Product Overview
The Grundfos SL.56M.240.4.50D.200 is designed for permanent submerged installation in municipal wastewater handling and lift station applications. This cast iron unit holds CE EN12050-1 certification and is engineered for handling untreated wastewater containing solids. It is suitable for use in civil collection systems with liquid temperatures up to 40°C.
The pump incorporates a 24 kW 4-pole motor running at 1490 rpm on a 3 x 415 V supply with a rated current of 56 Amps. It achieves a maximum head up to 26.5 m and a maximum flow up to 13980 L/min. This model is rated for continuous S1 duty and uses the surrounding liquid for thermal management during operation.
The hydraulic design uses an Open S-tube impeller with a 316.5 mm actual diameter. The nominal duty head is 14.28 m. The system features DN 200 inlet and outlet connections following DIN flange standards, supporting high-volume wastewater transfer while reducing the risk of clogging in municipal networks.
Built with an EN-GJL-250 cast iron pump housing and motor casing, the pump features double mechanical shaft seals and integrated PTO sensors for motor protection and monitoring. It is supplied with a 10-metre S1BC4N8-F EMC power cable and features an IP68 enclosure suitable for installation depths up to 30 metres.
