Pump Curve:

The main purpose of the jockey pump is to maintain the water pressure within the pipes within a certain range when

there is no fire so that the sprinklers do not randomly go off. The jockey pump also ensures that pressure in the pipes

is maintained at normal pressure by refilling water into leaking pipes. In case of a fire break out and the pressure significantly

drops, a jockey pump cannot keep up, and the low pressure will trigger the fire pump to start pumping water.

Additionally, the jockey pump prevents the fire sprinkler system from being damaged whenever the larger fire pump begins

sending water through the system. If a fire system lacks a jockey pump to keep it pressurized, the system will develop relatively

low pressure. This can lead to damage on the system as a result of the sudden change in pressure when the fire pump begins

pumping water.

Any jockey pump consists of three components that include a motor, a controller and a pump. The two major types of jockey pumps

are regenerative turbine pumps and centrifugal pumps. The centrifugal type is less energy efficient but requires minimal maintenance

than a regenerative turbine pump. On the other hand, a regenerative turbine pump can generate high pressures with little power, but

this can create excess pressure in the system. This therefore means that it requires more maintenance.
