1. **Brief Description**
The QBY air-operated double diaphragm pump is an ideal choice for handling both liquid and difficult-to-pump media. It combines the advantages of self-priming pumps, submersible pumps, shield pumps, slurry pumps, and impurity pumps.
- No need to prime the pump; it can achieve a suction lift of up to 7 meters.
- The delivery head can reach up to 70 meters with pressure exceeding 6 kgf/cm².
- It has a wide flow range and good performance, allowing particles up to 10 mm in diameter to pass through without damaging the pump.
- The flow and pressure can be adjusted steplessly via the pneumatic valve, with a pressure range of 1–7 kgf/cm².
- It has no rotating parts or mechanical seals, ensuring complete separation between the medium and the pump components. This makes it safe for conveying toxic, flammable, or corrosive substances.
- No electricity is required, making it suitable for use in hazardous environments.
- It is easy to operate, reliable, and only requires opening or closing the gas valve when starting or stopping. Even if operated without liquid or paused for long periods, the pump remains undamaged.
- It features a simple structure, fewer wearing parts, and low maintenance. The conveyed medium does not come into contact with the pneumatic valve or coupling lever.
- It can handle viscous liquids (viscosity below 10,000 cP) and does not require lubrication, even during idling.
2. **Main Applications**
This pump is suitable for a wide range of applications, including:
- Transporting food products like peanut butter, pickles, tomato puree, sausages, chocolate, and syrups.
- Conveying paints, pigments, adhesives, and glues.
- Handling glazed slurries from ceramics, porcelain, bricks, and china.
- Moving grinding materials, corrosive agents, and cleaning oil residues.
- Pumping toxic, flammable, or volatile liquids.
- Transferring slurry, cement, and mortar.
- Conveying strong acids, alkalis, and other corrosive liquids.
- Serving as a front-end transmission device for solid-liquid separation equipment.
