【HIGH QUALITY MATERIAL】- The submersible well pump is made of 304 stainless steel, rust- and saltwater resistant, and thus highly durable and waterproof for a long time to use. It is convenient and efficient to use water. 【ESSENTIAL PARAMETER】- Submersible Pump Voltage: 110V 50HZ, Flow Rate: max. 42 GPM; Delivery Height: max. 630 ft(192 m); The Length of Cable: 32.8 ft(10 m); Power: 3HP(2250W). The copper motor and steel rotor provide excellent performance. 【HIGHER PUMP HEAD & FLOW】- Powerful flow of water well pump can achieve 42GPM, and the maximum head lift can reach 630 ft. Heavy-duty thermoplastic impellers design provides high flow up and high head, excellent performance, and a long lifespan. 【EXCELLENT PERFORMANCE】- The submersible pump is designed with a built-in check valve, and it can be mounted vertically and suitable for home-usage. The hermetically sealed motor is thermally protected to prevent overheating and uses less energy. 【WIDELY USED】- This deep well pump is suitable for extraction from the deep wells for groundwater and uses in rivers, reservoirs, canals, and other water lifting works. They are mainly used in farmland irrigation and mountainous areas, and for draining in cities, factories, railways, and mines.
