Grundfos SL – Wastewater Pumps

Grundfos SL Range – Grundfos SL1 – Grundfos SLV

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.
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 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 (SLV) or high efficient channel impellers (SL1), allowing for free passage of solids up to 100 mm in size.
The SLV and 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.
