Single-stage centrifugal pumps refer to centrifugal pumps with one impeller, which are divided into single-stage single-suction centrifugal pumps and single-stage double-suction centrifugal pumps. Due to their high efficiency, simple structure and many other advantages, they are widely used in industrial and agricultural production and life to transport materials such as clean water, mud, acid, alkali, salt solution and liquid organic matter. And due to the different materials and structures of single-stage centrifugal pumps, they can transport different media.

Multistage pumps have two or more impellers.

The impeller plays a crucial role in the operation of a centrifugal pump. It pressurizes and transfers the fluid/liquid. Since multistage pumps have more than one impeller, the flow rate and pressure ranges in a multistage are more efficient than single-stage pumps.

Inside a multistage pump, each impeller acts like a stand-alone single-stage centrifugal pump. Hence, it works like a chain of single-stage pumps connected linearly. As the liquid moves from one stage to the next, the pressure rises while the flow remains constant.

As a result, Multistage pumps are capable of providing a flexible range of flow and head and a relatively higher degree of energy efficiency, which makes them an excellent choice for many applications.
