Unveiling the Taloja APOEM

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.

How Does a Dewatering Centrifugal Pump Work?

A dewatering centrifugal pump works much like a regular centrifugal pump, but with one distinctive difference. This type of pump is built with a special feature that allows the fluid passing through it to be controlled and maintained in its movement. Let’s explore what this means and how a dewatering centrifugal pump does this.

What is a dewatering pump used for?

A dewatering centrifugal pump, just as the name suggests, is primarily used to remove water from a particular place and transfer it to another location. A dewatering pump finds several uses across industries including construction, mining, mills, and municipal operations. Any place that needs to be kept dry and clean, such as roads and worksites, will benefit from having a dewatering pump to work with. During the monsoon season especially, a dewatering pump comes in extremely handy thanks to its effective flood control, inland wastewater management, and prompt drainage functions.

How does a dewatering pump work?

A dewatering centrifugal pump actually functions as any other pump does. Just like a centrifugal pump, the dewatering pump makes use of an impeller that has a blade to start and keep up the movement of the water. The fluid goes into a smaller part of the impeller called the impeller eye. The flow of the water is then collected from here and directed to the diffuser, which is a discharge nozzle that is shaped like a cone. This is when the velocity of the water is decreased and the energy of the water flow is changed to pressure energy.

After the above process, the water is then removed from the pump at an angle of 7 to 10 degrees for optimal efficiency. This is the stage of dewatering. To help this process along, usually, an electric motor is used. However, some pumps may use different types of motors.

Special features of a dewatering pump include a robust and compact design, light weight for portability, high fluid capacity, and high abrasion resistance to enable the most efficient handling of muddy water and slurry.

Dewatering centrifugal pumps are also easy to operate and because they are usually installed above the source of water and a ground level site, they are also quite easy to access.

Today, there are dewatering centrifugal pumps available in the market that offer extremely high performance, durability and are very reliable. Many top brands are also providing quality maintenance services. Make sure to select one that offers hassle-free servicing of parts. This will minimize the possibility of downtime and ensure that your dewatering centrifugal pump continues to function at peak efficiency levels.

What does it mean if your pump is self-priming?

In several applications that require liquid to be pumped, the pump must be kept above the level of liquid. This lets air into the line, which can often create issues like overheating and pump failure. To avoid this from happening, a self-priming pump is used to empty out the air before moving the fluids. 

A self-priming pump is like other centrifugal pumps but is built with an outer casing that contains the fluid being pumped. The rotation of the impeller in this casing creates an area with low pressure at the impeller’s eye. This causes the fluid, along with the air, to get pushed up into the pump through the line of suction. Through its motion, the self-priming pump causes the air to separate from the fluid and get released from the casing. When all of the air has escaped, the pump allows the fluid to flow. Thus, a self-priming pump essentially removes any air pockets from the fluid to ensure smooth delivery by the pump. 

The main difference between a self-priming pump and a regular centrifugal pump is that there is no need to physically prime the former type, as its extra in-built mechanism is designed to do just that.

Practical uses

A self-priming pump can be used for anything that requires a standard centrifugal pump. This can include pumping water, sewage waste or other industrial applications. 

It is important to choose the right kind of pump for the task at hand, as well as the correct sized pump that matches the flow and head. Then, a net positive suction head (NPSH) calculation must be conducted to make sure there is adequate atmospheric pressure to sustain the required flow. Lastly, the speed of the pump must be high enough to be able to prime itself. The size of its line of suction too must be selected carefully.

Advantages of a self-priming pump

Because self-priming pumps are installed above the fluid source, the infrastructure needed to set them up is relatively less. They are easy to access due to their ground-level location. Maintenance and repair too, are simpler to conduct on a self-priming pump than on a regular centrifugal pump.

Self-priming pumps can handle a variety of liquids as well as slurries and suspended solids. They are also ideal for frequent pumping operations, as the steps involving pump priming at the start are eliminated. As well, they use less power and time to run than other centrifugal pumps. Self-priming pumps are also safer to operate, as hoists or cranes are not required for their use.

Limitations of a self-priming pump

Self-priming pumps have a limited suction lift. There are limitations in the NPSH and fluid temperature and can cause a loss of friction in the line of suction.

The Importance of Reading a Centrifugal Pump Curve

A centrifugal pump is used to transport fluids by converting rotational kinetic energy into hydrodynamic energy. It finds common applications across the food and beverage, dairy, and pharmaceutical processing industries. Reading a pump performance curve is important when choosing the pump that best fits your requirements.

A pump performance curve predicts the performance of a pump in terms of its flow and pressure head and being able to read it is imperative to a pump’s performance in the long term. Also, when selecting a centrifugal pump for a new application, you need to consider its composite curve so that its performance matches the one that is most suitable for the system. Generally, a composite curve consists of pump performance and horsepower curves, as well as the required NPSH (Net Positive Suction Head).

A centrifugal pump passes energy onto the fluid and possesses certain flow and head qualities. The pump needs to overcome a necessary level of pressure, and this is what determines where the performance point should be on the curve, and how much flow will be produced. The value of the pressure is inversely proportional to that of the flow. As pressure increases, flow decreases. This shifts the performance point to the left of the pump curve. Conversely, as pressure decreases, flow increases, and the point shifts to the right of the pump curve.

