Choosing The Right Pump Seals - Agilent Technologies 1260 Infinity VL User Manual

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). For normal phase
applications, these seals have less abrasion compared to the standard seals.
Polyethylene seals have a limited pressure range of 0 – 200 bar. When used above 200 bar
N O T E
their lifetime is reduced significantly. DO NOT apply the seal wear-in procedure with PE
seals.
