Product Description

Air Operated Diaphragm Pump Product Overview:

AODD series Air Operated Diaphragm Pump produced by KEMAI of China is a new type of conveying machinery, using compressed air as the power source to transport various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, toxic liquids. The performance parameters are similar to those of the WLLDENPVMPS from The Federal Republic of Germany and the MARlOWPUMPS from the United States. AODD Air Operated Diaphragm Pump can pump both flowing liquid and some viscous and emulsion substances which are not easy to flow.

AODD 20/25 Air Operated Double Diaphragm Pump advantages：

Air Operated Diaphragm Pump can not only pump flowing liquid, but also transport some not flowing media, with self-primed pumps, submersible pumps, shielded pumps, mud pumps and impurities pumps and other transport machinery many advantages.

1. No irrigation water is needed. Suction up to 5m. The head reaches 70m. Outlet pressure ≥6bar.
2. Spacious flow with good passing performance. Maximum particle diameter allowed through up to 10mm. When pumping mud, impurities, little wear on the pump;
3. Head and flow can be adjusted stepless through the opening of air valve (air pressure is adjusted between 1 and 7 bar) :

4. the pump no rotating parts, no shaft seal, diaphragm pump | and other pumping media and moving parts of the pump, the workpiece media is completely separated, the medium will not leak             out. So when pumping toxic, easy to play or corrosive media, will not cause environmental pollution and harm to personal safety;

5. No electricity. Safe and reliable use in inflammable and explosive places;
6. Can work immersed in medium:

7. easy to use, reliable work, start and stop simply open and close the gas valve. Even if due to unexpected circumstances and a long time without medium operation or sudden stop pump will not         be damaged. In case of overload, the pump will shut down automatically with self-protection. When the load returns to normal, it can start to run automatically.

8. simple structure, less wear parts, the pump structure is simple, easy to install and maintain, the pump medium will not contact the valve, link and other moving parts, unlike other types of                 pumps due to the wear of rotor, piston, gear, blade and other parts of the performance of the gradual decline:

9. It can transport relatively viscous liquid (viscosity below 10,000 cp) :

10. the pump does not need oil lubrication, even idling. It also has no effect on the pump, which is the biggest characteristic of the pump.
