Tip Seal Replacement
General Information
Vacuum Technologies TriScroll 300 series pumps will provide years of trouble-free service if
maintenance procedures and intervals are observed. Bearing grease replenishment and tip seal
replacement is recommended when the pump base pressure rises to an unacceptably high level for
your application. Replace bearings, rotary seals and O-rings if the pump bearings exhibit humming or
grinding noises. Main bearing life may be shortened if your application requires the pumping of high
quantities of water vapor. Use bearing purge to keep this water from impacting bearing life.
