Seals And Pistons
Agilent TechnologiesPump seals should be replaced when there are leaks on the bottom of the pump head, when retention times are inconsistent, or when the pressure ripple is unstable. Each time the seals are replaced, the pistons (plungers) should be examined for scratches. Scratched pistons will cause small…
