Product Overview
Designed for permanent submerged installation, the Grundfos SL.56H.240.4.50D.100 is engineered for high-head sewage pumping applications in municipal infrastructure. This cast iron submersible pump holds CE EN12050-1 certification with ROHS and WEEE environmental approvals. It is suitable for lift stations and collection systems handling raw effluents and untreated wastewater.
A 24 kW 4-pole motor powers the unit at 1490 rpm on a 3 x 415 V supply with a rated current of 56 Amps. The pump achieves a maximum head up to 43 m and a maximum flow up to 9600 L/min. This model is rated for continuous S1 submerged service in liquids between 0°C and 40°C, using the surrounding media for motor cooling.
The hydraulic system uses an Open S-tube impeller with a 351 mm actual diameter to manage untreated wastewater containing solids. The nominal duty head is 24.9 m. The hydraulic design features a DN 200 inlet and a DN 100 outlet, supporting high-volume wastewater transfer while reducing the risk of clogging in municipal discharge systems.
Construction features an EN-GJL-250 cast iron pump housing and motor casing with 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. The pump is compatible with the Grundfos auto-coupling system (96090994).
