Multistage Centrifugal Pumps are mainly used in the mining industry for the purpose of dewatering the mines and pump the water to dams where it can then be reused again.
Multistage centrifugal pumps have multiple liquid chambers (stages) that are connected in series. The fluid then enters the 1st chamber at suction line pressure and leaves at some elevated pressure. When leaving the 1st stage, the fluid enters the 2nd stage where the pressure is increased even further.
This means that the more stages the pump has, the higher the final discharge pressure will be.
Like most pumps, a multistage centrifugal pump converts rotational energy, often from a motor, to energy in a moving fluid. A portion of the energy goes into kinetic energy of the fluid. Fluid enters axially through eye of the casing, is caught up in the impeller blades, and is whirled tangentially and radially outward until it leaves through all circumferential parts of the impeller into the diffuser part of the casing. The fluid gains both velocity and pressure while passing through the impeller. The doughnut-shaped diffuser, or scroll, section of the casing decelerates the flow and further increases the pressure.
