Framo hydraulic fire water pumping systems, with single-stage pumps that rotate slowly during standby, offer a minimal start load and the best possible preparedness. The system uses a submerged hydraulically driven pump. This pump lifts the water to deck level, where it feeds into a pump that is directly driven by the diesel engine. Consequently, the diesel engine’s start load is kept to a minimum.
The lift pump runs continuously at low speed in standby mode, driven by a flow of low-pressure hydraulic fluid circulated by a small electrically driven pump. This ensures continuous availability and lubrication/heating of the fire water lift pump, preventing marine growth in the pump. In harsh environments far from land, such as operations in the Arctic, pump reliability is top priority.
