Short Description Variable Double Pumps DPVD The Liebherr axial piston double pump DPVD series is developed for the open circuit in swash plate design. These variable displacement pumps are available in nominal sizes from 108 – 108 to 165 – 165. The nominal pressure of the units is 400 bar and the maximum pressure is 450 bar absolute. The model is available as a double pump with a back to back cation. Connecting the hydraulic lines is greatly simplified by a common suction port. The inverse drive with a swivel angle of 22° is very efficient and has a very high power density. The DPVD series is available with the most common controls. Valid for: DPVD 108 – 108 DPVD 165 – 165 Features: Series D Open circuit Regulator types: Load Sensing with pressure cut-off Volume electric with pressure cut-off Pressure range: Nominal pressure pHDN = 400 bar Maximum pre
