Hydraulic Pumps and Motors

For more than 30 years, Liebherr has been developing and manufacturing a variety of axial piston units with swashplate design. The pumps and motors can be supplied for use in open or closed hydraulic circuits in a wide range of different designs and sizes for maximum pressures up to 500 bar. In China, Liebherr axial piston units are especially sought after by various top-class manufacturers of construction and special equipment that use them for example for driving travel drives in crawler vehicles. Other possible applications are the hydraulic drive systems of winches and slewing gearboxes that can be found in cranes, mobile and crawler excavators, duty-cycle crawler cranes, drilling rigs and other machinery.

Liebherr hydraulic components reveal their full potential when used in a diesel-hydraulic driveline or a multi-circuit transmission. The diesel engines, splitter boxes, hydraulic pumps and motors are optimally matched to form a complete system with high overall efficiency. A full range of pilot control devices and valves are also available.
