Water pumps for diesel engine

Concentric Pumps Ltd has added a water pump to the fuel lift and oil pumps it manufactures for the DEUTZ 2012 and 2013 Series diesel engine. The new pump incorporates a complex, high-pressure body in die-cast aluminium, containing thermostat housing, radiator inlet feed and bypass feed, as well as the unitized bearing assembly, mechanical seal and outlet volute scroll. The impeller is a one-piece, open grey iron casting with vane tips machined to aid optimised leakage. The pump is driven by a poly vee belt and its rated performance is 295LPM at 25bar. Although currently manufactured by Concentric in Birmingham, production will eventually be transformed to the sister plant located in Pune, India. The oil pump is incorporated into the engine’s front cover and is remotely driven off the crank gear, a solution which improves durability and reduces power losses when compared with the predecessor engine’s “round the crank” oil pump. The 2012 and 2013 engines are liquid-cooled 4 and 6 cylinder engines incorporating DEUTZ’s DCR® common rail fuel system and are available in a range of formats for agricultural, construction equipment and truck applications.
