            QBY type pneumatic diaphragm pump can not only pump flowing liquid, but also transport some difficult-to-flow media. It has many advantages of self-priming pumps, submersible pumps, canned pumps, mud pumps and impurity pumps.
          1. The QBY type pneumatic diaphragm pump does not need to be filled with water. The suction range is up to 5m. The head reaches 50m. The outlet pressure is ≥5bar.
          2. QBY type pneumatic diaphragm pump has spacious flow and good passing performance. Allow large particles up to 10mm in diameter. The pumping mud and impurities will cause little wear on the pump;
          3. The head and flow can be adjusted steplessly through the valve opening (air pressure adjustment is between 1-7 bar):
          4. QBY-type pneumatic diaphragm pump has no rotating parts and no shaft seal. The medium pumped by QBY-type pneumatic diaphragm pump is completely separated from the moving parts and workpiece medium of the pump, and the conveyed medium will not leak out. Therefore, when pumping toxic, easy-to-use or corrosive media, it will not cause environmental pollution and endanger personal safety;
          5. QBY type pneumatic diaphragm pump does not need electricity. It is safe and reliable to use in flammable and explosive places;
          6. QBY type pneumatic diaphragm pump can be immersed in the medium to work;
          7. QBY type pneumatic diaphragm pump is easy to use, reliable in work, and it only needs to open and close the gas valve when it starts and stops. Even if the pump runs without medium for a long time or suddenly stops due to unexpected circumstances, the pump will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance, when the load returns to normal, it can automatically start operation;
          8. Simple structure and few wearing parts. The pump has simple structure and is easy to install and maintain. The medium conveyed by the pump will not come into contact with the moving parts such as the valve, linkage, etc., unlike other types of pumps due to rotors, pistons, and gears. , Blades and other parts wear and tear and gradually reduce the performance:
          9. It can transport relatively viscous liquids (viscosity below 10,000 centipoise);
          10. The QBY type pneumatic diaphragm pump does not need to be lubricated with oil, even if it is idling. It also has no effect on the pump, which is the characteristic of the pump.
