Product Overview
Municipal networks requiring significant discharge momentum rely on the SE.56H.280.4.50D.150 for consistent performance in permanent submerged or dry-pit stations. This cast iron unit is intended for municipal and industrial wastewater applications where raw sewage containing solids must be moved reliably. It maintains operation in environments with liquid temperatures ranging from 0°C to +40°C.
The unit achieves a maximum flow rate of 9180 L/min and a maximum head of 46 m using a 28 kW 4-pole motor. Operating on a three-phase 415 V supply with 60.5 Amps, the pump uses an internal cooling jacket for thermal safety. This integrated system ensures that temperature control remains stable during high-capacity transfer in municipal collection systems.
Hydraulic output is driven by an Open S-tube impeller with a 363.2 mm diameter and a 41 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 26.85 m. With a 200 mm inlet and a 150 mm outlet, the configuration supports high-volume transfer while helping to reduce clogging in wastewater infrastructure discharge networks.
Structural durability is provided by an EN-GJL-250 cast iron pump housing and motor casing, featuring a double mechanical shaft seal system. Integrated PTO sensors, moisture switches, and leakage sensors monitor internal motor health to prevent failure in centralized sumps. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and is rated IP68 for 30 metres depth.
