Waste Water Submersible Pumps
A wastewater submersible pump is lowered into a sump or manhole and moves dirty water containing solids and fibres without clogging, thanks to its free-flow (vortex) impeller.
It is used in basement sewage sumps, septic tanks, car park drainage and industrial wastewater pits. The product range includes 0.34–5 HP models in 220 V and 380 V.
Main Applications
- Basement sewage sumps
- Septic tanks
- Car park and ramp drainage
- Industrial wastewater pits
- Treatment plant lift stations
- Stormwater collection sumps
