DESIGN OF A BUILDING FIRE PUMP SYSTEM WITH INTEGRATED PARALLEL PUMP

Multi-storey building must be equipped with a reliable building fire extinguishing system. The existing fire extinguishing system design is not equipped with a backup pump and a jockey pump. Based on The DKI Jakarta Governor Regulation No. 92/2014 and the Indonesian National Standard, to solve this problem, a building fire pump system is designed with a combination of the jockey pump, main pump and backup pump that connected in an integrated parallel arrangement. This design allows the backup pump to automatically run due to a pressure drop in the system pipe if the main pump fails or unable to build up pressure. When a fire occurs and a lot of hydrants are used, the backup pump will automatically run to help the main pump with a signal triggered by the pressure switch.
