Water Pump Types and Applications

If we reside in a city or town, we almost don’t think how the water is supplied to our residents every day. Small villages also frequently supply a set-up of pipes to transfer water for every home within the region. All we require to recognize is how to open the valve at the sink. Because the internal working is not visible, and the water supply is not dependent on the neighbors down the road. Every home has owned well and electromechanical system to draw the water from well and supply to the home. This article discusses an overview of the water pump and its working, types and their applications.

What is Water Pump?

The water pump can be defined as a pump which uses the principles like mechanical as well as hydraulic throughout a piping system and to make sufficient force for its future use. They have been approximately in one structure otherwise another because of early civilization. At present these pumps are utilized within a wide range of housing, farming, municipal, and manufacturing applications.

Water Pump Working Principle

The working principle of a water pump mainly depends upon the positive displacement principle as well as kinetic energy to push the water. These pumps use AC power otherwise DC power for energizing the motor of the water pump whereas others can be energized other kinds of drivers like gasoline engines otherwise diesel.

The water pump is a portable device and can be applied in several household applications. These pumps are used for pumping the huge amount of water from one place to another. The main purpose of a water pump is versatile. A quality pump which can be selected carefully may be perfect for draining water from a low flooded region, refilling the swimming pool, and bathtub, circulating pesticides otherwise fertilizers.

The collection of water pumps are very large, therefore, while selecting a strong and consistent one, one should think about the requirement.

Types of Water Pumps

Water pumps are classified into two types namely positive displacement and centrifugal. These pumps are mainly designed for supplying water from one location to another constantly.

Centrifugal Water Pump

Centrifugal pumps are designed with a rotating impeller which can be used for supplying the water into the pump and force the discharge flow. These pumps come in several types which includes trash, submersible, and standard models. By using these pumps, all types of liquids can be pumped with low-viscosity. And also these pumps work fine with thin fluids & gives high flow rates.


These pumps are applicable in several applications like building as well as the water system. These pumps are used to provide water supplies for buildings and well-matched with pneumatic systems where the no-suction lift is necessary. The main purpose of these water pumps is to pump water from wells in homes & to increase water pressure in intake lines. Centrifugal pumps offer a nonstop pressure supply for fire guard systems, and they can supply like sump pumps in horizontal otherwise vertical configurations.

Centrifugal pumps are horizontal to numerous general problems. These may require liquid circulation to stop overheating which is caused by low supplies. These types of pumps must be prepared to work properly. As a head of the positive suction system is very less while selecting the pump, it can consequence to cavitations, a situation wherever air bubbles form close to the impeller, then leads to shock signals within the water pump. At last, wear of the impeller of the pump can be degenerated by delayed solids within the fluid.

Positive Displacement Water Pump

Positive displacement pumps supply a set amount of flow throughout the mechanical contraction and development of a stretchy diaphragm. These pumps are applicable in several industries that control high-viscosity fluids wherever responsive solids may be there. These are suggested for the applications wherever a combination of high pressure and low flow is required.


Sometimes, these pumps are also called rotary pumps, and these are very competitive because of the fact that they remove air from the lines and therefore get rid of air leakage. These are also efficient while dealing with high-viscosity fluids. The main disadvantage of these pumps is that they need extremely little clearance among the revolving pump & the external edge of the unit. Consequently, the revolution must happen at extremely slow speeds. When the water pump is functioned at high speeds, then the fluid can ultimately decrease the efficiency of the pump.

How to Choose the Pump?

There are some factors need to be considered while selecting the pump that includes the following.

Material: The pump material should be weather-resistant for exposed uses.

Power: The power of the pump mainly includes horsepower & the flow rate.

Type of Fuel and Motor: The motor and fuel of the pump should be electric motor, gas, hydraulic, diesel, otherwise manual.

Head: The total head expulsion, otherwise utmost pump power, appropriate for the proposed application

Applications of Water Pumps

Water pumps are used for dewatering reasons decreasing the downtime from huge rain events. The common applications of these pumps include buildings, wells, boost application, circulation of hot water, sump pits, protection of fire systems, etc

Thus, this is all about water pumps which are frequently used in construction fields for removing surplus water as well as dewatering. Because of heavy rains, the flow of water can increase & water pumps let you supply the water rapidly to reduce downtime. These pumps are appropriate for applications like electric, hydraulic, gas-powered, and otherwise manual.

These pumps are vast addition to our life because they make possible a huge variety of industrial, agricultural and household tasks. But, the variety of water pumps in the marketplace is so adaptable and plentiful that selecting the correct pump appropriate for your requirements is challenging.
