Large-scale collection sumps requiring significant volume handling rely on the SE.56L.215.6.50D.300 for consistent discharge in permanent submerged or dry-pit applications. This cast iron model is intended for municipal and industrial wastewater applications where raw sewage contains solids. It provides reliable hydraulic performance in utility infrastructure where liquid temperatures range from 0°C to +40°C.
The unit achieves a maximum flow rate of 22440 L/min and a maximum head of 16 m using a 21.5 kW 6-pole motor. Operating on a three-phase 415 V supply with 51 Amps, the pump uses an internal cooling jacket for temperature control. This setup facilitates stable thermal management for high-capacity pumping in municipal wastewater infrastructure.
Fluid movement is managed by an Open S-tube impeller with a 390.9 mm diameter and a 105 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 9.02 m. This configuration features dual 300 mm inlet and outlet DIN flange connections, supporting high-volume transfer while reducing clogging risks in municipal collection systems.
Structural durability is provided by the EN-GJL-250 cast iron motor casing and pump housing with double SiC/SiC shaft seals. Motor safety is monitored by integrated PTO sensors, moisture switches, and leakage sensors for operational reliability. The unit includes a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure for depths up to 30 metres.
