View SpecificationsFrequently Asked Questions
Find answers to common questions about our non-metallic AODD pumps.
What is the difference between Polypropylene and PVDF?
PVDF offers superior chemical resistance and higher temperature capability compared to polypropylene. PVDF is recommended for strong acids, chlorinated solvents, and high-temperature applications. Polypropylene is cost-effective for general chemical service with moderate temperatures.
When should I choose Conductive PVDF?
Conductive PVDF is required for handling flammable or explosive fluids where static electricity buildup poses a safety risk. It provides static dissipation properties and is ATEX certified for hazardous area installations.
What is the maximum temperature for non-metallic pumps?
Polypropylene pumps are rated for up to 80°C, while PVDF and Conductive PVDF pumps can handle temperatures up to 120°C. For higher temperature applications, consider metallic construction options.
Can these pumps handle abrasive slurries?
Yes, non-metallic AODD pumps can handle abrasive slurries when equipped with appropriate diaphragm materials like Santoprene. The slow, gentle pumping action minimizes wear on components.
Are FDA approved models available?
Yes, we offer FDA compliant models with PTFE diaphragms and sanitary connections suitable for food, beverage, and pharmaceutical applications. Contact our team for specific requirements.
