Product features

◉ Flow rate infinitely adjustable: Flow rate is proportional to the drive speed and displacement, stepless variable control is realized by adjusting the swashplate inclination, fast response speed.

◉ Energy efficient design: Constant pressure/constant flow control mode saves more than 30% energy compared to dosing pumps, significantly reducing energy consumption.

◉ High pressure load capacity: Rated working pressures up to 280 bar, peak pressures up to 350 bar for high loads.

◉ Durability and longevity: The helical disc bearing adopts ‌ hydrostatic unloading technology ‌ and is equipped with ‌FKM fluororubber seals ‌, which significantly extends its service life

◉ Excellent oil-absorbing properties: Double shell drain port design, strong anti-cavitation ability, adapt to low suction pressure environment.

Note on labeling:
1) Values apply:			2) The application scope is within the necessary minimum transmission speed and the maximum allowable transmission speed
When the absolute pressure Pas at the oil suction port S is 1 bar			It is effective for external excitation (for example: 2 to 8 times the rotation frequency of a diesel engine, and the rotation frequency of a universal joint shaft).
Vopn=16~36mm²/s In the optimum viscosity range:Vopn=16~36mm²/s			The limit value is only applicable to single-stage pumps
Application of mineral oil-based hydraulic fluids			The load capacity of the connecting components must be taken into consideration
Notes:
Exceeding the maximum allowable value or falling below the minimum allowable value may result in the loss of function, shortened service life or complete damage of the axial piston pump.
It is recommended to check the load through testing or calculation/simulation and comparison with the allowable values.
