The Samoa ½” AODD Pump (DF50, Aluminum-PTFE-Stainless Steel) is a highly durable and versatile air-operated double diaphragm pump designed for low to moderate flow rate applications. Its robust construction and chemical compatibility make it suitable for demanding industrial uses involving viscous fluids and solvent-based materials.

Key Features:

  1. Material Construction:

    • Pump Body: Aluminum, offering excellent durability and corrosion resistance in compatible environments.
    • Diaphragms: PTFE (Polytetrafluoroethylene), ensuring resistance to aggressive chemicals and extended service life.
    • Balls: Stainless steel, enhancing the pump’s capability to handle higher-viscosity fluids effectively.
  2. Applications:

    • Designed for:
      • Dosing
      • Spraying
      • Transferring
      • Evacuating
      • Spreading fluids
    • Suitable for handling:
      • Paints, inks, and varnishes made with solvents (e.g., ketones, acetates, aldehydes, aliphatic, and aromatic hydrocarbons).
      • Fluids with higher viscosities, thanks to the stainless steel balls.
  3. Chemical Compatibility:

    • Compatible with chemicals that do not corrode aluminum or stainless steel.
    • Not suitable for chlorinated hydrocarbon solvents.
  4. Performance and Efficiency:

    • Ideal for applications requiring low to moderate flow rates, providing consistent and reliable fluid transfer.
  5. Safety Features:

    • Fully ATEX-certified (Ex II2 GD IIB/IIC 95 °C) for safe operation in potentially explosive environments.
    • Groundable design for added safety in hazardous settings.
  6. Durability:

    • Constructed to withstand demanding applications, offering long-lasting performance.

Advantages:

  • Versatile Fluid Handling: Capable of transferring various solvent-based fluids and viscous materials.
  • Robust Design: Aluminum body and stainless steel components ensure durability in harsh industrial environments.
  • Safety Certified: ATEX-certified and groundable for use in explosive or hazardous areas.
  • Efficient Operation: Handles low to moderate flow rates with ease, maintaining consistent performance.
  • Specialized Viscosity Handling: Stainless steel balls enhance performance with thicker fluids.

The Samoa ½” AODD Pump (DF50, Aluminum-PTFE-Stainless Steel) is an excellent choice for industries such as coatings, printing, and chemical processing, where handling solvent-based materials and higher-viscosity fluids is critical. Its combination of durable materials, safety certification, and reliable performance ensures it meets the demands of rigorous industrial applications.
