Maintenance
General Information
Agilent TriScroll 800 Inverter pump is 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. Main bearing life may be shortened if your application
requires the pumping of high quantities of water vapor. Use of the bearing purge kit (PTSPURGEKIT) mentioned earlier will
keep this water from impacting bearing life.
Maintenance should be performed in accordance with procedures, tooling and materials specified in the manuals listed
below.
