QBY Air-operated diaphragm pumps

Air-operated diaphragm pumps:
Pneumatic pumps are a type of pump product that does not require a motor and only requires compressed air as a power source. QBY pneumatic pumps can achieve energy-saving and power-saving effects. QBY series pneumatic pumps have a variety of material options, and the diaphragm and other accessories are selected according to the degree of corrosiveness of the medium. It is commonly used in industries such as petroleum, chemical, textile, and papermaking.

A. Main features

1. No need to pour water, the suction distance is up to 7m, the head is up to 50m, and the outlet pressure is ≥6kgf/cm2;
2. It has wide flow and good passing performance, and allows the maximum particle diameter to pass through to reach 10mm. When pumping mud and impurities, there is little wear on the pump;
3. The lift and flow rate of the diaphragm pump can be adjusted steplessly through the opening of the air valve (the air pressure is adjusted between 1-7kgf/cm2);
4. There are no rotating parts and shaft seals. The diaphragm completely separates the pumped medium from the moving parts and working medium of the pump, and the pumped medium will not leak out. Therefore, when pumping toxic, volatile or corrosive media, it will not cause environmental pollution or endanger personal safety;
5. No electricity is required, and it is safe and reliable to use in flammable and explosive places;
6. Can work while immersed in the medium;
7. The pneumatic diaphragm pump is convenient and reliable. It can be started and stopped by simply opening and closing the gas valve. Even if it runs without medium for a long time or stops suddenly due to unexpected circumstances, the pump will not be damaged. Once overloaded, the pump will automatically stop and has self-protection performance. When the load returns to normal, it will automatically start running;
8. Simple structure and few wearing parts. The pneumatic diaphragm pump has a simple structure and is easy to install and maintain. The medium transported by the pump will not contact the air distribution valve, connecting rod and other moving parts. Unlike other types of pumps, the performance will gradually decline due to the wear of the rotor, piston, gear, blade and other parts.
9. It can transport relatively viscous liquids (viscosity below 10,000 centipoise);
10. No oil lubrication is required, and even if it runs idle, it will not have any effect on the pump. This is a major feature of this diaphragm pump.

B. Main Application

1. Sucking peanut butter, pickles, mashed potatoes, sausages, jam apple paste, chocolate, etc.
2. Absorb paint, gum and pigment.
3. Adhesives and glues, all types can be pumped.
4. Glaze slurry for various tiles, porcelain, bricks and pottery.
5. After the well is drilled, the sediment is pumped out and grouting is done.
6. Pump various emulsions and fillers.
7. Sucking various sewage.
8. Use pumps to clean out the wastewater in tankers and barges.
9. Hops and yeast slurry, syrup, and molasses.
10. Suction of water in mines, pits, tunnels, ore dressing and slag. Pumping of cement grout and mortar.
11. Various rubber pastes.
12. Various abrasives, corrosives, petroleum and mud, cleaning grease and general containers.
13. Various highly toxic, flammable and volatile liquids.
14. Various strong acids, strong alkalis, and highly corrosive liquids.
15. Various high temperature liquids can withstand up to 150℃.
16. Used as the front-stage pressure-feeding device for various solid-liquid separation equipment.
