Product Overview
Industrial wastewater stations and municipal lift projects rely on the high-volume capacity of the SE.56M.320.4.50D.200 for submerged or dry-pit applications. This cast iron model is intended for municipal and industrial wastewater applications, specifically managing raw sewage containing solids. It maintains operational safety in infrastructure environments with liquid temperatures ranging from 0°C to +40°C.
The unit achieves a maximum flow rate of 15720 L/min and a maximum head of 32 m using a 32 kW 4-pole motor. Drawing 65.5 Amps on a 415 V supply, the pump utilizes an internal cooling jacket for thermal safety. This integrated cooling allows for reliable operation during high-capacity transfer cycles in wastewater infrastructure.
Hydraulic handling is characterized by an Open S-tube impeller with a 334.5 mm diameter and a 71 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 17.17 m. Equipped with dual 200 mm inlet and outlet connections, the design supports high-volume transfer while reducing clogging risks in municipal collection systems.
Structural durability is provided by an EN-GJL-250 cast iron motor casing and pump housing protected by double SiC/SiC mechanical shaft seals. Protection is provided by integrated PTO sensors, moisture switches, and leakage sensors for comprehensive motor health monitoring. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure suitable for depths up to 30 metres.

How much water flow and vertical lift can I get from this pump?
You get up to 15720 L/Min in flow and a maximum head of 56M from the Grundfos SE.56M.320.4.50D.200, depending on operating conditions.
What peak dynamic elevation does this pump develop?
To overcome vertical elevation resistance, the SE.56M.320.4.50D.200 develops a maximum pumping head of approximately 56M.
What electrical voltage and motor kilowatt output drive this unit?
Electrical power for the SE-56M-320-4-50D-200 requires a 415 V three-phase connection, driving an efficient 32 kW motor that draws 65.5 Amps.
What is the maximum spherical solids clearance for this pump?
Internal hydraulic clearances in the SE 56M 320 4 50D 200 allow spherical waste up to 71 mm to move through the chamber without lodging.
How high can this pump push fluid through discharge risers?
Dynamic lift generated by the SE/56M/320/4/50D/200 reaches a maximum elevation head of approximately 56M across discharge lines.
