HPLC1100 Outlet valve pump leaking and bubble issue


I'm encountering ongoing leakage from the outlet valve despite replacing the cap assembly. This persists whenever I close the purge and start a run. Furthermore, when purging to remove bubbles, I'm still observing a significant amount of bubbling in the waste tube.

I'm uncertain if the bubbling relates to the leakage or other issues. Can you suggest which component might be causing this? Or what part could be replaced to resolve these persistent leaks and bubbling?

  • Hi!   you may need to replace the outlet ball valve G1312-60067 and/or the tubing out of the outlet ball valve part number G1311-67301. 

    The air out of the purge vale waste, I don't worry about.  You can cut the line back with a straight blade if it's leaking.  it doesn't affect the runs since the valve is closed.
