safety gear when coming in contact with the pump

Future Trends in Pumping

  • The use of IoT technology is enabling users to monitor and operate smart pumps from a distance. 
  • New pumping technology is aimed at making the pumps more energy efficient without compromising on quality or performance. 
  • 3D printing could enable manufacturers to ‘print’ inexpensive and customised pumps and spare parts.

For starters, MSMO pumps have multiple impellers which generate more head and flow rate than a single impeller pump. An MSMO pump typically offers a head range of up to 500 metres and a flow rate of about 700 cubic meters/hour. This boosts the flow rate and makes them an obvious choice for tall buildings, especially in a fire emergency.

Efficient Energy Consumption

The power requirements of an MSMO pump are lower. Besides, with a single MSMO pump in place, there is no need to use multiple pumps at different levels of a high-rise building. As your Kirloskar Fire Pump Dealer will explain, a correctly sized MSMO pump has 7 outlets and can replace as many individual pumps. Their ring section diffuser-type construction eliminates the radial loads completely. These factors drastically reduce their energy consumption.

Reliability

The vertical execution of the pumps provides excellent mechanical stability to the MSMO pumps. This makes them highly reliable to fight fires, especially in high-rise building complexes. 

Flexibility

Kirloskar MSMO pumps can execute both horizontally as well as vertically which makes them highly reliable in times of a fire emergency. The suction or delivery piping can be fitted through 360 degrees at intervals of 90 degrees which makes fire fighting multidirectional and highly effective. 

Durability

As any Kirloskar Authorised Dealer will brief you, MSMO pumps have a high standard material of construction whether it is casing, impeller or shaft (cast iron, bronze and stainless steel respectively). These are available in both gland packing and mechanical seals. Good quality material ensures your MSMO pumps have a pretty long lifespan.

Regulatory Compliance

New global legislation, norms and standards discourage the use of pressure-reducing valves.  PRVs are often required to check the overpressurization of branches and sprinklers. However, Kirloskar’s MSMO pumps preclude the need to use PRVs making these pumps highly compliant to global standards.

Ease of Maintenance

The simplicity of design and accessibility that these pumps offer make maintenance easy and cost-effective. Kirloskar pump dealers such as VEMC in fact, offer complete pump audit maintenance services.

Cost Effective

The Kirloskar MSMO pumps are highly affordable in their class of products. Also, with these pumps, you do not need an extensive piping system or water storage tanks on the intermediate floors. This makes these pumps highly cost-effective.

  • The Current State Of Submersible Pumps

Submersible pumps operate by turning a motor’s rotational energy into kinetic energy. The simple mechanism and design have kept these pumps competitive for a pretty long time. They have traditionally been seen as highly durable. Having said that, their adaptability today is somewhat limited. 

This is because these pumps are difficult to install and massive in size which limits their portability significantly. What’s worse is that these pumps have lately begun to seem somewhat inefficient and energy-guzzling. This of course is quite problematic in the context of the sustainability, energy crisis and climate change debate.

  • Emerging Trends In Submersible Pump Technology

With advancements in material and manufacturing technologies, submersible pumps have become more corrosion-resistant, stronger, and lighter than ever before. Materials like stainless steel and titanium have significantly improved the durability and lifespan of these pumps. They are being manufactured using state-of-the-art techniques like 3D printing which has boosted their performance and reliability.

With the integration of IoT technologies in these pumps, they can be monitored and even operated remotely. The need for manual interventions through on-site visits has been limited which has implications for testing and quality management costs.

Submersible pumps are becoming highly energy efficient, in the process making businesses more sustainable. In far-off places, even solar energy has been used to run submersible pumps which is a great leap forward.

  • Innovations In Submersible Pump Design

As any Kirloskar submersible pump dealer will tell you, the introduction of lighter-weight and more compact submersible pumps has improved their accessibility. These designs make handling and installation easier and also make the pumps fit for use in distant areas or cramped spaces. 

With better impeller designs, the performance of these pumps has taken a new trajectory altogether. These pumps can now handle a vast range of liquids, operate at optimum flow and energy efficiency, and make the pump highly effective at wide-ranging tasks.

The introduction of customized pumps has also boosted the effectiveness of submersible pumps big time! Whether it is dewatering, sewage disposal or wastewater treatment, there is a special submersible pump for every task.

Centrifugal Pump Types & Common Applications

by vemcoblogs -

Centrifugal Pump

Centrifugal pumps are used across sectors in a variety of operations. These include construction, chemical manufacturing, food processing, etc. The rapidly rotating impeller of the pump boosts the velocity of fluids and pushes them out with force. A specially designed casing ensures the fluid remains constricted within, directs it to pass through the impeller and controls the flow on its way out effectively. VEMC is one of the leading Kirloskar Pump Dealers based in Mumbai and in this blog, we tell you all you need to know about centrifugal pumps.

How A Centrifugal Pump Works:

Centrifugal pumps have a fairly simple way of operating, as any Kirloskar pump dealer can brief you. These pumps have one or two impellers attached to the shaft of a rotary pump. Once the shaft turns, impellers also start to rotate. This converts the mechanical energy into the kinetic energy of the moving fluids. The rotating impellers thus move the pumped liquids along the spinning vanes, enhancing their velocity.

