Description

Performance Overview
QBY air-operated diaphragm pump delivery flow of liquid, but also convey some uneasy flowed medium, with advantages of the self-priming pump, submersible pumps, shielding pumps, mud pumps and other transportation machineries.
1. No need of water irrigation , suction lift up to 7m, head up to *0m, the outlet pressure ≧ 6kgf/cm2;
2. High flow-ability, good performance, with allowance of the maximum particle diameter of *0mm, minimal wear and tear on the pump while conveying mud, and impurity;
3.Head, flow step-less adjustment can be achieved through the valve opening degree (pressure adjustment between the **7kgf/cm2);
4.Without moving parts and seals, diaphragm will completely separate transport medium and pump running parts, working medium, the transmission medium does not leak out. So it will not cause environmental pollution and danger to personal safety when transporting of toxic and flammable or corrosive media;
5. No electricity, safe and reliable use in explosive areas;
6. No immersed in media while operation;
7. Easy operation, reliable duty, start and stop simply by opening and closing the gas valve, even due to accident or suddenly stop running without media for a long time, pump will not be damaged, once overload, the pump will automatically shut down, through self-protection function, when the load is back to normal, and it can automatically start running;
8.Simple structure, less wearing parts, easy installation and maintenance, medium conveyed by the diaphragm does not come into contact with valves, connecting rods and other moving parts, it will not impact performance by wearings of the rotor, pistons, gears, and other parts of the impeller like other types of pumps;
9.It can transport more viscous medium (viscosity *0,**0 cps or less);
*0. No need of lubrication oil, no impact if running without load;
 
The main purpose
1.Pumping peanut butter, pickles, mashed potatoes, sausage, chocolate, hops, syrup, etc.;
2.Pumping paints, lacquers, glues, adhesives, etc;
3.Pumping all kinds of tile, porcelain, tiles and pottery, etc;
4.Pumping all kinds of abrasive, corrosive, cleaning grease, etc.;
5.Pumping all kinds of toxic, flammable and flammable liquids,etc; 
6.Pumping various of sewage cement grout and mortar, etc.;
7.Pumping a variety of acids, alkalies, corrosive liquids,etc.;
8.As pre-delivery pressure device of a variety of solid-liquid separation equipments;
