Edwards mechanical high vacuum pumps are powerful, two-stage direct-drive
workhorses, pumping 75, 113 or 190 liters per minute (at 60 Hz operation)
to clear out chambers and maintain vacuum with ease. They offer as standard
features: fan-cooling, low noise operation, minimum vibration,
built-in flap to minimize fluid backup into the chamber,
Viton® fluoroelastomer seals, wide oil level tolerance, pressure drain
facility, and constant oil lubrication with positive oil feed. Pumps are
prepared and charged with either hydrocarbon or perfluoropolyether pump
fluid such as Fomblin® or Krytox® fluid prior
to shipment. |
