Series overview
The WQ submersible non-clog pump is built for energy efficiency and reliability in heavily polluted wastewater. Because the unit runs submerged there is no suction line to prime and no separate pump house.
The same platform is produced as the LW vertical pump, the YW submersible sump pump and the GW pipeline pump, chosen according to the sump geometry and the discharge arrangement on site.
Design features
- Non-clogging hydraulic design with a wide passage through the impeller
- Runs submerged, so no suction pipe or priming is required
- The same platform is offered as LW vertical, YW submersible sump and GW pipeline pumps
- Selected as a replacement for imported units in municipal and industrial duty
