The QDX series submersible pump:
Introduction:
QDX series submersible pump is composed of three parts: pump body, mechanical seal and single-phase asynchronous motor. The pump body is installed at the upside, the centrifugal type of the impeller. The single-phase asynchronous motor is installed at the downside. Double sides between pump and motor are sealed with mechanical seal, which is O-type oil resistant rubber as stationary seal.
Application:
QDX series small submersible pumps adopt downside absorption structure and the mechanical double-layer seal, with the characteristic of compact structure, small volume, convenient usage, which have been widely applied in well pumping, river pumping, irrigation and drainage in breeding industry, garden watering and hotel, canteen, high-rise building etc.
Working Conditions:
The pump can work continually at the following condition:
1.Medium temperature is less than +40°C
2.Medium PH is between 6.5 to 8.5
3.Cubic ratio of impurity solid is less than 0.1%, and the granularity size less than 0.2mm
4.Submersible depth is not deeper than 5m
