The SPIRALIFT SLV features a vertical auger and cylindrical screen basket with 1/4 “ (6 mm) perforations. Heavy duty nylon brushes are bolted onto the auger perimeter and sweep the screen.
The SPIRALIFT SLV fits in extremely tight locations such as pump stations’ wet wells. It is typically supplied with a TASKMASTER grinder to pre-condition the solids. After the solids are reduced by the TASKMASTER grinder, they flow into the screen area. The solids are swept from the semicircular perforated screen by brushes mounted on the perimeter of the rotating auger and conveyed vertically up the unit’s transport tube. As the solids are conveyed up the screw, liquids drain back into the flow. An optional compaction zone can be provided for further dewatering.
