Grundfos SE V pumps

Capacity up to 88 l/s - The award winning SE range are heavy duty submersible pumps designed to handle wastewater, process water and raw sewage in heavy duty applications.

The Grundfos SE range of pumps is built for years of trouble-free operation. The SE range can operate submerged or dry-installed without motor cooling. 

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 pumps are suitable for the following applications:

  • Wastewater
  • Process water
  • Unscreened raw sewage

Unique design

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.
