Vane hydraulic pump


Sometimes the hydraulic cartridge pump is also called such as vane pump or blade pump. Hydraulic cartridge pumps are used as quiet pumps in industries. The hydraulic cartridge pump is usually operated at speeds of 1200 to 1750 rpm with an electric motor and driven by a combustion engine up to 2400 rpm and has a volume efficiency between 85 and 90 percent at the defined pressure and working speed. Despite their good mechanical efficiency, their overall efficiency is low (75-87%) due to losses due to leakages around the rotor
