Product Overview
Effluent processing in municipal grid systems is the primary role of the SE.56H.320.4.50D.150, which provides consistent transfer in centralized collection stations. This cast iron model is intended for municipal and industrial wastewater applications, specifically managing raw sewage containing solids. It maintains operational safety in utility networks where liquid temperatures range from 0°C to +40°C.
The pump achieves a maximum head of 45 m and a maximum flow of 9180 L/min when powered by a 32 kW 4-pole motor. Drawing 65.5 Amps on a 415 V supply, the unit utilizes an internal cooling jacket for temperature management. This setup ensures that hydraulic output remains stable during prolonged pumping cycles in high-head collection sumps.
Fluid movement is managed by an Open S-tube impeller with a 371.2 mm diameter and a 44 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 27.64 m. Featuring a 200 mm inlet and a 150 mm outlet with DIN flanges, this configuration supports high-volume transfer while helping to reduce clogging in wastewater infrastructure.
Structural durability is provided by an EN-GJL-250 cast iron pump housing and motor casing protected by double SiC/SiC mechanical shaft seals. Safety is monitored 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 for depths up to 30 metres.
