Pumps

The core parts of our adjustable systems are the pumps PA and PB. The flexible connections, which need only minimal space, as well as the possibility of attaching the pumps in any position even outside a system, gives the designer
the possibility of installing the Ergoswiss-System in very thin or complex objects.
Our pumps lift weights up to 1 000 kg quietly, and are stepless and completely synchronous – even with an asymmetrical load. They are powered by an electric drive or a hand crank.

You have the choice of two pump types:
• Pump PA to control one or two cylinders with a max. load of 300 kg.
• Pump PB to control three to ten cylinders with a max. load of 1 000 kg.

A reset force of at least 50 N (5 kg) per cylinder should be guaranteed to push the oil back into
the pump during the retraction (single acting system).
The pumps and cylinders are connected by a hydraulic hose (Ø 4 mm). The max. hose length is 8 m. The minimal bending radius is 25 mm. Three attachment holes are provided for the installation
of the pumps. The pump housing is made of an extruded aluminium sheath and is colourless anodized.

The hand crank completely disappears under the table if it is folded together. The dowel pin that attaches the crank to the pump protects the pump from overloading.
Crank radius 125 mm. A detachable crank is also available.
