Submersible Grundfos SL sewage pumps (1.1-11 kW) are fitted with an S-tube® impeller. The free passage through the pump varies from 50-100 mm depending on size.

SL1.100.150.40.4.51E.C

Non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage. The pump is designed for intermittent and continous operations in submerged installation. The revolutionary S-tube® impeller provides free spherical passage of solids up to 100 mm and is suitable for wastewater with a dry matter content of up to 3 %. A unique stainless-steel clamp assembling system enables quick and easy disassembly of the pump from the motor unit for service and inspection. No special tools are required.
