QS series of water-filled wet submersible pump 1, the working parameters of the flow range: 10-250 m3 / h, head range: 5 -121m, diameter range: φ30 ~ φ150mm, temperature range: ≤30 ℃ 2, Product Overview QS column submersible pumps widely used in agricultural irrigation, sprinkler irrigation wells for water, industrial and civil supply, drainage systems, as well as hills, mountains of water, low-lying areas of drainage, industrial and mining enterprises and rural water supply, drainage and other water conservancy facilities. Its characteristics are motors, pumps, assembled into one, simple structure, easy installation and removal, small footprint, maintenance is simple, safe and reliable operation, do not pollute the water and so on. 3. Conditions of Use Power: frequency 50 Hz, voltage 380 V (tolerance +5% - 10%) of the three-phase AC power. Submerged pump should be safe to run, dive depth of not less than 0.5 meters. Water: general non-corrosive water, sand content of not more than 0.02%, PH value: 6.5 to 8.5 were extracted water temperature no higher than 30 ℃. Before using the motor cavity to be filled with water, non-water running. The main purpose of QS submersible pumps are widely used in agricultural irrigation, industrial and civil construction sites supply, drainage system, fountain project, as well as hills, mountains of water, drainage and other low-lying areas. Its characteristics are: motors, pumps assembled into one, simple structure and easy installation and removal, less installation footprint, use and maintenance is simple, safe and reliable operation.
