Product Overview
Civil flood control and groundwater drainage sumps requiring high-capacity discharge utilize the SE.56L.280.6.50D.300 for centralized transfer projects. This cast iron 6-pole pump is intended for municipal and industrial wastewater applications specifically managing untreated effluents containing solids. It maintains consistent performance in infrastructure environments where liquid temperatures range from 0°C to +40°C.
The unit achieves a maximum flow up to 25380 L/min and a maximum head of 20 m using a 28 kW motor. Drawing 59.5 Amps on a three-phase 415 V supply, the pump incorporates an internal cooling jacket for temperature management. This integrated system ensures that thermal stability remains high during high-capacity pumping in wastewater infrastructure.
Central to its hydraulic dynamics is the Open S-tube impeller with a 411.2 mm diameter and a 105 mm free passage for managing untreated wastewater containing solids. The nominal duty head is 10.46 m. Equipped with dual 300 mm inlet and outlet connections, the design supports high-capacity transfer while reducing clogging risks in municipal collection systems.
Structural durability is provided by the EN-GJL-250 cast iron casing and double SiC/SiC mechanical shaft seals. Protection includes integrated PTO sensors, moisture switches, and leakage sensors for comprehensive motor health monitoring. The unit includes a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure for installation depths to 30 metres.
