Jockey pump

A jockey pump is a small pump connected to a fire sprinkler system to maintain pressure in the sprinkler pipes. This is to ensure that if a fire-sprinkler is activated, there will be a pressure drop, which will be sensed by the fire pumps automatic controller, which will cause the fire pump to start.

A jockey pump is sized for a flow less than the flow to one sprinkler in order to ensure a system pressure drop. The function of jockey pumps is an important part of the fire pumps control system.

Jockey pumps are typically small multi-stage centrifugal pumps, and do not have to be listed or certified for fire system application. The control equipment for jockey pumps may however carry approvals.
