Product Overview
Designed for industrial wastewater transfer in demanding environments, the Grundfos SL.56H.210.4.50D.150 is intended for permanent submerged installation. This cast iron unit holds CE EN12050-1 certification and is suitable for treatment facilities and industrial sumps. It is developed for handling untreated wastewater containing solids at temperatures up to 40°C.
The pump features a 21 kW 4-pole motor operating at 1490 rpm on a 3 x 415 V supply. It achieves a maximum flow up to 7860 L/min and a maximum head up to 40 m with a rated current of 52.5 Amps. The system is rated for continuous S1 duty, with thermal management provided by the surrounding liquid during operation.
The hydraulic system uses an Open S-tube impeller with a 340.8 mm actual diameter to handle solids-laden untreated wastewater. The nominal duty head is 23.26 m. The hydraulic design incorporates a DN 200 inlet and a DN 150 (6") outlet, supporting high-volume wastewater transfer while reducing the risk of clogging in industrial collection systems.
Construction features an EN-GJL-250 cast iron pump housing and motor casing with double mechanical shaft seals. Protection is provided by integrated PTO sensors for motor protection and monitoring. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure suitable for installation depths up to 30 metres.
