Features
- These pumps use no oil in the pumping chamber resulting in stable performance even when evacuating water vapor or solvent vapors.
- The pumping lobes and chamber walls are made of a strong, lightweight aluminum alloy with a special coating which provides excellent corrosion resistance and surface protection inside the pump. Abrasion and corrosion (wear and tear) inside the pump is greatly reduced.
- The PRC-A series is switched on at the same time as the roughing pump. Starting this pump simultaneously at atmospheric pressure shortens evacuation time considerably.
- The exhaust port location on the pump can be changed from the vertical to the horizontal direction if desired. This feature enhances design flexibility and makes very compact system layouts possible.
