➤Product Advantage
Air Driven Double Diaphragm Pump possesses unique advantages that set it apart from other pumps, including high versatility, safety, and portability.
In various industries, such as electronics, petrochemicals, environmental protection, and food, the pneumatic diaphragm pump holds a leading position in its application.
Here are the distinct advantages of the pneumatic double diaphragm pump:
- [Explosion-proof] - The pneumatic-driven design generates no electric sparks, making it safe to use in flammable and explosive environments.
- [Acid and Alkali Resistance, Solvent Resistance] - The diaphragm design isolates the transported fluid from the driving pneumatic chamber, allowing it to handle dangerous liquid solvents containing strong acids, strong alkalis, corrosive, and volatile substances without posing harm to the environment or users.
- [High Safety] - Operating at pressures ranging from 1 to 8.3 Bar, the pneumatic-driven circulation principle allows for extended dry-running periods without concerns of overheating. Additionally, in case of pipeline blockage and resulting load, the pump stops due to pneumatic balance, preventing the risk of continuous pressure buildup, pipeline rupture, or liquid leakage.
- [Capability to Transport Fluids with Particles] - Thanks to its diaphragm siphon design, the pneumatic double diaphragm pump is highly suitable for transporting fluid containing particles. As long as the particle size remains within the allowable limits of various pump specifications, it ensures smooth fluid transportation without the risk of blockages.
- [Low Shear Force]- The diaphragm siphon design offers the characteristic of low shear force during transportation, ensuring the integrity of fluid particles and preventing their destruction during conveyance. It is particularly suitable for transporting "shear-sensitive substances," such as jam, tapioca pearls, condiments, shampoo, wine, coconut, and more.
- [Efficient Transportation of Viscous Fluids]- Leveraging pneumatic-driven and siphon principles, concerns related to motor torque or the possibility of viscous fluid dry-running are eliminated. The pneumatic diaphragm pump excels in managing fluids with varying viscosities, including resin, slurry, paint, and coatings, ensuring seamless and efficient operations.
- [Compact Size, Lightweight, and Portability]- Powered by compressed air, the pneumatic diaphragm pump operates simply by connecting to an air supply line, eliminating the need for heavy motor systems. This grants significant advantages and convenience in terms of size, weight, mobility, and operation.
The pneumatic diaphragm pump adopts our latest self-developed patented air valve design, allowing it to operate with a minimum air pressure of only 1.0Bar. It possesses numerous advantages, including high efficiency, extended lifespan, and low maintenance costs. Moreover, its inherent design principles eliminate the need for complex control systems, making it highly versatile and applicable across various industries, such as automation, wastewater treatment, mining, shipbuilding, electroplating, chemical, electronics, construction, petrochemical, food, pharmaceuticals, and more. It's safe to say that the pneumatic diaphragm pump is one of the most widely used pumps in the world! Should you have any inquiries or requirements, please feel free to contact us. Thank you!
