Overview
When ordinary submersible sewage pumps keep clogging on textile fibres, hair or sanitary products, the answer is a cutting head — a hardened blade at the impeller inlet that shreds solids before they hit the impeller. The WQK series adds a single cutter; the DGWQ series adds a patented double cutter (inner and outer blades) plus an optimised anti-clog casing and a higher-head hydraulic, reaching up to 80 m — enough to push processed effluent straight to the top of a building or a distant collection point.
High-grade ductile-iron impeller, hardened-alloy cutter disc, SS304 shaft, dual mechanical seal with oil-filled chamber.
WQK vs DGWQ
- WQK — single cutter, 8 – 50 m head, price-competitive.
- DGWQ — inner + outer double cutter, 15 – 80 m head, adjustable outer-cutter gap for wear compensation. Choose when the customer has had fibre jamming problems or needs to push higher.
Typical Applications
- Livestock / poultry farm effluent
- Textile and apparel wastewater
- Meat processing wastewater
- Hospital and hotel waste
- Fats / oils / grease municipal lines
- Septic-tank transfer
- Tall-building sewage lifting (DGWQ)
