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 (0905-1420 (PE seal (pack of 2)) ) and 0905-1718 (Wash Seal PE) . For normal phase applications, 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.
