Today’s industries are highly complex and require multiple world-class equipments to operate efficiently, smoothly, and without expensive downtime. Most industries use some sort of liquid – oil, water, or chemicals – that need to be moved from one machine to another. Transferring liquids and fluids are super tricky, and this is where industrial pumps come into the picture.
Pumps are used to transfer liquids from one place to another without any manual labour. Industries require multiple pumps and finding the suitable pumps in India that suit your needs can feel overwhelming.
Worry not, Sintech Pumps – the best pump dealers in India walk you through the different pumps and their various applications.
Classification of Industrial Pumps
Industrial pumps can be broadly classified into two categories:
Positive Displacement Pumps
Each of these categories can be further subdivided into various types:
Let’s take a closer look at each pump category:
1.Centrifugal Pumps Centrifugal pumps are one of the most commonly used pumps in India. They are robust, efficient and cost-effective. When the pump is in operation, the fluid pressure increases from the inlet to the outlet. This change in pressure drives the fluid through the system. The liquid then enters the impeller and exits via the blade. The centrifugal power generated increases the velocity of the fluid.
Vertical Centrifugal Pumps
They are also known as cantilever pumps. These pumps have an exclusive shaft but no filling containers to cover the shaft. Instead of the filling container, it has a throttle bush. This pump occupies minimal floor space and is mainly used in applications where space is a constraint.
Horizontal Centrifugal Pumps Horizontal centrifugal pumps have two or more impellers. Each stage acts as a separate pump. Each phase is housed in a similar shelter and mounted on similar shafts. A single horizontal shaft can have up to eight stages. These pumps are primarily used for various pumping services.
2. Submersible Pumps
Also known as septic, sewage or stormwater pumps, submersible pumps are among the most commonly used pumps in India. They are primarily used in domestic, commercial, industrial, rainwater recycling applications.
They are ideal for transporting sewage, rainwater, stormwater, greywater, blackwater, bore water, foodstuffs, etc. Depending on the application, submersible pumps are available in various sub-categories like low head, high head, low flow and high flow.
3. Fire Hydrant Pumps
Fire hydrant pumps are also known as firefighting pumps, fire pumps and hydrant boosters. These pumps generate water flows with very high force and are mainly used to help firefighters tackle fires. They can also be used for irrigation and other water transfers that need high forces.
Positive Displacement Pumps
Also known as pneumatic pumps and AODD (Air-operated diaphragm pumps). They are used in applications that require pumps to run continuously. It’s primarily used in applications where the power supply is erratic and unstable. Some of the standard applications of diaphragm pumps include underground coal mines, chemicals processing and food manufacturing.
2. Gear Pumps
Gear pumps are a type of positive dislocation pumps and capable of pumping at very high forces. Gear pumps can handle fluids of high viscosity. These pumps do not have any valves, and hence, friction losses are minimal. While these pumps can take high viscosity liquids, it’s not suitable for solids or harsh chemicals.
3. Peristaltic Pumps
Also known as tube pumps, these pumps are primarily used in wastewater treatment, food processing and chemicals processing. These pumps maintain a stable flow and are ideal for various viscous fluids.
4. Lobe Pumps
These pumps have various benefits like rust resistance, reliability, hygiene and high efficiency. They can easily handle fluids and solids of high viscosity. The working of lobe pumps is similar to gear pumps – the only difference is that the lobes do not contact each other. Furthermore, these pumps have spacious interiors compared to gear pumps, making them suitable to handle slurries. Lobe pumps are generally made of high-grade stainless steel and highly polished.
5. Piston Pumps
They are the final type of positive displacement pumps. They are primarily used for irrigation. They also work well for transporting thick liquids like sauces, pastry, paint, etc.
