Well, get ready to have your well up and running again in no time! Our deep well submersible pump provides a large flow and high head lift, meeting all your water needs. Pump it up today with our submersible well pump! Large Flow High Head Premium Quality Reliable Details Vertical Installation Horizontal Installation Well Pumping Farm Irrigation Domestic Water Livestock Water Q: How long is the electrical cable that comes with the pump? A: 33 ft. Q: Does this deep well pump have the wire splice kit included? A: Yes. Q: Does this deep well pump require a foot valve or some type of screen on the bottom? A: This pump has a built-in check valve. However, it is always recommended to install additional check valve(s) on top of the pump and above. Thank you. Q: How many inches of wells does this pump fit? A: Fits a 4-inch well. Features & Details Enhanced Pump Flow & Head: Power: 3HP, 230V; Diameter: 4″ (for 4″ or bigger well casing); Discharge: 1-1/4″ NPT. This deep well submersible pump is designed with 18-stage thermoplastic impellers, providing 37GPM max flow and 640 ft max head. It comes with an external control box and a 33 ft electric cord, making life without modern plumbing a lot easier. Pump out your worries with ease and relax. No challenge is too big for you. Upgraded Stainless Steel: The whole frame of our deep well pump is unlike anything on the market. It is made of stainless steel, including the outlet and connecting components. You don’t have to worry about it becoming rusted or corroded after being underwater for a long time. With ETL certification and IP68 waterproof grade, the pump can be used for 8-10 years. Stop wasting time! The perfect choice is in front of you! Reliable Copper Motor: Are you tired of previous submersible well pumps failing you? Are you ready for consistent satisfaction and quality? The powerful copper motor and high-precision rotor promise long-term stable running. The motor features built-in overload protection, allowing it to automatically stop when stuck or during abnormal situations to prevent burning. NOTICE: DO NOT use it without water or at a low water level to avoid idle running. Trouble-free Check Valve & Filter: This well pump has a built-in check valve to prevent back-flow (an additional check valve is highly recommended). The stainless steel filtration mesh is designed to filter impurities. You can add a layer of gauze in front of the filtration inlet for a new drilled well that may contain excessive granular sediment. Keep impurities out without the headache. Use It Anywhere: Whether you want to solve water supply problems for industry, farmland, or home, this deep water well pump is the one you can trust. It works excellently as a garden water source and sprinkler for the kids. You can use the pump for extracting water from deep wells, reservoirs, canals, rivers, and other water-lifting works. Note: We use the standard US plug for the 230V deep well pump, the same as the 115V plug. However, the 230V is industrial power with many kinds of plugs. You can cut off the plug for installation if the plug does not match. This product and the power cord are tested according to the 230V standard, fully meeting the 230V use environment.
