The pumps with water-filled motor are designed for the well of colliery, which with good heat dissipation, long service time and low cost. At the same time, it can drain water completely.
It has the advantage of simple structure, easy to installation and removal, small volume, safe and reliable operation without polluting the water and so on.
1, 50 Hz(tolerance±2%, ), 380 V voltage (tolerance±10%, ) of the three-phase AC power.
2, The water temperature is less than 30degree celsius.
3, The distance between pump and the bottom of well is not less than 3m
4, The water PH value is 6.5 ~ 8.5.
5, The sand content of water is less than 0.02%, 6, The motor must be full of water before work!
