Grundfos SE – SL wastewater pumps provide the highest total efficiency on the market. Innovative technologies from Grundfos bring together intelligence, motors, hydraulics and functionality to meet the challenges of modern wastewater, maximising the hydraulic, electrical and mechanical efficiency of your pumps.

The pumps are available with SuperVortex impellers for applications with required low operating hours, dry matter content up to 5 %, and a spherical free passage up to 100 mm, or with the S-tube impeller for applications with required high operating hours, dry matter content up to 3 %, and a spherical free passage up to 160 mm.

The S-tube impeller is the only impeller on the market designed to cope with the challenges of modern wastewater with varying dry matter content. The simple and robust design of the S-tube impeller offers world class hydraulic efficiency without compromising free passage.

Built for years of trouble-free operation, the SE and SL ranges can operate submerged or dry installed without motor cooling. In addition, they are extremely reliable and very easy to service.

Applications
The SE and SL ranges of pumps handle wastewater, process water and unscreened raw sewage in heavy-duty municipal, utility and industrial applications. They can be permanently installed using an auto-coupling guide-rail system or a fixed pipe connection; the pumps are also suitable for freestanding installation or for use as portable utility pumps.
