The free passage through the pump varies from 35-125 mm depending on the size and impeller variant. Non-self-priming, single-stage submersible pump for pumping wastewater, service water and untreated raw sewage. The pump is suitable for both intermittent and continuous operation. With cooling jacket, so that in addition to wet installation, dry installation is also possible without additional motor cooling. With S-tube® impeller with a free ball passage of 110 mm. For wastewater with a dry matter content of up to 3 %. With SmartTrim system for impeller gap adjustment to maintain maximum performance over the life of the pump. With Grundfos SmartSeal sealing system for a leak-free connection to a coupling foot bend.