Basic Parts Of A Centrifugal Pump

    • Impeller is the most basic part of any centrifugal pump. These have a series of curved vanes which are usually sandwiched between two discs. 

    • On the opposite side, the impeller is connected to a motor through a shaft. The motor rotates the impeller at a high velocity, boosting the liquid’s flow rate. 

    • The casing of the pump is another important feature of a centrifugal pump’s construction. This is of two types: volute and diffuser. Both designs aim to keep the flow under a controlled discharge rate.

Types Of Centrifugal Pumps

The two major types of centrifugal pumps are:

    • Axial

    • Radial

Axial and radial pumps have only one basic distinction –– their orientation. A radial centrifugal pump pushes the liquid out through a downstream piping. On the other hand, an axial pump generates the pressure through a lifting effect of the vanes. Both radial and axial centrifugal pumps are available with VEMC –– the leading Kirloskar Pump Distributor in Mumbai.

Single-stage, two-stage and multi-stage pumps. On the basis of the number of impellers in a pump, we have 3 types:

    1. Single-Stage: 

As the name suggests, this pump has only one impeller. The simplicity of design allows for easy maintenance. These pumps are best suited for low-pressure operations.

   2. Two-Stage: 

Twin impellers present within the casing rotate in tandem and process the liquid at a high speed. It is suited for medium-head operations.

    3. Multi-Stage: 

Three or more impellers are used in these pumps to boost the liquid at maximum efficiency. These are best for high-head operations.

Common Industrial Centrifugal Pump Applications:

A number of domestic and industrial applications make use of centrifugal pumps. Some of the most important operations where centrifugal pumps find the greatest use are:

    • Sewage disposal

    • Oil and gas operations

    • Chemical processing

    • Food and beverage processing

    • Fire safety systems

Cutter Pump VS Grinder Pump: What’s Best for Sewer Systems?

by vemcoblogs -
Cutter Pump VS Grinder Pump

Your choice of pump has to depend on the operations you want to perform with it. Today, there is a wide range of options available, each pump suited for the right kind of task. When it comes to sewage pumps, two options that clearly stand out are cutter pumps and grinder pumps. Both essentially perform the same function of cutting down solid or semi-solid waste to prevent clogging. Only the technique differs. In this blog, we take you through the various aspects of both these options you need to consider before choosing it for your facility.

Clogging problems in sewage treatment

Flushable products like wet wipes, toilet paper, and scrub pads are offering a great deal of convenience to consumers these days. However, these also pose serious problems to city drainage systems as they lead to severe clogging. This can be extremely difficult to handle and can lead to an enormous amount of expenses for the repair and restoration of the drains.

Centrifugal pumps are unable to deal with this flushable material as they are designed with a rotating impeller. This has critical tolerance which makes it extremely difficult for solids to pass through. Thus, old rags, ropes, clothes, and cans can get stuck in the drains. As flushable products are fast becoming a part of our urban life, cutter or grinder pumps have also become indispensable.

Cutter pumps

These use a sharp cutting blade made of tungsten carbide that is attached to the impeller and cuts down solid or semi-solid sewage into smaller pieces of nearly 25 mm each. They can deal pretty well with rags, toilet paper, plastics, and cleaning products, thus preventing clogging of your drainage.

Grinder pumps

As opposed to cutter pumps, grinder pumps follow the mechanism of grinding the waste. A blade rotates inside a cutting ring that has multiple teeth. This way, solid or fibrous matter is ground down to finer pieces that can then be easily discharged out of the drains. These pumps can typically handle larger and more diverse materials as compared to the cutter pumps.

Cutter pumps vs Grinder pumps

These are energy efficient and low-costThese are expensive and less energy-efficient
These can deal with smaller sewageThese can cut down larger pieces and more diverse material
These are suitable for industrial operations as well as municipal useThese are best suited for large industrial purposes where sewage may be tougher and more voluminous
These have a wider head and flowThese have a narrower head and flow
Oil and grease can pose some difficulties These consume too much energy and may require screening of solids

The best choice to deal with clogging is Kirloskar’s CWC cutter pump. It is a robust, multipurpose pump that is well-suited for industrial and municipal purposes. Kirloskar cutter pump is also highly energy efficient and causes a minimum environmental impact. The maintenance is easy and highly inexpensive.

How to Calculate Total Dynamic Head for an Industrial Pump

by vemcoblogs -
TDH for an Industrial Pump

The total Dynamic Head in an industrial pump refers to the total pressure when water is flowing in a particular system. It has two parts: the vertical rise and friction loss. In this blog, we explain to you the complete calculation of the TDH. So let’s get started.

