Continuous submerged operation in centralized collection systems is where this unit performs best, delivering reliable transfer of heavily contaminated wastewater.\u003c\/p\u003e\u003cp\u003eA 65 kW motor drives the hydraulic system, achieving a maximum head of 64 m and a flow capacity of 12900 L\/min. The 4-pole motor operates at 1476 rpm on a 415 V three-phase supply, drawing 124 Amps. This configuration maintains consistent hydraulic performance during peak demand periods in regional collection grids.\u003c\/p\u003e\u003cp\u003eSolids handling is managed by a ductile iron 1-channel impeller with an 80 mm passage, allowing large particles to pass without blocking. This ensures steady flow when transferring untreated wastewater and minimizes downtime caused by debris in raw sewage applications.\u003c\/p\u003e\u003cp\u003eIP68 enclosure and Class F insulation protect the cast iron housing during permanent submerged installation. A dual mechanical SiC\/SiC shaft sealing system prevents liquid ingress, while integrated moisture sensors provide active motor protection. The unit includes a 15 m H07RN-F power cable and supports Star\/Delta starting, with a maximum installation depth of 20 m.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1-Channel Ductile Iron Impeller: Handles solids efficiently in municipal wastewater transfer.\u003c\/li\u003e\n\u003cli\u003e80 mm Solids Passage: Allows large contaminants to pass without blocking.\u003c\/li\u003e\n\u003cli\u003eIP68 Submersible Enclosure: Rated for permanent operation at depths up to 20 metres.\u003c\/li\u003e\n\u003cli\u003eDual SiC-SiC Mechanical Shaft Seals: Protects against liquid ingress.\u003c\/li\u003e\n\u003cli\u003eIntegrated Moisture Sensors: Detects moisture ingress to prevent motor failure.\u003c\/li\u003e\n\u003cli\u003eIndustrial-Grade Cast Iron Housing: Resists wear and corrosion in aggressive applications.\u003c\/li\u003e\n\u003cli\u003e65 kW Motor: Continuous duty rating with Class F insulation.\u003c\/li\u003e\n\u003cli\u003eStar\/Delta Starting: Reduces mechanical stress during startup.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
