SEV and SE1 Sewage Pumps

The Grundfos SEV and SE1 heavy-duty submersible sewage pumps from 1.1kW to 11kW are designed for handling wastewater, process water and unscreened raw sewage in heavy-duty municipal, utility and industrial applications.

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

The SEV and SE1 pumps can be used in permanent dry or submerged installations by means of an autocoupling system or with a fixed pipe connection. They do not need separate motor cooling arrangements. The pumps are also suitable for freestanding installations or as portable pumps.

Unique benefits of the SEV and SE1 pumps

• Non-stop operation thanks to unique liquidless motor cooling enabling round-the-clock operation in dry and wet installations without motor modifications
• Moisture-proof cable entry – the plug is filled with a two-component compound that prevents moisture entering the motor via the cable core
• Cartridge shaft seal – the primary and secondary mechanical shaft seals are combined into a compact easy-to-replace cartridge unit
• Maximum flexibility thanks to the quick-detachable and interchangeable motor units which fit both channel-impeller and SuperVortex pumps
