100 hp Submersible Pump

QJ/QJR Submersible Borehole Pump (Deep Well Pump) designed for pumping clean water from deep wells, rivers, reservoirs and mines etc., as well as applications in industrial water supply , agricultural irrigation projects. Fire fighting and so on.
QJR is specially designed for geothermal applications featured by heat-resisting, anti-corrosion and anti-aging properties, water temperature up to 90℃

Construction & Features

Compact vertical centrifugal multi-stage design with perfect standardization and generalization, easy operation and convenient maintenance.
A complete electric Submersible Pump includes a water pump set, electric motor, a discharge piping, water-proof cable and a Control Panel.
Submersible motor filled with clean water for cooling and lubrication. And the pressure regulation switch, located at the bottom of motor, shall automatically operate to
balance the pressure fluctuation caused by temperature variations.
A sand slinger and oil-sealed skeleton are equipped at the upper part of motor to form a closed operating system for the motor, thus preventing any sand to penetrate into the motor.
Water injection hole, as well as air release hole, are designed at the upper part of the motor, and water release hole at bottom (lower) part.
Thrust bearing and collar are designed at lower part of motor to stand the weight of the squirrel caged rotor and the axial thrust residual.
Water-proof electromagnetic wiring for stator with excellent insulation. 

Zhengzhou Shenlong Pump Industry CO.,Ltd have been exported to more than 70 countries and regions, such as Southeast Asia, Europe, Africa, South America and Oceania and so on. It is the leader in the submersible pump industry in domestic, always stressing on quality and credibility. The company has participated in national standards and plays an important role in amending the national standards, such as CE, ABS.

The main part material of cast iron submersible pump as below:

Water submersible pump features:

1. Good performance, safety and reliable operation

2. Nice appearance, highly energy-saving

3. Low noise, little vibration, simple construction

Steps for water submersible pump:

1.Motor cavity MUST BE fill with clean water when pump working

2.DO NOT use the cable as sling when install, should wear ropes on the handle

3.The first stage impeller should go down the water level

4.After shut down the power, should wait for more than 3mins when restart the pump When the pump finish work, it's better to cut off the power.

We have a instruction video If you don't know clearly. Contact, please.
