Axial piston variable displacement pump with swashplate structure for hydrostatic transmission in open circuit
- The flow rate is proportional to the input speed and displacement. The flow rate can be steplessly adjusted by adjusting the swashplate.
- Design of Slot Control Swashplate
- Stepless adjustable displacement
- Excellent oil absorption performance
- Permissible rated working pressure 350 bar
- Low noise level
- Long service life
- Driving shaft absorbs axial and radial loads
- High power/weight ratio
- Standard structure
- Short control time
- Axle drive and pump can be combined
- Swashplate swing angle indicator
- Installation location is optional
- HF oil can be used when the working parameters are reduced.

Safety instructions：

Tightening Torque:

1、 A4VSO pump is designed to operate in open circuit.
System design, installation and commissioning need to be performed by trained technicians and distributors.

2、 All hydraulic orifices can only be used to tighten hydraulic maintenance pipelines.

1、All the tightening torques listed in this sample are maximum values and should not exceed these values (maximum of internal threads in castings). Please follow the information provided by the manufacturer regarding the maximum allowable fastening torque of the fittings used.
· For DIN 13-compliant fastening screws, it is recommended that the allowable tightening torque be checked according to VDI 2230 (promulgated in 2003) in all cases.

2、The housing, especially the coil, may be particularly hot during or shortly after the operation of the pump. Please take appropriate safety measures (for example, wear protective clothing).
- All data and information provided with the product must be complied with.

3、All data and information provided with the product must be complied with.

Installation location:

1、Optional. During debugging, oil must be injected into the pump housing, and it must be filled when it is running.
In order to reduce the operating noise level, all connecting pipes (oil suction, pressure and tank drain pipes) must be separated from the tank by using flexible components.

2、It is necessary to avoid the use of one-way valves in tank discharge pipelines.
The tank discharge pipeline must be directly connected back to the tank without changing the size of the pipeline. There may be abnormal situation, please consult us in time.
It can be installed vertically and horizontally.
