Product Overview
Large-scale municipal stormwater networks and flood control systems frequently rely on this slow-speed ductile iron submersible sewage pump for ultra-high-volume transfer. Untreated effluents and raw sewage containing large solids are handled reliably in permanent submerged installations.
Flow 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.
A 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.
Ductile 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.
FEATURES
- 3-Channel Ductile Iron Impeller: Ultra-high-volume displacement with reliable solids handling.
- 120 mm Solids Passage: Extra-wide clearance for untreated sewage and large contaminants.
- IP68 Enclosure: Fully sealed for permanent submerged operation.
- Ductile Cast Iron Construction: Enhanced structural strength and wear resistance.
- SiC/SiC Mechanical Shaft Seals: Durable barrier against moisture ingress.
- Active Moisture Sensing: Real-time monitoring with early warning protection.
- 50 kW Slow-Speed Motor: 8-pole design with high torque at 726 rpm.
- Star/Delta Starting: Reduces stress and power surges during startup.
