Closed screw pump

Consisting of an external, fixed screw pump and an internal rotating pipe with welded screw coils. This type of auger does not need an elaborate screw pump bed and is ideal to retrofit existing pump shafts.

Open trough screw conveyor

It consists of a rotating core retainer with welded screw coils. The concrete shaft on-site supplies water at the upper end of the screw. The trough is built by Rehart GmbH, also a company belonging to the RehartGroup where they can rely on long-term experience in trough refurbishment.

Water lifting screw

Archimedes’ advanced principle is also used in the screw pump. It can also transport particularly large quantities of liquid or liquid-solid material up to a defined level.

Water lifting screws are increasingly used in flood protection and have recently proved their worth. The water lifting screw is also a real workhorse for many process steps in industry and waste management.
