S-tube impeller

Overview

Overview

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 key to the design is simplicity, with no cutting or moving functions that can get worn over time and hereby ensuring a constant, superior efficiency over time. The S-tube impeller is a tube-shaped impeller placed in a pump housing that matches the smooth tube shape through the entire pump with no obstructions or dead zones through the hydraulic.

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

  • World-class hydraulic efficiency up to 84% without compromising free passage.
  • 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.

The difficulties in designing high-efficiency impellers have traditionally been challenges with sealing against backflow, vibrations, abrasive wear and clogging. The Grundfos S-tube impeller meets and surpasses all these challenges.

Furthermore, we have tested the S-tube in the field in many hundreds of wastewater installations worldwide prior to release with very good results. What our customers experienced was substantially lower noise and vibration levels, reduced maintenance, and far better non-clogging capabilities than ever experienced previously.
