Double-acting hydraulic cylinder with built-in pump (EKPI.A)

Autonomous double-acting hydraulic cylinders with integrated pump – 850 bar force in both directions

These double-acting high-pressure cylinders with integrated pump offer uniform force development in the direction of tension and pressure – with up to 50 tons of power. Made from a lightweight, yet high-strength alloy, they are ideal for demanding applications in shipyards, heavy industry, steel construction, construction sites or mechanical and plant engineering.

Whether for welding, straightening or mounting of heavy components: These cylinders deliver precise, controllable movement with maximum reliability – completely self-sufficient, without external hydraulic source.

Speed meets precision

Equipped with a patented automatic double-current pump, the cylinders seamlessly switch from fast approach to slow working speed. This saves time and at the same time enables sensitive control during sensitive processes.

Versatile in any position

Thanks to its compact design and the 360° rotating pump lever, the cylinders can be conveniently operated in any position – whether horizontal or vertical, the integrated air filter is always optimally aligned.
