Untreated effluents and raw sewage containing large solids are handled reliably in permanent submerged installations.\u003c\/p\u003e\u003cp\u003eFlow capacity reaches 50400 L\/min with a maximum head of 8.4 m, powered by a 50 kW slow-speed motor. The 8-pole motor operates at 726 rpm on a 415 V three-phase supply, drawing 98 Amps for consistent torque delivery during peak collection periods.\u003c\/p\u003e\u003cp\u003eA ductile iron 3-channel impeller with 120 mm solids passage prevents internal clogging by allowing large particles and organic contaminants to pass safely. The three-channel design optimizes flow for ultra-high-volume transfer while maintaining operational stability.\u003c\/p\u003e\u003cp\u003eDuctile cast iron construction with IP68 enclosure and Class F insulation ensures maximum submerged durability. SiC\/SiC shaft seals and integrated moisture sensors protect against liquid ingress. Includes a 15 m power cable and rated for depths up to 20 m.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e3-Channel Ductile Iron Impeller: Ultra-high-volume displacement with reliable solids handling.\u003c\/li\u003e\n\u003cli\u003e120 mm Solids Passage: Extra-wide clearance for untreated sewage and large contaminants.\u003c\/li\u003e\n\u003cli\u003eIP68 Enclosure: Fully sealed for permanent submerged operation.\u003c\/li\u003e\n\u003cli\u003eDuctile Cast Iron Construction: Enhanced structural strength and wear resistance.\u003c\/li\u003e\n\u003cli\u003eSiC\/SiC Mechanical Shaft Seals: Durable barrier against moisture ingress.\u003c\/li\u003e\n\u003cli\u003eActive Moisture Sensing: Real-time monitoring with early warning protection.\u003c\/li\u003e\n\u003cli\u003e50 kW Slow-Speed Motor: 8-pole design with high torque at 726 rpm.\u003c\/li\u003e\n\u003cli\u003eStar\/Delta Starting: Reduces stress and power surges during startup.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
