    Centralized collection stations and industrial drainage networks frequently use this ductile iron submersible sewage pump for permanent submerged installation. Raw sewage and untreated effluents with high concentrations of organic matter and large particulates are handled reliably in demanding wet well environments.

    Hydraulic output reaches 26400 L/min flow and 16.1 m head, powered by a 35 kW motor. The 8-pole motor operates at 732 rpm on a 415 V three-phase supply, drawing 73 Amps for consistent performance across regional collection grids.

    A ductile iron 2-channel impeller with 140 mm solids passage provides exceptional debris handling capability, allowing extremely large particles to pass without internal clogging. This ensures steady flow patterns when transferring heavily contaminated wastewater.

    Cast iron housing with IP68 enclosure and Class F insulation provides extreme submerged durability. A dual SiC/SiC mechanical shaft seal prevents liquid ingress, while moisture sensors offer active motor protection. Includes a 15 m H07RN-F power cable and rated for depths up to 20 m.

    FEATURES

    • 2-Channel Ductile Iron Impeller: Optimized for solids handling in high-volume transfer.
    • 140 mm Solids Passage: Exceptional clearance for very large contaminants.
    • IP68 Submersible Enclosure: Sealed for permanent operation at depths up to 20 metres.
    • Dual SiC-SiC Mechanical Shaft Seals: Protects against liquid ingress.
    • Built-in Moisture Monitoring: Early detection prevents motor failure.
    • Industrial-Grade Cast Iron Housing: Resists wear and corrosion.
    • 35 kW Motor: Continuous duty rating with Class F insulation.
    • Star/Delta Starting: Controlled power draw and reduced mechanical strain.
