Submersible Sewage Pump For Commercial And Industrial Wastewater Treatment 1890 L/S Maximum Flow
S4.135.600.5000.8.78E.H.779.G.N.D.51D
This pump is designed for both intermittent and continuous operation. The cooling jacket ensures that the pump can be installed either submersibly or dry-mounted without motor cooling. The four-channel impeller is capable of handling solids with a size of 135 millimeters. The SmartTrim impeller clearance adjustment system enables the pump to maintain optimal performance throughout its lifespan. For ease of transportation and on-site installation, the pump is equipped with a sturdy lifting bracket. For installation on an automatic coupling system, the Grundfos SmartSeal gasket system provides a leak-proof connection. The pipeline is connected via DIN flanges.
