Product Overview :
A fire-fighting pump is a centrifugal pump which is used for pumping fire-fighting water. Fire-fighting pumps can be designed for transportable use (e. g. onfire-fighting vehicles or as portable fire pumps) or for stationary use (e. g. hydrants, sprinkler systems). Each pump shall have a circulation relief valve listed for the fire pump service installed and set below the shutoff pressure at minimum expected suction pressure. Exception: This rule shall not apply to engine-driven pumps for which engine cooling water is taken from the pump discharge.
A jockey pump, also known as a pressure-maintenance pump, is a small pump connected to a fire suppression system near the fire pump and is intended to maintain pressure in a fire protection piping system. These pumps recover pressures lost from gradual, slow pressure declines in a system due to temperature changes, trapped air escapement, or very small leaks. The jockey pump is essentially a portion of the fire pump’s control system.
