The Grundfos SEV and SE1 pumps are designed for handling wastewater, process water and unscreened raw sewage in heavy-duty municipal, utility, and industrial applications.

These two technologically very advanced series of pumps are available with efficient single-channel or SuperVortex impellers allowing for free passage of solids up to 100 mm in size. This greatly reduces the risk of clogging, and ensures maximum up-time and low operating costs.

The SEV and SE1 pumps can be permanently installed by means of an auto-coupling system or with a fixed pipe connection, submerged or dry, without separate motor cooling arrangements. The pumps are also suitable for free-standing installation, or as portable utility pumps.


The SE pumps are designed to optimise the operation of a system. Reliability, simple maintenance, and complete system compatibility are some of the main advantages.
