Caratteristiche e vantaggi

The ideal combination of manually 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 ‒ hold ‒ 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 PY-04/2/5/2E:
By activating push-button number 1, the motor starts and the cylinder advances. In the neutral position the pressure is held. By activating push-button number 2, the solenoid valve is activated, the pressure decreases and the hydraulic cylinder retracts.

Operation of the power pump PY-04/2/5/2M:
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:
Valve handle position 1: Cylinder holds pressure after motor stop.
Valve handle position 2: Cylinder automatically retracts after motor stop.
