Variable displacement pump DPVG Axial piston pump

Thanks to the use of a hydrostatic cradle bearing, the axial piston pumps for the closed circuit even impress with heavy-duty loads with their high reliability and long service life. The adjustability also enables load-independent stability of the driving mechanism.
