A multistage pump is used to generate higher pressures than is available with the use of a single impeller at maximum diameter. This is because once an impeller reaches a particular diameter the impeller side friction which increases with size decreases pump efficiency. This means it is necessary to add several impellers along the same shaft in stages called ring sections.

When stages of impellers are added the flow rate is not altered but the total head and shaft power increases proportionally to the number of stages. Each stages consists of an impeller and diffuser.

- Multistage pumps are highly efficient
- Multiple duty points can be reach through use of VSD but also multiple outlets on same pump
- Multistage pumps can be subject to vibration and cavitation

Multistage Pump for Mine Dewatering

A customer in South Africa contacted us regarding some urgent dewatering multistage pumps that were required to remove nuisance water from the mine to the surface.

ATEX Pump Guide
