When to Use Alternative Seals

When to Use Alternative Seals
The standard seals for the binary pump can be used for most applications.
However applications that use normal phase solvents (for example, hexane)
are not suited for the standard seals and require a different seals when used
for a longer time in the binary pump.
For applications that use normal phase solvents (for example, hexane) we
recommend the use of the polyethylene seals, part number 0905-1420 (pack
of 2). These seals have less abrasion compared to the standard seals.
N O T E Polyethylene seals have a limited pressure range 0–200 bar. When used above
200 bar their lifetime will be significantly reduced. DO NOT apply the seal
wear-in procedure performed with new standard seals at 400 bar.
