These light-weight but powerful two-stage pumps are particulary designed for maintenance and repair jobs. Depending on their type, they can either operate single-acting or double-acting hydraulic cylinders.
        The ideal combination of manual operated valve and remote pendant control provides the operator with ample freedom of motion and ensures a safe "holding of the load".
         The remote pendant control (1.5 m) is used to start the motor even under full load. The function for both manual valves is as follows: - advance - stop - return - With their light weight and convenient carrying handle, these pumps can be easily transported. Pumps are equipped with thermal overload protection and are supplied with hydraulic oil.
Operation of the power pump model PY-04/2/5/2 M:
The 2/2-way manual valve operates together with a pilot operated unloading valve, so that the two valve positions result in the following two control possibilities:
1. Cylinder holds pressure after motor stop.
2. Cylinder automatically retracts after motor stop.

Operation of the power pump model PY-04/2/5/2E:
By activating the push button number 1, the motor
starts and the cylinder advances. In the neutral position the pressure is held. By activating the push button number 2, the solenoid valve is activated, the pressure decreases and the hydraulic cylinder retracts.
