Product Overview
Effluent processing sumps in municipal grid systems utilize the SE.56M.280.4.50D.200 for high-capacity transfer and reliable submerged service. This cast iron model is intended for municipal and industrial wastewater applications where raw sewage contains solids. It is engineered to maintain performance in utility networks with liquid temperatures ranging from 0°C to +40°C.
The pump achieves a maximum flow of 14880 L/min and a maximum head of 30 m while powered by a 28 kW 4-pole motor. Operating on a 415 V supply with 60.5 Amps, the unit incorporates an internal cooling jacket for temperature control. This setup facilitates stable thermal management for high-capacity pumping in wastewater infrastructure.
Central to its hydraulic performance is the Open S-tube impeller with a 326 mm diameter and a 71 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 15.77 m. Featuring dual 200 mm inlet and outlet connections with DIN flanges, this hydraulic configuration supports high-volume transfer while helping to reduce the risk of clogging in municipal collection systems.
Structural integrity is maintained by the EN-GJL-250 cast iron casing and double SiC/SiC mechanical shaft seals. Safety is monitored by integrated PTO sensors, moisture switches, and leakage sensors for proactive 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 to 30 metres.

What peak dynamic elevation does this pump develop?
Fluid elevation through vertical risers reaches up to 56M with the Grundfos SE.56M.280.4.50D.200 under standard duty points.
What peak flow capacity and vertical elevation does this pump produce?
You get up to 14880 L/Min in flow and a maximum head of 56M from the SE.56M.280.4.50D.200, depending on operating conditions.
What maximum vertical elevation head can this pump achieve?
To overcome vertical elevation resistance, the SE-56M-280-4-50D-200 develops a maximum pumping head of approximately 30 m.
Does this pump run on standard household power or three-phase power?
Electrical power for the SE 56M 280 4 50D 200 requires a 415 V three-phase connection, driving an efficient 28 kW motor that draws 60.5 Amps.
What size spherical waste can pass through the pump chamber?
Internal hydraulic clearances in the SE/56M/280/4/50D/200 allow spherical waste up to 71 mm to move through the chamber without lodging.
