High pressure plunger pump
※ General specifications
Design |
Swash plate axial variable piston pump |
Rotation direction |
Clockwise, counterclockwise |
Pipeline connection |
Main oil port: ISO standard, split flange oil port Other oil ports: SAE straight thread oil ports with O-ring seals |
Recommended installation location |
The installation position is arbitrary, and the recommended position is that the control module is located on the top or side of the pump. The top is preferred. The input shaft is allowed to be installed vertically. If the input shaft is facing upwards, a housing pressure of 1 bar must be ensured during operation. The housing must always be filled with hydraulic oil. When connecting pumps, it is recommended to use the pump with the highest power as the front pump |
