Choosing the Right Pump Seals

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) (0905-1420))
and Wash Seal PE (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
NOTE
above 200 bar their lifetime is reduced significantly.
