Submersible Sewage/Waste Water Pump – Cast Iron Excellence, Black Elegance, Premium Drainage Solutions
Product Overview
GaoTian’s submersible sewage pump is a robust, cast iron-based centrifugal pump designed for demanding drainage environments. Featuring a sleek black epoxy-coated finish and a corrosion-resistant cast iron body (HT250), it delivers unmatched durability, wear resistance, and mechanical stability. Certified under ISO9001 quality management and CE safety standards, it efficiently handles high-solid content wastewater in municipal sewage systems, industrial effluent treatment, agricultural irrigation, construction dewatering, and residential septic tank cleaning.
Core Specifications & Performance Advantages
Material & Craftsmanship
Body Construction: Durable gray cast iron (HT250) with compressive strength ≥250MPa, surface-treated with epoxy resin for acid/alkali resistance and anti-corrosion performance.
Impeller Design: 304 stainless steel impeller with cutting blades to pulverize solids (up to 50mm) like fibers, plastics, and hair, preventing clogs.
Sealing System: Dual-layer protection (mechanical seal + graphite packing) ensures zero leakage with a service life of ≥8,000 hours.
Power & Efficiency
Motor Options: 220V/380V three-phase motors (5.5–30kW) support flow rates of 10–300 m³/h and heads up to 50m.
Energy Savings: Equipped with high-efficiency rare-earth motors (IE5 rating), reducing energy consumption by 15–20% compared to traditional models.
Intelligent Features
Auto-Protection: Built-in sensors detect overloading, phase loss, overheating, and dry running, triggering automatic shutdowns to prolong lifespan.
Remote Monitoring: Optional 4G/Wi-Fi modules enable real-time tracking of water level, flow rate, and energy usage via mobile apps or cloud platforms.
Applications & Customized Solutions
Municipal Drainage: Ideal for sewage plants, river dredging, and emergency flood control in urban areas.
Industrial Wastewater: Handles corrosive liquids (pH 2–3) and high suspended solids (SS ≤50g/L) in chemical and food processing industries.
Agricultural Irrigation: Efficiently drains fields and prevents soil compaction, with eco-friendly black design blending into natural landscapes.
Construction Sites: Rugged construction for foundation dewatering and mud pumping in harsh conditions.
Residential Use: Silent operation (≤70dB) for basement flooding prevention and septic tank maintenance.
Technical Differentiators
Modular Design
Split pump-motor flange connection allows quick access for impeller replacement or seal maintenance (takes ≤10 minutes).
Optional stainless steel filter basket (20mm mesh) to trap large debris.
Environmental Adaptability
Operating temperature range: -20°C to 80°C, suitable for cold climates and tropical regions.
IP68 rating for continuous submersion at 1m depth; EX II 2G explosion-proof version available.
