The 50 LPH Rexroth Aa2fm32/61w-Vsd540 Hydraulic Pump with an axial tapered piston rotary group with a bent-axis design for hydrostatic drives in open and closed circuits. In axial piston units with a bent-axis design, the pistons are arranged at an angle to the drive shaft. The pistons rest directly on the drive shaft where they generate torque depending on the pressure.
