What is a Multistage Pump?

A multistage pump is pump that consists of a number of different stages within the pumping system, where force is applied to the water. Each stage consists of one impeller as well as its accompanying diffusion components. The term “multistage” is usually used in reference to centrifugal pumps. In many cases, these pumps are referred to in terms of how many stages they contain.

I.e. A pump with four stages might be referred to as a four-stage pump, or one with 10 stages would be referred to as a ten-stage pump.

How do multi-stage pumps work? ·

The concept behind multistage pumps is fairly simple; in many industrial and fluid treatment applications, it’s necessary for fluids to be moved large distances with higher pressure. In many of these situations, the only way to achieve this higher pressure is with the use of more than one impeller. The multiple impellers are mounted on the same shaft, and the flow progresses from one stage to another, building pressure as it goes.

Common uses of Multi-stage pumps

Multi-stage pumps are most commonly used as pressure boosting systems, where application and circumstances demand constant pressure and constant flow such as in high density living – multi-storey apartment complex’s, additionally industrial applications requiring substantial pressure and flow such as wash down facilities, boiler feed systems, jacking pumps for fire hydrant systems, fire hose reel supply and irrigation systems, pipeline pigging in the Oil & Gas industry and can be driven by a number of motor options from solar powered and electric motors to diesel and petrol driven motor options.
