2A.7 Optional Seals Typically, the general seal provided with your pump will satisfy<br />
your application’s requirements, including SFE or other applications<br />
which use carbon dioxide. However, certain solvents and/or<br />
conditions require the cylinder seal be changed to facilitate the<br />
application. Table 2A-6 is provided to help you select the correct<br />
seal for your pump and application requirements.<br />

202-9990-27<br />
This seal is best suited for applications which require temperatures between 50°C and 100°C. Its<br />
chemical compatibility is similar to that of the general seal.<br />

202-9092-75 202-9092-06 202-9092-56 N/A<br />
This seal may provide better sealing at lower pressure. Its chemical compatibility is similar to that<br />
of the general seal.<br />

202-9090-77 202-9094-06 202-9094-56 N/A<br />
This seal has better wetting properties, which makes it a good choice for aqueous solutions. It is<br />
also the best choice for electrochemical detection.<br />
Note: This seal requires a special break-in procedure before installation. See Section 5.3.2.<br />
0-275.8 bar White, virgin<br />
PTFE<br />
This is the only seal which is recommended for ammonia.<br />
Note: Call the factory for seal availability for the 65D pump.<br />
