Grundfos Offers SE and SL Pumps with the S-tube Technology. The S-tube is the only impeller available in the wastewater market that does not compromise hydraulic efficiency or free passage through the pump.

The S-tube impeller and the new tube design through the pump provide:

• World-class hydraulic efficiency up to 84% without compromising free passages
• Spherical free passage up to 160mm, meaning better solids handling and greater non-clogging capabilities.

• A design as simple and robust as a tube results in longer lifetime and lower maintenance costs.
