• Specifications

1.The pump should be installed with the oil port facing upward. The return line must be connected directly to the tank, and back pressure should be maintained below 2 bar.
2.At maximum pressure operation, each duty cycle must not exceed 6 seconds. Hydraulic oil cleanliness must comply with specifications; please refer to the operation manual for details.
3.YEOSHE provides multiple pump configurations. The pump can also be connected with other types of hydraulic pumps, using standard metric or SAE mounting interfaces.
Models up to PV320 are also available, covering applications from medium-duty to heavy-duty systems.
