Supercharge Your Roughing Pump 

Mechanical booster pumps (a.k.a. "Roots Blowers") can be used on the inlet of primary roughing pumps, such as oil-sealed rotary vane pumps, dry pumps, scroll pumps or water ring backing pumps to improve the pumping speed in the 75 Torr to 75mTorr pressure range, where pumping speeds of roughing pumps often falls off dramatically. The PRC-A roots type pump series is designed for general purpose, semiconductor and liquid crystal display processes which require extreme cleanliness of the pump, both inside and out. The PMB-040C & 060C models are well suited for the large volume evacuation required by vacuum heating and vacuum melting furnaces, and other large volume pumpdown work such as space simulation chambers

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.
