Grundfos has now released its S-tube impeller to the American market following a launch at the recent WEFTEC 2012 exhibition.
Grundfos said its channel impeller, the S-tube, offers greater hydraulic efficiency than its peers without compromising free passage. The impeller has been designed to meet the challenges of handling wastewater, including difficulties with sealing, vibrations, abrasive wear and clogging.
Its design eliminates edges, dead zones and cutting functions that wear over time, relying instead on a patented labyrinth and sealing system that will provide years of trouble-free operation. The impeller's tube shape has been designed to eliminate the need for "advanced and costly add-on assemblies that are designed to cut, shred or treat the wastewater as it flows from the pump".
Meanwhile, a new balancing method results in less vibration and noise, said the manufacturer. Smooth, quiet operation is indicative of greater reliability and a longer lifespan for bearings, shaft seals and other components. The S-tube's hydraulic design ensures less abrasive wear, enhances anti-clogging capabilities and reduces costs over time. www.grundfos.us
