S Pump

S pumps form the backbone in many sewage systems. They get chosen for their strength, their durability, and for innovative features such as the SmartTrim impeller clearance adjustment system, Smart Seal for leakage prevention and robustness.

The SmartTrim system of the S-pumps makes it easy to adjust the factory-set impeller clearance and thus maintain maximum pump efficiency.

The Grundfos SmartSeal Auto-coupling gasket provides a complete leak-proof connection between the pump and the base unit of the auto-coupling system. The shaft seal is capable of rotating in either direction. When pumps are installed with separate pipe work, sludge sedimentation can be avoided by back flushing the system at regular intervals.

Applications

The pumps are suitable for the following applications:

• Transfer of unscreened raw sewage
• Transfer of raw water
• Pumping of water containing sludge
• Pumping of industrial effluent
