QJ Submersible Water Pump

QJ series wells use submersible pumps are used to dive into water. It is used for farmland irrigation, urban and rural tap water, water supply of industrial and mining enterprises, ground source heating, refrigeration and other working places. Compared with the universal pump, it has the advantages of no noise, no pollution, small floor area, less investment, energy saving, environmental protection, convenient maintenance, low cost and easy realization of automatic control.

Conditions of use

1: no impurity water, frozen water / cooling water, rainwater, coal mine, iron ore, metal mine and other underground water gushing, reference water, mineral water and so on.

2: allow working water temperature range from +5 to +25 C

3: the content of solid impurities (mass ratio) is not more than 0.01%

4: pH (PH) 6.5-8.5

5: the content of hydrogen sulfide is not more than 1.5mg/L

6: the content of chlorine ion is not more than 400mg/L

7: the unit must completely invade the water to work.


Structural advantage

1: high single stage lift, single stage pump shell height, shorten the whole machine height makes the operation of the product is very stable.

2: the casting uses the HT200 super deep well pump shell and the increase of the pressure coefficient depends on the spheroidal graphite cast iron or the cast steel.

3: the design of the check valve is unique. The adoption of the design avoids the malfunction of the valve body and the lifting of the unit due to the strong impact force of the backwater hammer when the pump is stopped.

4: the diameter of the pump shaft is far larger than the national standard diameter, which increases the safety factor of the extraction of the underground water source of the super deep well.

5: the design of small axial force or no axial force makes the service life of the motor greatly increased, and the working efficiency of the whole unit is improved relatively.
