Submersible Sewage Pump WQ Range LEO

Submersible Sewage Pump WQ Range LEO

The LEO WQ Submersible Sewage Pump Range is built for demanding wastewater and drainage applications where a standard clean-water pump simply isn't suitable.

Designed for sewage, wastewater and drainage, these heavy-duty submersible pumps are suitable for applications ranging from factories and construction sites to municipal sewage systems, residential drainage stations and agricultural water management.

Depending on the selected model, the WQ range can handle suspended particles from 20mm up to 80mm, making it suitable for moving wastewater containing solids and debris within the pump's specified limits.

With an IP68 motor enclosure, copper winding and maximum immersion depth of 5 metres, the WQ range is designed for dependable submerged operation in demanding drainage environments.

Built for Demanding Wastewater Applications

Unlike a standard drainage or clean-water pump, the LEO WQ range is designed specifically for wastewater applications where suspended solids may be present.

Depending on the selected model, these pumps can accommodate particles between 20mm and 80mm, while the fully submersible IP68 design allows the pump to operate directly within the wastewater being transferred.

The range of different motor powers and configurations makes it easier to select a WQ pump for anything from commercial drainage to larger industrial and municipal wastewater systems.

Choosing the Correct WQ Pump

When selecting a sewage pump, consider more than motor power alone. The required flow rate, head height, particle size, voltage, connection type and installation conditions should all be matched to your system.

For larger WQ models, make sure the required control equipment and electrical installation are correctly specified for the selected pump.

The LEO WQ Submersible Sewage Pump Range provides a heavy-duty solution for moving wastewater in commercial, industrial, agricultural and municipal drainage applications.
