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 above 200 bar
their lifetime is reduced significantly.
