S Pumps
S pumps are the most important part of many sewage systems. In addition to its strength and durability, it is also preferred because of its innovative features such as the impeller clearance adjustment system SmartTrim and the leakage prevention function Smart Seal.
The SmartTrim system on S pumps allows the factory-set impeller clearance to be readjusted to your needs, thus maintaining maximum pump efficiency.
A leak-proof connection is achieved between the pump and the base unit of the auto-coupling system using the Grundfos SmartSeal auto-coupling seal. The packing can rotate in both directions. If pumps are installed with a separate piping system, sludge build-up can be prevented by backwashing at regular intervals.
