TriScroll 320 Series Vacuum Pump
Maintenance
General Information
Agilent TriScroll 300 series pumps are designed to provide years of trouble-free service if maintenance procedures and
intervals are observed. Bearing grease replenishment and tip seal replacement is recommended when pump base pressure
has risen to an unacceptably high level for your application. Bearings, rotary seals and o-rings should also be replaced if
the pump exhibits humming or grinding noises from the bearings.
Maintenance should be performed in accordance with procedures, tooling and materials specified in the manuals listed
below.
