The pump intake of water is usually connected to the external water supply, whereas in other cases, it may be connected to the local source of water such as a tank, well, or body of water. The fire pump is designed to deliver water to efficiently douse fire and is required for periodic checks. They are certified by the local fire inspection agency. Hydraulic driven pumps are commonly used in spraying and liquid transfer operations. These pumps are driven by a hydraulic motor which is placed directly to the pump. Hydraulic fire water pumps utilize a submerged, hydraulically driven pump which lifts the water to deck level feeding into a pump directly driven by diesel engine. Usually there is a 70/30 load split between the direct driven pump and submerged pump. The main engine, i.e., submerged engine start load is 30% of the full load which results i...
