Screw Press Dewatering

Our fully automated screw press dewatering systems are for use in water, wastewater, mining, and industrial applications. With mobile pilot units and the widest range of unit models available, our screw press is the ideal dewatering solution for your application.

The Features You Want

  • Low speeds and automated control.
  • Long lifespan due to slow speeds and robust construction.
  • All wetted parts are Stainless Steel.
  • Split screen casing to simplify screw removal and minimize footprint requirements.
  • Sealing lip and screen can be replaced with screw in place.
  • Dewatering operations do not need to be suspended during cleaning. Cleaning cycle is typically once per day for 3 – 5 minutes.
  • Unattended operation requires no additional personnel or specialized training.

Engineering That Matters

  • Dewatering results similar to high speed centrifuges.
  • Fifteen models available to handle the widest range of dewatering needs.
  • Slow operating speed ensures no vibration loads.
  • Enclosed system provides odor containment.
  • Low power requirements.
  • Low / intermittent wash-water requirements.
  • Machined screens provide tighter tolerance allowing superior performance over other commercially available units.
  • High-performance screen design with largest open area ensuring maximum throughput in smallest footprint.
