Jockey Pumps
Automatic pump systems normally utilize two pumps.
One is the main fire pump which delivers large volumes of water to the
fire standpipe system in case of fire. The other is a low flow, high head
jockey pump which keeps the system pressurized during normal non-fire
conditions. Since the activation of the large flow main fire pump is triggered
by a system pressure drop, it is very important to maintain system pressure
since even normal plumbing leaks allow the system pressure to bleed down
over a period of time. When the system pressure drops to a preset level,
the jockey pump starts and charges the system back to normal pressure.
In case of fire, sprinkler heads open and fire hose connections are utilized
causing a rapid system pressure drop over and above what the jockey pump
is capable of supplying. When the lower pressure limit of the main fire
pump is reached, it starts up and provides the needed high flow for fire
suppression. The majority of the MTH regenerative turbine standard
product line is used in fire system jockey pump service, depending
upon system size.
