The 80WQ40-22-5.5kW submersible sewage pump is designed for wastewater drainage, sewage transfer and site dewatering. Its rated operating point is 40 m³/h at 22 m head, powered by a 5.5 kW submersible motor.
Because the pump and motor operate directly in the liquid, the unit requires no conventional suction priming and can be installed in sewage pits, collection tanks, drainage sumps and wastewater facilities.

In standard WQ model naming, “80" commonly represents the nominal discharge diameter in millimetres. The exact outlet dimensions and flange standard should be confirmed before ordering.
At its rated operating point, the pump delivers approximately:
Actual flow depends on the total system head. Vertical lifting height, pipeline length, pipe diameter, bends, valves and the required outlet pressure must all be included when selecting the pump.
The 22 m head is not the same as the installation depth. A pump installed only a few metres below the liquid level may still require substantial head when discharging through a long or elevated pipeline.
The pump is designed for wastewater rather than clean-water well extraction. Before purchasing, confirm:
A standard sewage pump should not automatically be used for strongly corrosive, highly abrasive, flammable or explosive liquids.
The pump should remain sufficiently submerged during operation. It may be installed as a portable unit with a flexible hose or as a fixed system with guide rails and an automatic coupling, depending on the available configuration.
The discharge pipe should be correctly sized for 40 m³/h. An undersized or excessively long pipe increases friction loss and may prevent the pump from reaching the required flow.
Use a correctly rated control panel with:
For accurate model confirmation, please provide:
No. It delivers 40 m³/h at the rated head of 22 m. Actual flow changes according to the system resistance and pump performance curve.
It is designed for sewage and wastewater, but the permitted solid size depends on the actual impeller and flow-passage design. This specification must be confirmed before ordering.
No. Dry running may cause overheating and seal damage. Low-liquid-level protection is recommended.
Yes. A float switch, level sensor or control panel can start and stop the pump according to the liquid level.
Continuous operation is possible only when the motor duty, cooling conditions, liquid level and application meet the manufacturer’s operating requirements.
