For the products delivered to you, the pump direction is not selected, so you can use it directly. For single hoist purchases, the specific pump direction, such as product matching with gear pump or straight-shaft constant volume piston pump, does not need to be selected. The pump can be used for left-hand and right-hand rotation. For products matching with oblique-shaft constant volume piston pumps, you need to select the pump direction based on the rotation direction of the take-up clutch, as shown in the figure.
