The Samoa 1" AODD Pump (DF200, Conductive PVDF-PTFE-PTFE) is a high-performance air-operated double diaphragm pump designed for demanding fluid handling tasks. Here are the key features:

• Application Range: Like other AODD pumps, this model is suitable for dosing, spraying, transferring, evacuating, and dispensing a wide variety of fluids. It is designed for high-flow applications where both performance and efficiency are critical.
• Material Construction: The pump is made from conductive PVDF (Polyvinylidene Fluoride) and PTFE (Polytetrafluoroethylene), both of which are known for their excellent chemical resistance and ability to handle aggressive fluids. This construction is ideal for fluids that may be aggressive, such as strong acids and alkalis (at certain temperatures).
• Performance: It is engineered to handle high flow rates, making it ideal for environments where large volumes of fluid need to be moved efficiently.
• Environmental Suitability: The pump is ATEX-certified for use in hazardous environments (Ex II2 GD IIB/IIC 95°C). It is also fully groundable, ensuring safety in explosive gas or dust environments.
• Chemical Resistance: It excels in handling strong acids and alkalis, including those at elevated temperatures, which is suitable for many industrial processes, including chemical manufacturing. However, it is not recommended for use with very potent alkalis or concentrated nitric acid.
• Plastic Construction: The use of durable plastic materials (PVDF and PTFE) makes this pump well-suited for certain submersible applications and environments where metal pumps may not be ideal. The plastic design offers resistance to corrosion, extending the pump's life in hostile conditions.

This pump is typically used in industries that require safe handling of aggressive fluids under potentially hazardous conditions, such as chemical processing, mining, or industrial wastewater treatment.
