Electric Diaphragm Pump
We are a professional manufacturer of Electric Diaphragm Pumps, offering high-quality and stable performance. Our pumps have been widely used in various industries, providing reliable solutions for water pumping and material transfer.
1. **Brief Description**
The QBY air-operated double diaphragm pump is an ideal choice for handling both liquid and difficult-to-pump materials. It combines the advantages of self-priming pumps, submersible pumps, shielded pumps, slurry pumps, and impurity pumps.
- No need to prime the pump; it can suction up to 7 meters in height.
- The delivery head can reach up to 70 meters, with pressures exceeding 6 kgf/cm².
- It features a wide flow range and excellent performance, allowing particles up to 10 mm in diameter to pass through with minimal damage to the pump.
- The flow and pressure can be adjusted steplessly via a pneumatic valve, with pneumatic pressure ranging from 1 to 7 kgf/cm².
2. **Key Features**
- No rotating parts or bearing seals, ensuring complete separation between the pumped medium and the internal components. This prevents leaks and reduces environmental pollution and safety risks when handling toxic, flammable, or corrosive substances.
- No electricity required, making it safe for use in flammable and explosive environments.
- Easy to operate—just open or close the air valve to start or stop the pump. Even during long periods without material flow, the pump remains undamaged.
- Simple structure with fewer wearing parts, making installation and maintenance convenient.
- Can handle viscous liquids (viscosity below 10,000 centipoise) without oil lubrication, even when idling.
3. **Main Applications**
- Suitable for pumping peanut butter, pickles, tomato puree, sausages, chocolate, syrup, paint pigments, adhesives, ceramic slurries, grinding materials, corrosive agents, solvents, cement, mortar, acids, alkalis, and more.
- Can also serve as a front-stage transmission device for solid-liquid separation equipment.
