Product Overview
Flood control facilities and stormwater pumping systems frequently install this slow-speed ductile iron submersible sewage pump for ultra-high-volume submerged operation. Massive flows of untreated effluents and raw sewage with solids are handled efficiently in large-scale drainage infrastructure.
Flow reaches 45000 L/min with a maximum head of 7.2 m, driven by a 35 kW slow-speed motor. The 10-pole motor operates at 585 rpm on a 415 V three-phase supply, drawing 77 Amps for consistent hydraulic performance during peak demand periods.
A ductile iron 3-channel impeller with 120 mm solids passage allows safe passage of large particles without internal clogging. The three-channel design optimizes flow for ultra-high-volume transfer while maintaining operational stability.
Ductile iron housing with IP68 enclosure and Class F insulation provides extreme submerged durability. A dual SiC/SiC shaft sealing system prevents liquid ingress, while moisture sensors offer active motor protection. Includes a 15 m power cable and rated for depths up to 20 m.
FEATURES
- 3-Channel Ductile Iron Impeller: Ultra-high-volume solids handling.
