Types of Pumps: Working and Their Applications

Pump is a device helpful in transferring/moving the liquid or substance from one place to another. This device is an ultimate solution in a severe water shortage condition. Pump moves the water with the help of mechanical action by converting electrical energy into hydraulic energy. Water Pumps are generally equipped with engines to perform manual operations. Currently, the market provides various types of pumps useful for meeting different water applications. These application types are based on the kind of fluid, distance to move the fluid, quantity of liquid required, etc. Let us now see the various types of water pumps and their working principles & applications.

Types of Pumps and Their Uses:

1. 0.25 hp Water Pump - It is basically used for transporting the water from one place to another using a piping system. This device converts the input energy into kinetic energy. It moves the water from a low-pressure area to a high-pressure area. Some typical applications of 0.25 hp pumps include residential, agriculture, or industrial fields.

2. Centrifugal Monoblock Pump – This type of pump is suitable to use with freshwater/fluid that is not chemically violent towards the pump system. It is a prevalent type of water pump preferred in India. This pump uses the centrifugal force from its centrifugal electric motor to convert the kinetic energy into the fluid’s pressure head. Specific benefits of using this pump are less friction loss, simple design, high speed with low maintenance, and steady output delivery. Some of its standard application fields are the oil & energy industry, food sector, chemicals, agriculture, industrial, and civil relevant for its consistency and strength. Radial and axial are the two standard types of mono-block pumps.

3. Borewell Submersible PumpIt is mainly used for groundwater extraction in homes, hospitals, farmlands and industries. The device comprises a sealed motor and motor unit placed inside the bore dug in the earth. Borewell size, head, delivery outlet size, water type and discharge rate are essential parameters to consider when choosing this pump. Its typical applications are fire fighting systems, farm irrigation, deep water drilling, sewage handling systems, pressure boosting systems, etc.

4. Engine Driven Pumps – It works on a diesel engine to safely transfer the fluid or water from one place to another. This device pumps the fuel from the tank into the carburetor. Engine-driven pumps are applicable to work even in a corrosive environment. Standard engine-driven pump applications are industrial, agricultural, manufacturing, flood recovery and chemical operation. The two benefits of this pump are high portability and can run independently of electric supply.

5. Open-well Submersible Pump – This pump is fully submerged in water. It can be either a single-stage or multistage pump. It is generally made up of cast or ductile iron material. Horizontal and vertical are the two standard types. Open well submersible pump is mainly used for agricultural irrigation, domestic water supplies, industrial water supply and cooling water circulation systems.

6. Sewage Pump – It is mainly used to pump effluents, waste elements, etc., diffused from commercial, industrial, municipal and wastewater treatment plants. This pump is suitable for heavy-duty jobs and is mainly made of stainless steel. The pump motor pushes the waste from the impeller to the discharge pipe for diffusing the material. Sewage pump is commonly used in municipal wastewater treatment plants, buildings and private homes, etc.

7. Grease Pump – It is mainly applied in automotive and manufacturing, food and beverage, and marine and construction industries. A grease pump is also known as a lubrication pump Benefits of using the grease pumps are efficient greasing in less time, better handling feature, and cost-effective option. Air, electric, hydraulic and pneumatic are some of its common types.

8. Monoblock Pump – A mono-block pump is a mechanical device with the combination of mover and pumps fitted in a common housing part. Head size, inlet & outlet size, discharge rate and construction material are some factors to consider while selecting this pump. It is mainly used in irrigation, agriculture, water supply for buildings and public gardens, farms, civil schemes, dewatering and other industrial applications. Its unique features include easy to use, fast operation and high scalability.

9. Jet Pump – It is mainly used for pulling the liquid towards the surface. The jet pump is also known as an artificial lifting system. The system comprises impellers and a diffuser to create a vacuum within the machine. This pump is ideal for warmer climatic conditions and places with high water level grounds. Its typical applications include transferring seawater and moving wastewater to the sewer line. Advantages of using jet pumps are long functional life, low maintenance cost, and corrosion-resistant. Deep well, shallow well, convertible and miniature are common types of jet pump.

10. Piston Pump – It is generally used to move liquid, compressed gases, viscous substances or solid particles. Some of its typical applications include the transfer of water and oil hydraulics, industrial processing equipment, high-pressure cleaning and pumping of liquids. Its benefits include a wide pressure range, high controlled pressures, high performance, etc. Lift pumps and force pumps are two standard types of piston pumps.


Different types of pumps are applicable for performing dedicated functionalities and have different working principles. As discussed in this blog, users can select the type of pump based on the water supply and output needed. Users must also check the specifications while choosing the type of water pump to get the proper amount of water and the pressure. These specifications include discharge rate – flow rate measured in liters per minute, discharge head range – a vertical distance of pumping the water measured in meters, and Power – the amount of electrical power consumed by the pump when in use measured in kilowatt or horsepower. Check out these different types of water pumps available online and choose the right type for your domestic and industrial needs.
