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.
