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?
A jockey pump is a small pump connected to a fire sprinkler system and is intended to maintain pressure in a fire protection piping system to an artificially high level so that the operation of a single fire sprinkler will cause a pressure drop which will be sensed by the fire pump automatic controller, causing the …
What is the purpose of a fire pump fire pump?
The fire pump is a vital part of a building’s fire suppression system. It is responsible for pulling water from some dedicated source—either an underground public water supply main or a water source, such as a well, water-storage tank, lake, or other body of water—into the building in the event of a fire.
Which pump is use for fire fighting system?
centrifugal pump
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. on fire-fighting vehicles or as portable fire pumps) or for stationary use (e. g. hydrants, sprinkler systems).
What is the difference between booster pump and jockey pump?
A jockey pump is a small pump which maintains the pressure in a system without the aid of any other pump. It saves starting the main pump. A booster pump raises the pressure that the main pump cannot reach in order for the fluid to be able to enter the ‘high’ pressure system.
How many types of pump are there?
There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps.
What are the types of fire pumps?
Types of Fire Pumps
- Horizontal Split Case. The horizontal split case fire pump is the most common type for commercial buildings.
- Vertical Split Case. The vertical split case fire pump is similar to the horizontal split case pump, but they take up less space because they’re vertical.
- Vertical In-Line.
- Vertical Turbine.
How does jockey pump and fire pump works?
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.
What is the difference between a fire pump and booster pump?
A fire pump services standpipes, not to be confused with a sprinkler booster pump which serves only sprinklers. Fire pumps are substantially larger than sprinkler booster pumps. Standpipes are required per BC 905 when: The building is 2 or more stories with a floor area of 10,000 ft2 or greater on any floor.
What does a jockey pump do in a fire pump?
The jockey pump is essentially a portion of the fire pump’s control system. A jockey pump is sized for a flow less than the flow to one sprinkler in order to ensure a system pressure drop.
How does a stationary fire pump system work?
Most stationary fire pump assemblies are installed with devices that automatically sense a pressure loss in a fire protection system, and start running to supply water or boost pressure in that system.
How are portable fire pumps used in wildfires?
Portable Fire Pump and hose systems are being used by fire departments and homeowners to defend homes from burning down in a wildfire. These portable gas powered fire pumps use a suction hose that draws water from a water source such as a swimming pool, water tank, or lake.
When do you need a jockey pump controller?
A pump designed to maintain the pressure on the fire protection system between preset limits when the system is not flowing water. The controller for a jockey pump shall be listed but shall not be required to be listed for fire pump service.
