Product Overview

The WQK Series Cutter Submersible Sewage Pump is a submersible sewage pump equipped with a cutting mechanism that macerates solids, fibres and debris before they enter the pump impeller. This cutting action prevents clogging and enables reliable sewage transfer even when the wastewater contains rags, plastics and other fibrous materials that would otherwise cause blockages in conventional sewage pumps.

This pump is widely used in commercial basement drainage, municipal wastewater systems and institutional sewage management. Depending on regional terminology, it may also be referred to as a Cutter Submersible Pump, Macerator Submersible Sewage Pump, Cutter Submersible Sewage Pump or WQKCutter Sewage Pump.

Final model selection should be confirmed according to the actual duty point, sewage composition and project conditions.

Installation and Maintenance

Installation Guidance

The submersible pump should be installed in a sump or wet well with adequate clearance for removal during maintenance. An auto-coupling system should be used for straightforward pump installation and removal. The discharge piping must be properly connected and supported.

Pre-Start Inspection

Before starting the pump, confirm the following:

• Pump is properly positioned in the sump or wet well
• Auto-coupling connection is secure and properly aligned
• Discharge piping connection is complete and leak-free
• Electrical cable is properly connected and insulated
• Cutting mechanism rotates freely without obstruction
• Float switch or level sensor is correctly set for automatic operation

Routine Maintenance

Regular inspection should include:

• Checking cutting mechanism for wear and damage
• Monitoring motor insulation resistance
• Verifying that the pump maintains the required flow and head during test runs
• Inspecting auto-coupling and guide rail system
• Checking float switch or level sensor operation
