NO COMPROMISE BETWEEN FREE PASSAGE AND HYDRAULIC EFFICIENCY The S-tube impeller does not compromise free passage or hydraulic efficiency Efficiency: World class hydraulic efficiency without compromising free passage Free passage: Greater free passage means better solids handling and greater non-clogging capabilities Simplicity: A design as simple and robust as a tube results in longer lifetime and lower maintenance costs Wastewater is not what it used to be. In fact, varying solids and water content in wastewater has always been a challenge. The S-tube from Grundfos is the only impeller that meets these challenges. The traditional trade-off between free passage and efficiency when pumping wastewater is no more – now you can concentrate on maximising your up time and reducing your costs.
