Ronix Submersible Sewage Pump 2HP, 3-Inch Outlet, 36m³/h Max Flow, Automatic Float Switch RH-4041

The Ronix RH-4041 is a high-performance, industrial-grade submersible sewage pump engineered to handle the toughest wastewater and slurry applications. Driven by a powerful 2HP (1500W) copper-wound motor, it delivers a massive flow rate of 36m³/h and a maximum head of 13.5m. This pump is specifically designed for residential, commercial, and industrial settings where large volumes of waste and solids (up to 25mm in diameter) must be moved efficiently. The rugged cast iron pump housing and stainless steel (S/S 304) motor housing ensure maximum resistance to corrosion and physical wear in underwater environments.

Equipped with an automatic float switch, the RH-4041 provides intelligent water level monitoring, starting and stopping the pump automatically to prevent dry running. It features high-tier safety components, including an IP68 protection rating, a thermal protector to prevent overheating, and a premium SiC–SiC/Ceramic–Graphite mechanical seal for leak-free operation. With its S1 duty cycle rating for continuous operation and a high-efficiency cast iron impeller, the Ronix RH-4041 is the definitive solution for sewage removal, river water lifting, and large-scale drainage tasks.
