This cast iron pump holds CE EN12050-1 approval and includes ROHS and WEEE environmental certifications. It is suitable for handling untreated wastewater containing solids in large-scale collection networks requiring reliable discharge performance.\u003c\/p\u003e\u003cp\u003ePerformance is delivered by a 36 kW 4-pole motor running at 1485 rpm on a 3 x 415 V supply with a rated current of 71 Amps. It achieves a maximum flow up to 16500 L\/min and a maximum head up to 35 m. The motor is rated for continuous S1 duty in untreated wastewater at temperatures ranging from 0°C to 40°C.\u003c\/p\u003e\u003cp\u003eThe hydraulic system uses an Open S-tube impeller with a 342.2 mm actual diameter to handle solids-laden untreated wastewater. The nominal duty head is 18.49 m. It features DN 200 inlet and outlet connections with DIN flange standards, supporting high-volume wastewater transfer while reducing the risk of clogging in raw sewage applications.\u003c\/p\u003e\u003cp\u003eBuilt with an EN-GJL-250 cast iron pump housing and motor casing, the unit includes double mechanical shaft seals and PTO sensors for motor protection and monitoring.
