Reunion Fire Systems Pvt. Ltd. complies with the requirements of fire authority, consultants and with reference from national building code for supplying and installing fire fighting pump set. Our standard fire pump set packages are well assembled, supplied and installed for firefighting applications in various areas including: Warehouses, High Rise Building, Factories, Residential buildings, Hotels, Commercial Buildings, Assembly Building, Institutional Building, etc. Every set is designed and selected for its specific duty, comprising one electric motor driven, one diesel engine driven for stand-by, one jockey pump for maintaining the system pressure and one sprinkler pump for sprinkler line. These pumps are controlled and operated by fully automatic, latest designed control panels (MCC). Fire pumps are connected to water source. Positive suction, negative suction and gravitational force suction are through static water tank. Engineered for excellence in performance, our standard range is wide open to suit the customer requirements. These packaged sets are backed with prompt and quick technical support.
A fire pump is a part of a fire sprinkler system's water supply and powered by electric or diesel. The pump intake is either connected to the underground/overhead static water source. The pump provides water flow at a higher pressure to the sprinkler system risers and hose standpipes. A fire pump is tested and listed for its use specifically for fire service by a third-party testing and authorized listing agency. The fire pump installations are governed under the National Building Code. Fire pumps function either by an electric motor or a diesel engine. If the local building code requires power independent of the local electric power grid, a pump using an electric motor may utilize, when connected via a listed transfer switch, the installation of an emergency generator. The fire pump starts when the pressure in the fire sprinkler system drops below a threshold. The sprinkler system pressure drops significantly when one or more fire sprinklers are exposed to heat above their design temperature, and opens, releasing water. Alternately, other fire hoses reels or other firefighting connections are opened, causing a pressure drop in the fire fighting main. Fire pumps are needed when the local municipal water system cannot provide sufficient pressure to meet the hydraulic design requirements of the fire sprinkler system. This usually occurs if the building is very tall, such as in high-rise buildings, or in systems that require a relatively high terminal pressure at the fire sprinkler in order to provide a large volume of water, such as in storage warehouses. Fire pumps are also needed if fire protection water supply is provided from a ground level water storage tank. Types of pumps used for fire service include: horizontal split case, vertical split case, vertical inline, vertical turbine, and end suction.
A jockey pump is a 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 fire pump to start. 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. Hence a jockey pump is an important part of the fire pumps control system. Jockey pumps are typically small multistage centrifugal pumps, and do not have to be listed or certified for fire system application. The control equipment for jockey pumps may however carry approvals.
Jockey pumps should be sized for 3% of the flow of the main fire pump and to provide 10psi more pressure than the main fire pump (As per Code IS 15105:2002)
