Brief introduction:
The NQB pneumatic diaphragm pump can not only pump flowing liquids, but also transport some non flowing media, and has many advantages over conveying machinery such as self-priming pumps, submersible pumps, shielded pumps, mud pumps, and impurity pumps.  

Performance and features:

NBQ pneumatic diaphragm pump can not only pump flowing liquids, but also transport some media that are not easy to flow. It has many advantages over conveying machinery such as self-priming pumps, submersible pumps, shielded pumps, mud pumps, and impurity pumps.
1. No need for water injection, with a suction height of up to 7m, a lift of 70m, and an outlet pressure of ≥ kgf/cm2;
2. Spacious flow and good performance, allowing for a maximum particle diameter of 10mm. When pumping mud and impurities, there is minimal wear on the pump;
3. The head and flow rate can be infinitely adjusted through the opening of the air valve (the air pressure can be adjusted between 1-7kgf/cm2);
4. NBQ pneumatic diaphragm pump has no rotating parts and no shaft seal. The diaphragm completely separates the pumped medium from the moving parts and workpiece medium of the pump, and the conveyed medium will not leak outward. So when pumping toxic, easily reactive or corrosive media, it will not cause environmental pollution and endanger personal safety;
5. No need for electricity, safe and reliable use in flammable and explosive gases;
6. Can work submerged in a medium;
7. Easy to use, reliable in operation, with simple opening and closing of the gas valve for on/off operation. Even if the pump runs without medium for a long time or suddenly stops due to unexpected situations, it will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance. When the load returns to normal, it can start and operate automatically;
8. The NBQ pneumatic diaphragm pump has a simple structure and few vulnerable parts. The pump has a simple structure, easy installation and maintenance, and the medium transported by the pump does not come into contact with the operating components such as the distribution valve and connecting rod. Unlike other types of pumps, the performance gradually decreases due to wear and tear of the rotor, piston, gear, blades, and other components;
9. Can transport viscous liquids (viscosity below 10000 centipoise);
10. The NBQ pneumatic diaphragm pump does not require oil lubrication and has no impact on the pump even when idling, which is a major feature of the pump.

Main applications of NQB pneumatic diaphragm pump

1. Peanut butter, kimchi, mashed potatoes, sausage, chocolate, hops, syrup, etc;
2. Paint, pigments, adhesives, binders, etc;
3. Various types of tiles, porcelain, bricks, and ceramic glazes, etc;
4. Various abrasives, corrosives, cleaning oil stains, etc;
5. Various highly toxic, flammable, and easily playable liquids, etc;
6. Various types of sewage, cement grouting, and mortar, etc;
7. Various strong acids, strong alkalis, strong corrosive liquids, etc;
8. As a front-end pressure feeding device for various solid-liquid separation equipment.
