Diagnostics of Grundfos S Submersible Pumps, Sizes 70 and 72

We carried out diagnostic work on Grundfos S submersible pumps in sizes 70 and 72.

Grundfos S pumps are used in many wastewater systems. Their robust, wear-resistant design includes SmartTrim impeller-clearance adjustment and the SmartSeal leakage-prevention system.

The SmartTrim system used in S pumps makes it easier to adjust the factory-set impeller clearance and maintain pump efficiency.

The SmartSeal automatic coupling seal provides a tight connection between the pump and coupling base. The mechanical seal can rotate in either direction. Where pumps have separate pipework, regular backflushing can help prevent sludge deposits.
