The Grundfos SE 1.1-11 kW Submersible Pump is built for years of trouble-free operation. This Pump can operate submerged or dry-installed without motor cooling, and is extremely reliable and very easy to service. The Grundfos SE 1.1-11 kW can be permanently installed using an auto-coupling guide-rail system or a fixed pipe connection; it is also suitable for freestanding installation or for use as portable utility pumps.
The SE 1.1-11 kW is 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.
