Pneumatic Diaphragm Pump QBY3-20 Cast iron

QBY3 Pneumatic diaphragm pump performance characteristics

QBY3 Pneumatic diaphragm pump is the third generation of our company, it has the 8 advantages of reasonable structure, reliable performance, longer service life, lower noise, smaller vibration, non-stop, non-crash, better workmanship. It could be used on both flowing liquid and slow flowing medium, has many of the advantages of self suction pump, submersible pump, shield pump, pump mud and impurities and other transportation machinery.

1.No irrigation water, suction up to 5 m, lift up to 70 m, the outlet pressure ≥ 7bar;
2.Can transport more viscous liquid (viscosity 10,000 cps or less-is similar to the viscosity of honey);
3.No need for electricity, safe and reliable to be used under flammable, explosive circumstances;
4.Can be immersed in the medium;
5.No need for oil lubrication, even idle, nor any effect on the pump, which is a major feature of the pump;
6.Flow spacious, good performance, allowing the maximum particle diameter of 10 mm. Pumping mud, when impurities, little wear and tear on the pump;
7.Lift and flow can achieve stepless adjustment (pressure adjustment between the 1-7bar) through the valve opening degree;
8.The pump has no moving parts, no seals, diaphragm pumps and other pumping media with moving parts, completely separated from the workpiece medium, the transmission medium does not leak out.  It will not lead any environmental pollution and danger to personal safety when the pump working with the toxic, volatile or corrosive media.
9.Simple structure, less wearing parts, simple pump structure, installation, easy maintenance, pumping medium does not come into contact with the valve, linkage and other moving parts, unlike other types of pumps due to the rotor, piston, gear wear leaving the performance of the blade and other parts of the gradual decline;
10.Easy to use, reliable, open stop simply open and close the gas valve, even if because of accident-free medium long run or sudden stop pump will not be damaged, once the overload, the pump will automatically shut down with

Safety tips: in order to protect our environment, please when use should pay special attention to in the process of dismantling for environmental impact.
