The Grundfos SL pumps are designed to optimize the operation of a system.

Reliability, simple service, and complete system compatibility are
some of the main advantages.

Grundfos SL pumps are designed for submerged use in network pumping stations,
wastewater treatment plants, public buildings, blocks of flats, and industry.

The Grundfos SLV and Grundfos SL1 pumps are designed to handle unscreened sewage,
effluent, large volumes of surface water and process water in municipal, utility
and industrial applications.

The pumps are available with SuperVortex impellers (Grundfos SLV)
or high efficient channel impellers (Grundfos SL1), allowing for free passage
of solids up to 100 mm in size.

The Grundfos SLV and Grundfos SL1 pumps are designed for permanent submerged
installation, e.g. by means of an auto coupling or a guide rail system,
or for free-standing installation on a ring stand with a flexible pipe connection.
