Product Description
Detailed Specifications & Features
WFS Drumless Grinder for Sewage Lift Pump Stations
The WFS Drumless Grinder represents an innovative pre-treatment solution that transforms traditional debris salvage methods in wastewater management. Featuring a unique drumless structure and dual-shaft differential speed technology, it operates at low rotation speeds to aggressively tear and squeeze tough solids—including wood, tin cans, fabrics, and small stones—into fine particles directly underwater.
This fully buried design serves as a superior alternative to traditional mechanical bar screens by completely eliminating odor overflow and fly breeding issues. Additionally, it reduces the pump station's civil engineering footprint by approximately 25%, enabling truly unattended, highly efficient operation.

Key Applications
- Underground Pump Station Screening & Crushing: Installed directly in intake channels of urban sewers and stormwater/sewage lift stations, it pulverizes intercepted debris underwater, allowing it to flow away with effluent. This eliminates high labor and transport costs associated with traditional manual garbage salvaging.
- Downstream Pipeline & Pump Protection: Applied upstream of septic tanks, biogas plants, and industrial chemical pipelines, it crushes large solid impurities to maintain stable head loss and water depths while preventing clogging and mechanical failure of downstream equipment.
Frequently Asked Questions
What specific cost savings does this grinder offer compared to traditional semi-underground mechanical screens?
Traditional screens are typically exposed above ground, requiring over-ground building construction, and salvaged debris generates odors requiring regular, costly transportation. The WFS grinder utilizes a fully enclosed, underground design that reduces civil engineering land requirements by approximately 25%. Because pulverized waste is carried away by sewage, it drastically reduces manpower, material resources, and daily maintenance costs.
Will the machine jam or stall when processing highly entangling debris like rags and plastics?
No. The equipment features a specialized dual-shaft differential structural design with outstanding self-cleaning capabilities, mechanically preventing debris entanglement and accumulation. It includes integrated overload protection, auto-cleaning functions, and heavy-duty 9-tooth or 11-tooth hard alloy steel cutter heads, ensuring safe, reliable, and continuous operation even in demanding environments.
