Horizontal Multistage Centrifugal Pumps for High Head Applications

A stainless steel cast horizontal split multistage centrifugal pump is displayed.

In horizontal multistage centrifugal pumps, the motor drives the impeller on the shaft to rotate quickly and create a centrifugal force. Under the action of the centrifugal force, the liquid in the chamber flows from the center of the impeller along the channel between vanes and splashes around, making the pressure and speed of the liquid increase as well and fluid passing through the channel on the pump bowl is directed to the next impeller. In this way, the liquid passes through all impellers and pump bowls step by step, making the pressure and kinetic energy of the liquid greatly enhanced. In the end, a certain head is obtained. The head distance of the multistage centrifugal pumps can be adjusted by increasing or decreasing the number of impellers to meet different requirements and suitable for more applications.

It is widely used in air conditioning systems, cooling systems, industrial cleaning, water treatment, aquaculture, fertilization/metering systems, environmental applications, etc.


  • High efficiency and energy saving, attractive appearance, a wide range of performance and a long lifespan.
  • Simple structure, easy installation and maintenance, small footprint, stable operation with low noise and vibration.
  • It can convey corrosive liquids, petroleum, hot water and media with wear-resistant materials.
  • The motor is added with a rain cover and can be used outdoor directly without building pump houses, which greatly saves the construction cost.
  • Shaft seal adopts hard alloy mechanical seal, reliable sealing, no leakage and small mechanical loss.
