The Samoa 1½” AODD Pump (DF250, Aluminum-PTFE-PTFE) is a versatile and durable air-operated double diaphragm pump designed for a variety of fluid handling tasks. Here’s a breakdown of its features:

• Application Range: This pump is designed for tasks such as dosing, spraying, transferring, and evacuating fluids. It is suitable for common applications with moderate flow rates, making it ideal for fluid distribution in various industries.
• Material Construction: The pump features an aluminum body, known for being lightweight yet durable. It uses PTFE (Polytetrafluoroethylene) diaphragms, which provide excellent chemical resistance, ensuring the pump performs well even with aggressive fluids.
• Durability: Built for demanding environments, the DF250 is designed to withstand continuous use and challenging conditions, making it a highly durable metal pump.
• ATEX Certification: This model is ATEX-certified for use in potentially explosive environments (Ex II2 GD IIB/IIC 95°C). It is also fully groundable, ensuring safe operation in environments where explosive gases or dust may be present.
• Chemical Compatibility: The DF250 pump is well-suited for a variety of chemicals, including stainless steel- and aluminum-friendly fluids. It can handle paints, inks, and varnishes, especially those that use solvents like ketones, acetates, aldehydes, as well as aliphatic and aromatic hydrocarbons.

This pump is commonly used in industries such as paint and coatings, chemical processing, and printing, where fluid transfer of solvent-based materials and chemicals is necessary. It provides efficient and safe handling of fluids in environments that may involve volatile or explosive materials.
