Product Overview
The Grundfos SL.56M.360.4.50D.200 is designed for permanent submerged installation in municipal raw sewage transfer stations. This cast iron pump holds CE EN12050-1 approval and includes ROHS and WEEE environmental certifications. It is suitable for handling untreated wastewater containing solids in large-scale collection networks requiring reliable discharge performance.
Performance is delivered by a 36 kW 4-pole motor running at 1485 rpm on a 3 x 415 V supply with a rated current of 71 Amps. It achieves a maximum flow up to 16500 L/min and a maximum head up to 35 m. The motor is rated for continuous S1 duty in untreated wastewater at temperatures ranging from 0°C to 40°C.
The hydraulic system uses an Open S-tube impeller with a 342.2 mm actual diameter to handle solids-laden untreated wastewater. The nominal duty head is 18.49 m. It features DN 200 inlet and outlet connections with DIN flange standards, supporting high-volume wastewater transfer while reducing the risk of clogging in raw sewage applications.
Built with an EN-GJL-250 cast iron pump housing and motor casing, the unit includes double mechanical shaft seals and PTO sensors for motor protection and monitoring. It is supplied with a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure suitable for installation depths up to 30 metres.