As a rule of thumb, when analyzing a pump curve for a new requirement, it is best to stay as close to the BEP (Best Efficiency Point) as possible. This is the operating point on the performance curve that shows the highest efficiency point for the pump’s impeller diameter. 

There are 8 main pieces of information that you will need to be able to identify on a centrifugal pump curve. They are as follows:

1. Title Box

This contains the pump model, size, speed, and other characteristics of the pump. 

2. Flow

The horizontal axis of the pump curve indicates the flow, so identify the amount needed from the pump.

3. Head

The vertical axis on the pump stands for the head. 

4. Impeller Trim

In some cases, performance points cannot be met with the maximum impeller size alone. This is why centrifugal pumps accommodate trimmed impellers. On the pump curve, the impeller diameters are to the left and the performance for each trim is represented as a bold line across it.

5. Horsepower

The horsepower is displayed as a dotted line across the pump curve.

6. NPSHR

Net Positive Suction Head Required (NPSHR) is the minimum amount of pressure on the suction side of the pump to overcome losses in pump entrance. (This is not to be confused with Net Positive Suction Head Available or NPSHA.)

7. Efficiency

On the pump curve, the efficiency is the ratio of energy delivered by the pump to the energy supplied to the pump. The higher the efficiency, the less energy required to operate for a specific performance point. Pump efficiency numbers of 60-80% are normal.

8. Minimum Flow

A centrifugal pump needs a minimum flow moving through the pump to dissipate the heat that is generated. On the left side of the curve, the minimum flow is indicated by a vertical bold line. Operating to the left of the minimum flow line is detrimental to the shelf life of the pump and is not advisable.

How Does Water Pump Contribute As A Back-Bone For Industrial Sectors

All pumping equipment is intended for one purpose, and specifically, for pumping water. They can be used in communal systems, in industry, and even in everyday life. For example, you can bring the installation of a mechanism for pumping wastewater in private sewer systems. Industrial water pumps are more complex. It’s hard to imagine how, presently, the supply and pumping of water can be done without a centrifugal pump. After all, pumps play a crucial role in this process.

In the world pumps, there are various types like Vertical Inline Pumps, Multi Outlet Pumps, and Vertical Split Casing Pumps. This is since it is possible to supply water in different ways, and not only water can be supplied and pumped out, but also other liquids.

It is essential to choose the right pump, in particular when selecting water pumps. For example, centrifugal water pumps or external circulation pumps. The only question is which pump and why.

When choosing a water pump, you can be guided by many criteria, since the choice of products is large, but more important criteria that will prompt the right choice of pump can be:

– Scope

– Tasks that the pump must fulfil

The scope of pumps for water can be domestic and industrial. If water pumps are needed for an enterprise (production, non-production), institutions, or other similar fields, it is necessary to choose water pumps in the industrial category.

Centrifugal pumps are dynamic hydraulic machines and are characterized by low cost in contrast to other devices. The simplicity of design, reliability in operation have led to their wide distribution in various industries. The advantages include continuity of fluid supply, high efficiency and reliability, and ease of automation control. Industrial centrifugal pumps available in India are used in water supply, heat power engineering, chemical, and nuclear industry.

The necessary pressure is created in the pump due to the centrifugal force when the impeller rotates. Inside the housing, the impeller is rigidly mounted on the shaft. When the impeller rotates, a centrifugal force appears, and a vacuum appears in the central part, and pressure increases on the periphery. Therefore, the liquid is pushed into the pressure pipe. Most pumps are driven by an electric motor, which can be located in one housing with the pump unit. Such an electric centrifugal pump has compactness and high efficiency.

Centrifugal pump is divided into several types, depending on the number of stages, the flows flowing along with them, as well as the conditions for liquid drainage, drive method, shaft location, and purpose. For example, a surface centrifugal pump is used to organize water supply from open sources and is installed above the surface of the pumped liquid. The working chamber must be filled with liquid before starting.

To date, the market is simply clogged with pumping equipment. This gives a certain advantage for buyers who can choose for themselves. But you must have knowledge of how the pump is used and its maintenance. Furthermore, getting the ideal type of pump is essential.

Difference between Magnetic Driven Centrifugal Pump & Mechanical Seal Centrifugal Pump

It’s undoubtedly a difficult choice to make between a magnetically driven centrifugal pump and a mechanical seal centrifugal pump! To save you some time and constant Google searches, let’s give you a gist about the main comparison between the two: 

  • Sealing the fluid

In the sealed centrifugal pumps, the presence of a mechanical seal prevents fluid leakage even while the water pump is in operation. On the other hand, magnetic water pumps do not require a seal since it has a containment shell at the end that ensures a safe enclosure for any leakage to happen. 

  • Maintenance cost and life

In sealed centrifugal pumps, there is a continuous movement between the parts which are in close contact with each other. This arrangement results in easy wear down of the elements and hence, constant maintenance costs. But, because the magnetic submersible motors do not contain any seal, there’s no need for replacements, which costs less. 

  • Application of fluid types 

The mechanical centrifugal motor is capable of pumping out some hazardous fluid, but there’s always a scope for leakage there. Whereas, magnetic pumps due to their inherent design are comparatively safer for hazardous liquids as there is zero scope of leakage. Also, hazardous liquids are generally more expensive and require safe use, which proves magnetic pumps to be more effective for the purpose.
