The simple technology of the Archimedean Screw stretches back hundreds of years and is still proving today to be an efficient, economical and safe way of pumping large volumes at fixed heads. The large passages allow the fluid to move freely with little shear, and permits the pump to manage solid laden material without the danger of blockages. The Archimedean Screw is commonly used in the handling of municipal sewage, return sludge and rainwater/floodwater management.
DID YOU KNOW… Ritz-Atro also produces hydrodynamic screws which are used for the production of electricity. The same technology working in reverse allows the natural flow of a stream to rotate the auger and produce power at very high efficiencies, and at relatively low heads.
