QBK cast iron pneumatic diaphragm pump

Introduction to QBK Cast Iron Pneumatic Diaphragm Pump:

The QBK pneumatic diaphragm pump produced by Haitan Pump Industry is the third generation pneumatic diaphragm pump, which has the advantages of long service life and no stoppage. It uses compressed air as the power source and can pump and absorb various corrosive liquids, granular liquids, high viscosity, volatile, and flammable liquids. It has been formed into a standardized production and the product quality is highly praised. The main feature of this pump is that it does not require water injection. It can pump flowing liquids and transport some easily flowing media. It has a high suction stroke and adjustable head (0-70 meters). The gas source pressure only needs to be greater than 1kg/cm2 to work. It is fireproof and explosion-proof, and has all the functions of submersible pumps, self-priming pumps, impurity pumps, shielded pumps, mud pumps, and many characteristics of conveying machinery

Application of QBK cast iron pneumatic diaphragm pump:

1. Pump peanut butter, kimchi, mashed potatoes, sausage, chocolate, hops, syrup, etc.
2. Pump paint, gum, pigment, adhesive, and glue, etc.
3. Pump and suck various tiles, porcelain, bricks, and ceramic glaze slurry.
4. Pump various abrasives, corrosives, and clean oil stains.
5. Pump various flammable and volatile liquids.
6. Pump various types of sewage, cement grouting, and mortar.
7. Pump various strong acids, strong alkalis, strong corrosive liquids, etc.
8. Use a pump to clean the oil tanker and a barge to extract sewage from the warehouse.
9. Various high-temperature liquids can withstand up to 150 ℃.
10. As a front-end pressure feeding device for various solid-liquid separation equipment.

Performance:

1. No need for irrigation and water diversion. The suction lift can reach up to 5m, the head can reach 50m, and the outlet pressure is ≥ 6kgf/c ㎡;
2. Spacious flow and good performance. It allows for the passage of the largest particles with a diameter of up to 10mm. When pumping mud and impurities, there is minimal wear on the pump;
3. The head and flow can be infinitely adjusted through the opening of the air valve (the air pressure can be adjusted between 1-7 bar):
4. Yingluo Ke pneumatic diaphragm pump has no rotating parts, no shaft seal, and the medium pumped by the diaphragm is separated from the moving parts and workpiece medium of the pump, so 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. Not using electricity. It is safe and reliable to use in flammable and explosive places;
6. Can work submerged in a medium:
7. Easy to use, reliable in operation, and only requires simple opening and closing of the gas valve. 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 automatically start and run again;
8. Pneumatic diaphragm pump has a simple structure and few vulnerable parts. This pump has a simple structure and is easy to install and maintain. The medium transported by the pump does not come into contact with moving parts such as the valve and connecting rod. Unlike other types of pumps, the performance gradually decreases due to wear and tear of components such as the rotor, piston, gear, and blades
9. Can transport viscous liquids (viscosity below 10000 centipoise):
1. Pneumatic diaphragm pumps do not require oil lubrication, and even when idling, they have no impact on the pump, which is the biggest feature of this pump.
