Archimedes’ screw pumps operate with almost any type of fluid over long distances. Besides STR-SCRW-M include a 4-blade macerator in the pump suction that allows them to work in presence of debris.
The floating weir lip is attached to the supporting structure by means of a bellow allowing it to adjust its vertical position depending on the pump flow rate.
Building materials are sea water, hydrocarbons and UV resistant.
STR-SCRW-M-A, pump installed inside the skimmer bellow, mount the same supporting structure for all the recovery capacities, that cover a frame from 8 to 36m3/h depending on the following factors: power pack, hydraulic motor and screw pump. For the same weir lip, the lower the pump flow rate, the higher the efficiency.
