["【53 FT Lift Sewage Pump】Equipped with a 1.5 HP PSC motor, the sewage grinder sump pump ensures powerful performance. The septic tank pump achieves up to 4,300 gallons per hour (GPH) or vertically lifts water to 53 feet. Even at a 20-foot drop, the sewage pump can reach 3,050 gallons per hour, making it ideal for environments requiring significant elevation changes. It is the perfect choice for basements, sump pits, industrial sites, and septic tank applications.","【Heavy Duty & Clog-Resistant Design】Built with a rugged cast iron casing, designed for residential sewage and effluent wastewater transfer from sewage basins to sewage systems or tanks. Non-clog vortex impeller handles up to 3/4\"solid, suitable for basement water pumps, septic tanks, sewage wells, sewage treatment systems.","【Automatic Operation】The adjustable float switch automatically starts and stops the sewage sump pump based on the water level. When the water level exceeds 14.17 inches, the pump automatically starts; when the water level drops to 4.72 feet, the pump automatically stops. The float switch has undergone 300,000 cycle tests to ensure long-term use. The pump is equipped with a 10-foot power cord, providing you with ample space for operation. Warning: Do not pull the power cord to lift the sewage pump, as this may cause damage. Note: The length of the float switch may be adjusted according to your specific requirements.","【Overheat Protection, Ensuring Safety】Energy-efficient oil-immersed copper motors maintain heat dissipation. The thermal overload protection function prevents motor burnout during dry running or voltage fluctuations, ensuring low-temperature motor operation to extend service life. The cast iron sewage/effluent pump is also fitted with an air release valve to prevent air locks and ensure smooth water flow. Note: In low-temperature environments, fully submerge the pump and insulate it to ensure optimal performance.","[CUSTOMER FIRST] 100% manufacturer test, 3-year worry-free manufacturer after service.
