Hydraulic Power Unit

Part No. 4500054

Description :

This hydraulic power unit is specially designed for clamping applications only. Special care is taken to avoid oil heating problems. This hydraulic power unit is suitable to operate double acting clamping cylinders in parallel.

Operation :

In clamping and declamping mode, after reaching the set pressure, which is sensed by a pressure switch, the direction control valve shifts to the centre position, unloading pump delivery to the tank.

In case of pressure drop, the direction control valve operates to increase the pressure to the set pressure.

The system includes all relevant electrical and mechanical accessories. A pendant with clamp and unclamp push buttons is provided along with the system.

Specifications :

Motor : 3 Phase, 1 HP, 1440 RPM.

Pilot operated check valve.
Tank Capacity : 30 liters approximately.
Useful Oil Volume : 25 liters approximately.
Working Pressure : 150 bar.
Maximum Oil Pressure : 175 bar.
Pendant Cable Length Maximum : 5 meters.
Control panel.
Length : 730 mm.
Width : 580 mm.
Total Height : 850 mm.

Notes :

Clamping time in seconds = total oil volume at clamping side of all the cylinders in cc divided by pump output (28 cc per second).
Declamping time in seconds = total oil volume at declamping side of all the cylinders in cc divided by pump output (28 cc per second).
While using a single acting cylinder on the hydraulic power unit, make sure that the return line has minimum resistance to the flow.
Special care has been taken to avoid electric shocks while designing the control panel.
