About
Armed with over a hundred years of experience in designing and building (waste) water treatment solutions and equipment, quality has always been our prime consideration and has earned our sound reputation. Spaans is specialized in the design and manufacture of water treatment equipment such as screw pumps and screw generators.
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 pre-assambled 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. | | |
