Application
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 and zero. 
Features
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.

Pressure Compensator
Control, "A" Option This control automatically varies pump displacement to meet the system flow demand for a constant system pressure.
Displacement starts to reduce to zero within 14 bar (200 psi) of the compensator setting. Power draw-off is minimized, therefore, system relief valves should not be required. 

Pressure Compensator Control with Maximum
Displacement Adjustment As indicated for "A" option above, except there is an independent screw adjustment of maximum displacement from 100% (rated) to 25%.

Details regarding the choice of hydraulic fluid     

The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in

a closed circuit the circuit temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case. Example: At an ambient temperature of X °C an operating temperature of 60 °C is set. In the optimum operating viscosity range (shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature. At no point in the system may the temperature be higher than 115 °C. If the above conditions cannot be maintained due to extreme operating parameters, please consult us.

Hydraulic fluid   

Before starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions. The variable pump A4VG is unsuitable for operation with HFA, HFB and HFC. If HFD or environmentally acceptable hydraulic fluids are being used, the limitations regarding technical data and seals mentioned in RE 90221 and RE 90223 must be observed. When ordering, please indicate the used hydraulic fluid.
