Fire pump is a part of fire sprinkler system’s water supply. When the pressure in sprinkler system risers and standpipes drops below a threshold, fire pump starts to provide water flow at a higher pressure.

Powered by electric motor or diesel engine, fire pump contains below 4 main types: horizontal split case fire pump, end suction fire pump, vertical in-line fire pump, and vertical turbine fire pump. They are centrifugal pumps with high efficiency at transferring water over a wide range of flow and pressure. A Jockey pump is a small multistage centrifugal pump connected to a branch fire pipeline to maintain system pressure to a high level.
