Types
| Compact Screw Pump | ||
| For this type there is no civil construction required! A prefabricated self-supporting steel construction with integrated inlet-section, outlet-section, trough, screw pump and drive unit is preassambled in our factory and shipped in one piece, ready for immediate installation. |  | |
| Concrete Trough | ||
| The classic and most common form is the arrangement of the screw pump in an open concrete trough where the screw, suspended between the upper- and lower bearing, rotates free from the trough with a minimal gap of only a few millimetres. |  | |
| Steel Trough Liner | ||
| Although this type requires a similar civil construction as the previous described ‘concrete trough’, there is however no screeding to be done!; instead a prefabricated steel trough liner is backfilled with concrete. |  |
