QJD stainless steel submersible well pump features
Our QJD stainless steel submersible well pumps for sale come in a wide range of sizes. We have 3 inch submersible well pump developed on the basis of 75QJ deep well submersible water pump, 4 inch submersible well pump developed on the basis of 100QJ, 5 inch submersible well pump developed on the basis of 125QJ and 6 inch submersible well pump on the basis of 150QJ.

QJD stainless steel submersible well pump raw materials
The main parts of them are made of stainless steel and copper alloy, rather than cast iron. Therefore, you will find QJD series look shiny, feel smoother, and work more reliably and with higher efficiency. What’s more, we have cast stainless steel and stamping and welding stainless steel, 304# stainless steel, 316# stainless steel and 316l# stainless steel for your choice.
Besides, we have used wear-resistant materials to make its impellers and discharge bowl, so this stainless steel submersible water pump works especially well in pumping water with sands. We have added a pressure balance film to it, so you can submerge it as deep as 120 m under water. We also have made its shaft “float” by way of a special design. In this way, there will be no axial pressure when the stainless steel well pump runs.
Model meaning and specifications of QJD stainless steel submersible well pump
QJD has quite a wide range of models. Let us take model 75QJD2-22-0.75 for instance. Meanings of “Q” and “J” are same as that of QJ series submersible deep well pumps. Besides, the meaning of the four digits in this model is same as that of QJ series submersible deep well water pump too. The additional letter D stands for single phase power supply. Those models here begin with 75QJ are 3 inch pumps, and those begin with 100QJ are 4inch pumps. 125QJ is 5 inch pumps and 150QJ is 6 inch pumps. The following table lists part of the models of QJD series.
Working conditions of QJD stainless steel submersible well pump
QJD’s working conditions are same as that of QJ deep well submersible water pump, except that QJD series are oil-filled submersible pump, not water-filled type. They have oil-filled submersible motor instead of water-filled submersible motor, which helps to save energy. The insulation grade of the oil-filled motor is B and the protective grade of it is IP68. Some models of QJD series shall connect to single phase 220v or 230v power source, while other models shall connect to three-phase 380v power source. But the frequency of the power source all should be 50Hz.
