The range of Grundfos SE drainage, effluent and sewage pumps is built for years of trouble-free operation. The SE range can operate submerged or dry-installed without motor cooling, and is extremely reliable and very easy to service. The pumps 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.
The pumps are available with SuperVortex impellers (SEV) 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 (SE1) for applications with required high operating hours, dry matter content up to 3 %, and a spherical free passage up to 100 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.
Applications
The SE range of pumps handles wastewater, process water and unscreened raw sewage in heavy-duty municipal, utility and industrial applications and is ideal for large flows.
A number of material variants are available for SE pumps, from variants with a stainless steel impeller to stainless steel variants for aggressive environments, meeting the standards EN 1.4408 and EN 1.4517/1.4539.
