General Information

Agilent (Varian) TriScroll 600 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 are
recommended when the 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 will keep this water from
impacting bearing life.
