High pressure swash plate piston pump apply for open circuit system, build-in centrifugal pump which can enhance 19% max rotation speed, mainly use for travel machine.

Driven by axial shaft, available to connect with gear pump or axial piston pump with same specification. The out flow is proportional to the drive speed and infinitely variable between maximal and zero.


1. Designed primarily for use in mobile applications.

2. The pump operates under self-priming conditions, with tank pressurization, or with an optional built-in charge pump (impeller).

3. A comprehensive range of control options is available matching any application requirement.

4. Power control option is externally adjustable, even when the pump is running.

5. The through drive is suitable for adding gear pumps and axial piston pumps up to the same, i.e. 100% through drive.
