Centrifugal Pump: What it is & How Does it Work


Centrifugal pumps are one of the most commonly used pumps in many applications. With the simple design, it still handles a diverse range of heads and capacities while producing a high flow rate. Today, allow Kenflo, one of the top centrifugal pump manufacturers in world, to introduce the centrifugal pump in detail.

What is Centrifugal Pump

The centrifugal pump is a mechanical device that is designed to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. During the conveying process, the fluids rapidly come into the rotating impeller along the centrifugal pump axis and get expelled by centrifugal force along the pump's circumference through the impeller’s vane tips. To meet the diverse industrial need, there are different kinds of centrifugal compressor pumps in the industry.

How Does a Centrifugal Pump Work?

Firstly, the centrifugal pump gets powered by a motor. Then the centrifugal pump converts most of the energy into rotational energy and some energy into moving fluid's energy. Second, fluid enters axially through the eye of the housing, is captured by the impeller blades, and rotates tangentially and radially outward until it exits through all circumferential portions of the impeller and into the diffuser portion of the housing.

What are the Main Features of A Centrifugal Pump?

As above mentioned, various types of a centrifugal pumps are available in the industrial market. Then the centrifugal pump is mainly divided into two types: centrifugal and positive displacement pumps by the industrial centrifugal pump manufacturers.

Compared with the positive displacement pumps, centrifugal pumps are preferred to be used in higher flows and for pumping lower viscosity liquids. Then, the centrifugal pumps have wider application than the latter.

What are the Main Applications of Centrifugal Pumps?

Centrifugal pumps are mainly used in industrial, agricultural, and domestic applications. In the water treatment industry, diaphragm-type centrifugal pumps are an important tool in treating drinking water, boiler water, swimming pool water, and wastewater. It is used for metering precise amounts of liquid. And, in agricultural applications, it is used for conveying water, solvents, organics, oils, acids, and any kind of ‘thin’ liquids.

Main Parts of Centrifugal Pump

Since you understand the use of a centrifugal pump, the author would introduce you to the main parts of a centrifugal pump that make the pump matter in many fields.


An impeller is a wheel or rotor with a series of backward curved blades or blades. It is the first place that the fluid contact the pump. The impeller has two basic designs: a volute and a diffuser. Both of them are for making the fluid flow into a controlled discharge at pressure.

Delivery Pipe:

A delivery Pipe, also known as the eye, is a pipe connecting the upper end to the inlet of the pump to the center of the impeller and the lower end is installed into the foot valve and strainer. There is a valve near the outlet of the pump on the delivery pipe. It is used for controlling the liquid flow from the pump into the delivery pipe.

Suction Pipe

One end of the suction pipe is connected with the inlet of the impeller, and the other pipe end is dipped into the sump of water. It is composed of a foot valve and strainer. The foot valve is a one-way valve that opens in the upward direction. The strainer is used for filtering the unwanted particle present in the water, in case of blockage in the centrifugal pump.

What's the Benfits of a Centrifugal Pump?

As one of the greatest multistage centrifugal pump manufacturers, we deeply know what benefits the centrifugal pump brings. In this section, the author would list the major benefits of the centrifugal pump.

Corrosion Resistance

The centrifugal pump can transfer a wide variety of fluids and get no harm from the fluids, even corrosive liquid. Then, the centrifugal pump also can offer a long long service life, because it could withstand extremely corrosive chemicals.

Energy Efficiency

Meanwhile, it does a better performance than other pumping technologies in energy efficiency. Such excellent efficiency reduces costs both in the short term and over the life of each unit.

High Versatility

With the economic development, centrifugal chemical pump suppliers also develop a wide range of sizes and models to cater to the actual needs in the production activities.

Furthermore, the multistage centrifugal pump has been launched in the market to provide solutions for multiple applications.


All in all, the Kenflo centrifugal pump plays a very important role in the current industrial day. Most activities can not be without the centrifugal pump.

Kenflo is one of the industrial-leading industrial centrifugal pump suppliers in China and is an R&D, production, and sale. With the high-level research team, Kenflo continues to launch a high-efficiency and energy-saving Kenflo centrifugal pump to upgrade the existing products in the markets.
