Product Overview
Designed for municipal pump stations, the Grundfos SL.56H.410.4.50D.150 is intended for permanent submerged installation in centralized collection sumps. This cast iron pump is certified under CE EN12050-1 and includes ROHS and WEEE approvals for handling untreated wastewater. It is engineered for consistent service in civil infrastructure handling liquids at temperatures between 0°C and 40°C.
The unit features a 41 kW 4-pole motor running at 1485 rpm on a 3 x 415 V supply with a rated current of 78 Amps. It achieves a maximum flow up to 12180 L/min and a maximum head up to 50 m. For continuous S1 duty cycles, the motor utilizes the surrounding pumped liquid for thermal cooling during operation.
The hydraulic system uses an Open S-tube impeller with a 392.4 mm actual diameter to handle untreated wastewater containing solids. The nominal duty head is 30.4 m. It incorporates a DN 200 inlet and a DN 150 outlet, supporting high-volume wastewater transfer while reducing the risk of clogging in civil utility networks.
Constructed with an EN-GJL-250 cast iron pump housing and motor casing, the pump features double mechanical shaft seals and PTO sensors for motor protection and monitoring. It includes 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 (97695489).
