Purge Valve

Common to all 1100/1200 pump modules, the purge valve has a gold seal held in place with a plastic cup The most frequently replaced item in the 1100/1200 Series pumps is the purge valve PTFE frit, which can clog with seal material or solvent particulates When replacing the frit, remember that…

Seals And Pistons

Pump 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 leaks…

Outlet Ball Valve

Before exchanging the outlet ball valve, try cleaning it in a sonicator by placing the valve in an upright position (onto the plastic cap) in a small beaker with alcohol. Sonicate for 5 to 10 minutes. The 1100/1200 Series binary pump has a different outlet ball valve which includes a sieve.
