Products / GEAR-PUMPS / Design version «A»
Gear pumps of design “A” (which have got the nickname “round ones”) are intended for operation in hydraulic systems of machines which are exploited at construction plants, excavation works, under extreme climatic conditions so as under enormous dustiness. Minimizing of hydraulic loads on the housing parts, ensuring comfort operational conditions for sleeve bearings through their installation in a solid assembly unit enable pumps of design “A” to hold big hydraulic loads and have great performance figures.
