CAUTION: Nonmetallic pumps and plastic components are not UV stabilized. Ultraviolet radiation can damage these parts and negatively affect material properties.
Do not expose to UV light for extended periods of time.
Santoprene ® Injection molded thermoplastic elastomer with no fabric layer. Long mechanical flex life. Excellent abrasion 212°F -10°F
resistance. 100°C -23°C
Virgin PTFE Chemically inert, virtually impervious. Very few chemicals are known to react chemically with PTFE: molten alkali metals, turbulent
liquid or gaseous fluorine and a few fluoro-chemicals such as chlorine trifluoride or oxygen difluoride which readily liberate free fluorine at 212°F -35°F

Maximum and Minimum Temperatures are the limits for which these
materials can be operated. Temperatures coupled with pressure affect the
longevity of diaphragm pump components. Maximum life should not be
expected at the extreme limits of the temperature ranges.
