QDX is a submersible pump. What does "X" mean?
It should be small.There is no "downdraft" term;Do not say submersible pumps do not suck, what kind of pump is not on suction, or left and right suction

QDX is a submersible pump model, its specific meaning is:1.Q: submersible pump.2.D: single-phase power supply, three-phase electricity is not marked.3.X: pump, pump type is not marked.Complete submersible pump model will generally add rated flow, rated lift and motor power rating. For example: QDX40-8-1.5, meaning with single-phase 1.5KW motor, rated flow of 40 cubic meters / time, the rated lift of 8 meters under the pump submersible pump.According to the different relative position of pump and motor, submersible pump is divided into pump type and pump type. The pump submersible pump motor in the above, below, this structure greatly reduces the radial size of the pump, so much for submersible pump and small submersible pump operation. Submersible pump submersible pump on top of the pump in the following, it is divided into two types of internal and external type. The submersible pump carries the liquid through the annular flow passage around the motor, then cools the motor and then flows out of the pump outlet. Even though the pump is near the drain sump, there is no need to worry about the temperature rise of the motor, so the application is becoming wider and wider. External pump submersible pump directly from the pressurized water chamber after the impeller or diffuser outlet of discharged liquid, motor is cooled by liquid pumping. As the lower pump structure can work in a relatively shallow liquid, it is often used in submersible pumps for operating surfaces, especially the main structure of large caliber submersible pumps.
