Sauer-Danfoss PV20 SPV20 PVD20 SPV2/033 SMF2/033 M20 MF20 — hydraulic pump / motor
Sauer-Danfoss Series 20 hydraulic pumps and motors are axial piston units with a swashplate design, developed for operation within closed-circuit hydrostatic transmissions. The PV20, SPV20, PVD20 and SPV2/033 pumps feature stepless displacement control: the swashplate inclination changes in both directions from the neutral position, providing flow reversal without additional valves. The tandem version PVD20 combines two pump sections on a single shaft to supply two independent hydraulic circuits. The SMF2/033, M20 and MF20 motors are fixed displacement units designed to work together with Series 20 pumps in a unified hydrostatic system. Output shaft speed is proportional to oil flow rate, and torque is proportional to differential pressure at the working ports.
Full model range in the section Sauer-Danfoss Series 20.
