What is a jockey pump controller?
These controllers are intended for use with fire pump systems. Jockey pumps are small, motor driven pumps used in conjunction with main fire pumps to compensate for minor leaks in the fire protection system and automatically maintain stand-by pressure.
What is a fire pump controller?
Fire pump controllers These are control panels containing electrical components such as circuit breaker, switches, relays and other devices dedicated to the operation of fire pumps.
What is the main purpose of 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.
Is jockey pump necessary?
A jockey pump is not required on systems utilizing a fire pump, however, due to their relative simplicity, jockey pumps are the most common method used to maintain system pressure. Since jockey pumps are not required to be listed, any pump capable of producing necessary pressure is acceptable.
What is the pressure of jockey pump?
Setting Pressure Switches City pressure is 40 psi. The fire pump generates 110 psi at churn. So, the maximum discharge pressure is 150 psi (40 + 110 = 150).
How is jockey pump pressure calculated?
Simply stated sizing is 1% of the fire pump’s flow and 110 % of the fire pump’s head. For example, if the Aurora Fire Pump System which is selected is rated 500 gallons per minute at 100 psi, the jockey pump needs to handle 5 gallons per minute at 110 psi.
How is a fire pump activated?
The turn-on for the main fire pump is a water pressure switch. When there’s a fire, sprinkler heads are going to activate and spray water. This loss of water in the sprinkler system causes the pressure to drop. When the pressure drops, the main fire pump turns on.
How does a fire pump system works?
As part of a fire sprinkler system, a fire pump receives water from either an underground water supply or a water tank, lake, or reservoir, and is powered by electricity or diesel fuel. The high-pressure supplied by the pump distributes water through the sprinkler system and hose standpipes.
How do you check a Jockey pump?
Verify start and stop settings on the pressure maintenance pump (jockey pump) by dropping the pressure in the jockey pump sensing line. After completing all inspection procedures, start the pump by slowly dropping the pressure in the controller sensing line. The pump should be run a minimum of 30 minutes.
Does a jockey pump run continuously?
Greetings Douglas, The jockey pump starts every 30 minutes or so when the pressure drops from 200 PSI to 150 PSI. It only runs for one second.
How is jockey pump calculated?
A rule of thumb for sizing jockey pump supplying underground piping is to use 1% of the fire pump rated capacity. For example: A fire pump with rated capacity of 1500 gpm. Then the jockey pump flow rate is 1500 gpm * 1% = 15 gpm.
How often should a jockey pump run?
The jockey pump starts every 30 minutes or so when the pressure drops from 200 PSI to 150 PSI.
What is a jockey pump in a fire system?
A jockey pump, also know as a pressure maintenance pump, maintains the pressure in the fire sprinkler system to avoid non-emergency starting of the main fire pump. This keeps the main fire pump from short cycling, which shortens its life span.
What is fire jockey pump?
What is jockey pump capacity?
Kirloskar Fire Jockey Pump, Max Flow Rate: 180 Lpm – 300 Lpm हेड 40 – 160 मीटर फायर जॉकी पंप, अधिकतम फ्लो रेट: 180 – 300 एलपीएम
What is HP in pump?
Horsepower is a unit of power equal to 550 foot pounds per second or 746 watts. Water horsepower is the minimum power required for a pump to move water throughout a given system, or the power that the pump would require if it were 100 percent efficient.
What kind of motor does the JP3 jockey have?
Model JP3 Jockey Pump Controller Fuseless Motor Starter • Main disconnect – padlockable – rotary type handle – door interlocked • Thermo-magnetic motor protector • Contactor Control Circuit• 24V.AC
What is a fire pump jockey pump?
Designed to control jockey pumps which maintain water pressure in fire pump serviced systems. Prevents unnecessary starting of the fire pump due to small leaks in the sprinkler system piping.
What are the jockey pump controller maintenance requirements?
Jockey pump controllers are an important part of the fire protection system. They require a minimum preventive maintenance but must be periodically inspected and their operation simulated to assure constant performance. NOTE: Qualified and authorized personnel only must do this maintenance.
