Overview of Multistage pumps

A multistage centrifugal pump has multiple stages that are connected in series. Fluid enters the first chamber at suction line pressure and leaves at a higher pressure than when it entered. As soon as the fluid leaves the first stage, it enters the second stage, where it is subjected to further pressure increases. The final discharge pressure of a pump depends on how many stages it has, but its flow range remains constant.

Multistage pumps are of two types-horizontal multistage pump and vertical multistage pump.

CRI Fluids offers horizontal multistage pump MH Series that are most suitable for pressure boosting, utility water supply in residences, industrial washing and so on. Thermally protected single phase pump. Highly efficient pump that can handle high flow rate.

MV Series, Vertical multistage pumps from CRI Fluids are suitable for high and constant pressure applications. The design results in space saving

Frequently Asked Questions

1. What are the benefits of multistage pumps?

Multistage pumps provide a better hydraulic lift. They are flexible and can be run at a lower speed if required. The hydraulic modules, the capability to supply additional impellers, and the ability to trim those impellers allow for meeting the duty point.

2,What are the differences between a single stage pump and a multistage pump?

A single stage pump uses one impeller whereas a multi stage pump uses 2 or more impellers. Diffusers are used in multistage pumps for channelling fluid. Multistage pumps have thrust balancing devices for shaft support.
