Optimizing Performance

Choosing the Right Pump Seals

The standard seal for the pump can be used for most applications. However

applications that use normal phase solvents (for example, hexane) are not

suited for the standard seal and require a different seal when used for a longer

time in the pump.

For applications that use normal phase solvents (for example, hexane) we

recommend using polyethylene pump seals (PE seals (pack of 2) (p/n

0905-1420)) and Wash Seal PE (p/n 0905-1718). These seals have less

abrasion compared to the standard seals.

NOTE

Polyethylene seals have a limited pressure range of 0 – 200 bar. When used above 200 bar

their lifetime is reduced significantly. DO NOT apply the seal wear-in procedure performed

with new standard seals at 400 bar.
