The Liebherr axial piston pump DPVP series is developed for the open circuit in swash plate design as a parallel pump. The variable pump is available in nominal sizes 108 – 108 and 165 – 165 cm³. The nominal pressure is 400 bar and maxi-mum pressure 450 bar.

Special features of the DPVP:These pumps are specially designed for excavator applica-tions. Due to an integrated gear, a downspeeding to fullfill higher emission standards is possible. To obtain higher ma-ximum speed and flow for size 165 – 165, an impeller version is also available if required. Thanks to the inverted piston de-sign with 22° swivel angle, high efficiency and power densi-ty are obtained. The DPVP series is available with the most common controls.

* Dimensions may vary according to configuration and additional equipment (installation drawing on request).

Note:DPVP pumps can be used in single or twin circuit systems. Integrated gear pump for control circuit oil (24 cc) standard on output II, other versions on request. Direction of rotation of output: right for variant SAE-1 and left for variant SAE-2.Through-drives to output I and/or output II are possible. Different transmission ratios are possible. Additional data on request.
