Selection Guidance

To select the appropriate WQ Series submersible sewage pump, please provide the following information:

• Required flow rate (m³/h)
• Required head (m)
• Sewage composition (solid particle size, fibre content)
• Sump or wet well dimensions
• Available voltage and frequency
• Submergence depth
• Operating conditions and duty cycle

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
• Impeller rotates freely without obstruction
• Float switch or level sensor is correctly set for automatic operation

Routine Maintenance

Regular inspection should include:

• Checking mechanical seals for leakage
• 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

Available Configurations
