WQK Series Submersible Grinder Sewage Pump with Cutting Blade

Non-Clog Chopper Pump for Municipal & Industrial Wastewater

📌 Product Overview

The WQK Series Submersible Grinder Sewage Pump​ is engineered for reliable handling of domestic, commercial, and industrial wastewater containing long fibers, rags, paper, plastics, and small solid particles.

Equipped with a high-hardness alloy cutting blade and stationary grinding ring, the pump shreds fibrous materials into fine particles before discharge—effectively preventing clogging in pipes and valves.

It is widely used as a cost-effective alternative to conventional non-clog sewage pumps where waste contains sanitary tissue, hair, or textile fibers that would block standard impellers.

Key Features

• Built-in Grinding / Cutting System​ Hardened alloy cutter + fixed grinding ring continuously chops solids and fibers to pass freely through the discharge line.
• Anti-Clog Hydraulic Design​ Single-channel or vortex impeller (model dependent) minimizes risk of blockage; maintains high flow even with suspended solids.
• Durable Construction​
  • Pump casing Casing:​ Heavy-duty Cast Iron (FC200 / HT250)​
  • Impeller:​ Cast Iron​ standard, 304 Stainless Steel (AISI 304)​ optional
  • Shaft:​ 304 SS or 2Cr13 stainless steel
  • Fasteners:​ Stainless steel
• Double Mechanical Seal with Oil Chamber​ Tungsten carbide / Silicon carbide (TC/TC or SiC/SiC) in oil bath — extends seal life and allows safe dry-run monitoring.
• Motor Protection & Options​
  • Class F insulation, IP68 protection
  • Built-in thermal overload protector (optional)
  • Auto float switch for liquid-level control (optional)
  • Control panel with leakage / overload protection (optional)
• Easy Installation​ Fully submersible, auto-coupled guide rail system available; suitable for wet pit / sump installation.

🏢 Typical Applications

• Hotels, Hospitals & Restaurants​ — Kitchen and sanitary wastewater with tissues/fibers
• Underground Parking Lots & Basement Drainage​ — Sewage lifting where gravity flow is unavailable
• Municipal Sewage Treatment Plants​ — Pre-grinding before primary treatment
• Residential Communities & Commercial Buildings​ — Sewage pumping stations
• Industrial Wastewater​ — Factories discharging wastewater with textile fibers, paper pulp, or plastic scraps
