The Ingco SWP3701 is a 3-inch screw-type submersible well pump designed for deep water extraction from narrow wells and boreholes. Its screw (helical rotor) pump mechanism makes it particularly effective at lifting water from significant depths – up to 72m maximum head – while maintaining a steady flow rate of up to 25 litres per minute.
The entire pump body is constructed from stainless steel, offering strong resistance to corrosion and ensuring a long service life in submerged environments. The motor uses copper wire windings, which provide better conductivity, lower heat generation, and greater durability compared to aluminium-wound alternatives. The slim 3-inch body profile makes it compatible with narrow boreholes and wells where larger 4-inch pumps cannot fit.
The pump connects to a standard 220V-240V, 50Hz single-phase supply and ships with a 9m submersible cable. A separate control box (sold separately, such as the Ingco DWP3701-SB) is recommended for overload protection.
