Mechanical Booster Pump

PMB-C Series

PMB-C

アルバック

By using together with dry vacuum pumps, oil rotary vacuum pumps or water-sealed vacuum pumps, mechanical booster pumps can increase pumping speed in the range between 10kPa to 0.1 Pa, where roughing pump pumping speed drops.

Features

  • These pumps use no oil in the pumping chamber resulting in stable performance even when evacuating water vapor or solvent vapors.