Broadly, the TDH of a pump can be calculated by following these steps:

  1. Calculate the value of the vertical rise 
  2. Find out the friction losses in the system as the water passes through the pipe and other components
  3. Add both these values to arrive at the TDH.
  • How to calculate the vertical rise:

As the name suggests, this parameter seeks to calculate the distance up to which the liquid has to rise from its starting point in the system below to the endpoint. If the liquid level at the bottom goes down, the vertical rise will naturally increase. Likewise, in case the level of liquid rises at the bottom, it has to rise over a shorter distance to reach the endpoint, and hence the vertical rise will decrease. With the increase of the value of vertical rise, the TDH also increases.

  • How to calculate friction loss:

To find out the friction loss, it is necessary to calculate the desired flow. The greater the flow going through your pipes more will be the loss due to friction. Friction loss also depends on the type of pipe in use, its vertical and horizontal length, and its schedule. You must also factor in the elbows, valves, connectors, or other components that come in contact with the liquid, and hence contribute to the friction loss. 

  • The result: Total Dynamic Head calculation:

As stated earlier, TDH is simply the summation of vertical rise and friction loss. To arrive at the TDH value, first ensure both are in the same units of length, say feet. For instance, if the vertical rise in the worst-case scenario is 25 feet, and the friction loss of the system is 6 feet, the TDH value would be 31 feet.

  • Alternative scenario:

Always considers the worst-case scenario in case of vertical rise to ensure you have sufficient amount of TDH. For instance, in the above case, if the water level never goes below 5 feet, the vertical rise will always be 20 feet and hence the TDH value will only be 26 feet.

Other Considerations When Calculating Total Dynamic Head

A few other factors also have an impact on the Total Dynamic Head. These include viscosity, specific gravity, and temperature. The specific gravity of a liquid can slightly alter the friction losses. Likewise, viscosity can significantly increase friction losses.

Unveiling the Taloja APOEM

VEMC is thrilled to announce that the Taloja APOEM (Applied Pump Original Equipment Manufacturer) pump testing facility is all set to begin manufacturing and testing the pumps in accordance with industry standards.

Let’s take a look at what is in store:

The APOEM testing unit consists of pump assembling, alignment, and dismantling units. The components of the pump are put together during the pump assembly process. And during the alignment procedure, the pump components are brought into an alignment. It is during the dismantling procedure that the components of the pump are separated.

At the pump testing platform, the pumps must be tested after complete assembly in order to evaluate their performance properly. VEMC performs pump testing on a state-of-the-art testbed that was specially designed to meet the requirements of the pump OEM market.

The Lathe machine is used to rotate a pump to perform various operations such as turning, facing, knurling, grooving, and other movements.

Further, the vertical dynamic balancing machine helps to do the impeller balancing and trimming tasks according to the reading. It balances the unbalanced impeller and grinds the unbalanced part.

At the pump paint booth, the pumps are painted in the standard colours of red or blue using the spray painting method. After they have dried, the DFT of the paint is checked as a part of the final inspection.

The newly painted pumps are then packaged in a corrugated box, loaded in a lorry, and prepared to be sent to the customer.

We have planned each activity meticulously. We’ve also established Standard Operating Procedures as the guidelines to be followed while carrying out each task, in order to ensure optimal performance and safety.

A Guide To Select The Best Water Pump For Industrial Use In India

by vemcoblogs -

We need water for a variety of essential purposes — whether it is to cook, wash, clean, or perform industrial functions. This water comes to us from the source through a pump. When you are buying a water pump, there are a number of factors to consider before identifying the right kind for your application. Before we look at what these different factors are, watch this video to get an idea about how to select a water pump:

https://www.youtube.com/watch?v=9i_c-LBEXkw&ab_channel=VijayEngineeringandMachineryCompany

Flow rate

Given in cubic metres per hour (m3/h) or litres per minute (l/min), the flow rate of the pump measures its efficiency, that is, how much water it can pump out within a certain period of time. For industrial applications, this flow rate should ideally be on the higher side, of at least 2000 litres per minute. Another reason that the flow rate is so important is that it determines the daily energy consumption as well as the durability of the pump. The lower the flow rate, the higher the energy consumed due to more prolonged usage.

Discharge head

The total height of the discharge pipe which is known as the discharge head, as well as the height from where the water is pumped, are further aspects to consider when choosing the water pump. If you need to pump the water from a significant height, make sure that you choose a higher discharge head. Additionally, the suction head capacity will determine the depth of the water being pumped.

Inlet

The size of the inlet facilitates the correct flow of the water. Too small an inlet will create friction and a subsequent loss on the pump system. So, be careful that you choose a good-sized inlet for optimal water flow and pump performance.

Water quality

It is necessary to keep in mind that different water pumps and motors, such as trash pumps and dewatering pumps, are built to work with different kinds of water. Trash pumps transfer dirty water quickly while the latter kind moves clean water between locations. When you choose a water pump for your needs, it must fit the specific purpose you require it for and should not be used inappropriately.

Pump quality

Just as the quality of the water that goes into the pump must be suitable, you must also consider the quality of the pump itself. For the maximum efficiency and compatibility, select a pump from a reputed brand and do not compromise on its quality and design. A good quality pump will last much longer, cost much less to maintain, and will consume less energy in the long run. Kirloskar is a trusted name in the industry and would be a safe bet.
