Product Overview

PRODUCT OVERVIEW
The GNWQ series submersible cutter sewage pump is engineered to handle the toughest wastewater — sewage loaded with rags, fibre, plastic, gloves and stringy solids that clog ordinary pumps. A hardened cutting impeller shreds these solids before they reach the volute, ensuring continuous, clog-free operation and long service life. Fully submersible for quiet, space-saving installation directly in the sump or pit.

KEY FEATURES

  • Hardened cutting/chopper impeller shreds fibre, plastic, rags and gloves — prevents clogging
  • Fully submersible design; quiet operation, no pump house required
  • Double silicon-carbide mechanical seals for reliable underwater sealing
  • Class-F/H insulation motor with thermal overload and dry-run protection
  • Cast iron, SS304 or SS316 construction for standard or corrosive service
  • Wide range from small building-drainage units to large municipal pumps
