Our hydro-pneumatic power cylinders of HPPZ-S series are manufactured in sizes from 20 to 150 KN.

Our power cylinders offer the following advantages:

Absolute air/oil separation (through use of the external actuating cylinder)
The power stroke can operate several times per working stroke (control required)
Automatic switching from the feed stroke to the power stroke
High cylinder forces without use of a hydraulic unit (hydropneumatic operation)
Install the cylinder the best way you see fit through the closed oil system (thereby creating a compact design)
No coil springs using dual-action transmitting cylinder; this prevents any risk of the cylinder being destroyed due to the spring breaking at high stroke frequencies
The highest degree of durability by using sealing gaskets from well-known German manufacturers
Visible oil level indicator on the actuating cylinder
Integrated power stroke control; this allows the cylinder to be controlled like a pneumatic cylinder via a 5/2 way valve
High-pressure connection, measuring connection and control connection
Bypass between the oil reserve and the pressure chamber (to prevent a vacuum from forming during the punching process)
