Submersible Pump

Working conditions: 1. The voltage needs 380V, and its deviation cannot exceed ±5%. The frequency needs 50HZ, and its deviation cannot exceed ±1%, and it need three-phase AC power supply. 2. Inner cavity of motor must full of distilled (water of clean water ) 3. The first stage impeller of water pump should immerge hydrodynamic level above 3m. The electric pump units immerge hydrostatic level above and cannot exceed 70m. The distance between bottom of motor and bottom of well cannot less than 5m. 4. Its temperature should be the max of 20 ℃. 5. The content of solid matter (base mass) should be within 0.01%. 6. Acid-base titration PH value of water is 6.5~8.5 7. The content of hydrogen sulfide should not exceed 1.5mgl in water. 8. The content of cholrine ion should not exceed 400mgl in water.
