C1, C2, C3 Series

PWG Closed Loop Variable Displacement Axial Piston Pumps

The PWG C series is a family of variable displacement axial piston pumps for use in closed circuits. The displacement is infinitely variable by means of a tilting swash plate; the oil flow can be reversed over the neutral point. Various controls are available: manual, servo-control lever operated, electric etc. Each pump is provided with a charge pump that makes up for internal leakage, maintains a positive pressure in the main circuit and provides oil to the control system. All pumps have maximum pressure relief valves and can be supplied in a single or tandem version. Different through drive options are available for auxiliary pump mounting as well as a wide range of options: by-pass valve, pressure filter and others.
