Agilent Varian Part Number: S4829001.
This is an Agilent Varian OEM replacement orbiting spacer ring for the TriScroll 600 dry scroll vacuum Pump.
Part #2 shown in the third picture (highlighted in yellow).
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.
