Series 42 Axial Piston Pumps

28/32 cm³

The pumps have been part of this tradition for more than 15 years with proven reliability for tough medium duty applications. Recently, the HC-EDC and 32cc have been added to the long list of options

was designed with many optional features in a small package size. This helps the fit in tight places and simplify circuit design..

Four displacements in two frame sizes, (28/32 and 41/51), help to cover a wide range of medium duty applications.

Two pumps can be bolted together with additional capability for auxiliary mounting. Optional housings offer increased flexibility for conversion and base model programs with many interchangeable components.
