Product Overview
The Grundfos SL.56H.210.4.50D.100 is intended for permanent submerged installation in municipal wet wells and collection basins requiring high-head wastewater transfer. Certified under CE EN12050-1, this cast iron unit includes ROHS and WEEE approvals for handling raw effluents in civil infrastructure. It is designed for operation in liquids with temperatures between 0°C and 40°C.
Performance is delivered by a 21 kW 4-pole motor operating at 1490 rpm on a 3 x 415 V supply. The pump 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 motor is rated for continuous S1 duty and is cooled by the surrounding liquid during normal submerged operation.
The hydraulic system uses an Open S-tube impeller with a 340.8 mm actual diameter to manage untreated wastewater containing solids. The nominal duty head is 23.26 m. Featuring a DN 200 inlet and a DN 100 outlet, this hydraulic design supports high-volume wastewater transfer while reducing the risk of clogging in high-pressure networks.
Built with an EN-GJL-250 cast iron pump housing and motor casing, the pump features a double mechanical shaft seal arrangement and integrated 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. The unit is compatible with the Grundfos auto-coupling system (96090994).
