A10VNO A10VNO28 A10VNO45 A10VNO63 A10VNO85 Hydraulic Piston Pump R902495330 AA10VNO28DRS/53L-VSC12N00 Axial Piston Variable Pump

Structural principle: It adopts a swash - plate structure, and the piston is axially arranged relative to the drive shaft. The flow is proportional to the drive speed and displacement. By adjusting the swash - plate, the flow of the variable - displacement pump can be steplessly adjusted.

Displacement specification: According to the displacement, it can be divided into four specifications: 28, 45, 63, and 85. Among them, the displacement specifications of 28, 45, and 63 belong to series 52, and the displacement specification of 85 belongs to series 53.

Working pressure: The allowable continuous working pressure is 210bar, and the peak pressure is 250bar. The oil suction port pressure value is 0.8 - 5bar, and the housing drain oil pressure is at most 0.5bar higher than the oil suction port pressure, but not more than 2bar.

Control mode: There are two control modes, pressure control and pressure - flow (load - sensing) control, with a short response time.

Rotation direction: There are two rotation directions, clockwise and counter - clockwise (viewed from the shaft end).

Sealing and shaft extension: The sealing material is FKM fluororubber. The shaft extension of the variable - displacement pump complies with the SAE J744 standard, and the installation flange complies with the SAE 2 - hole standard.

Product features: It has a high power - to - weight ratio, a small size, and a low noise level. The pump body structure adopts the mature A10 technology and has a cost - optimized design, which is an ideal choice to replace the fixed - displacement pump.
