Product Detail

[4"Single phase submersible electric pumps]
Outer casing of pump is made of stainless steel, the whole body is made by blocking production, high precision structure, insulation and machine noise all reach the characteristics of the high-quality product of the same kinds in the world, also accord with the Euro-American high-quality standard.
The impeller and diffuser adopt macromolecule wear-resistance materials, and made by pressing and molding, it is high wear-resistance, with long life, and also cannot oxidize, rust or pollute. Unique floating impeller structures, no axile-centred force to the motor, capable of completing multilevel high flow.
The multiple check valve is incorporated inside the discharge head which can effectively prevent the impact of precipitating water and sediment of the reflux sands when the motor stops, ensure startup of pump fluently, also can prolong motor life effectively.
The motor uses high quality thrusting bearing, has high seal, and also has pneumatic balance anti-press device, to ensure operating more stably, high efficiently and use for longer time.
Stainless steel casing, alloy rubber bearing, sand-proof and high wear-resistance.
Integrated electric water level control ensure water-pumping automatically.
Multi-stepped protection by electric control box enables the motor run safely and reliably.
Small outside diameter, high capacity, high head, suitable for small-caliber well and can reduce the boring cost obviously.
Advanced low noise design making pump operates quietly.
