2. Outline of the Pump
2.1 Specification
This oil sealed rotary vacuum pump is a rotary vane pump (hereinafter called Gaede type pump)
in which the pump is directly driven by the motor. Since the pump is small, light, and quite
simply constructed, it is easily maintained and repaired.

Note 1: Ultimate pressure indication by Pirani gauge.
Note 2: Vacuum pump oils have different steam pressures, viscosities, and oil properties depending
on the type. Always use the oil sealed rotary vacuum pump oil specified by us. The use of
other oils will affect the pump’s performance.
Specified oil: SMR-100
Note 3: “G.V.” is an abbreviation for gas ballast valve.
Note 4: The motor voltage is switched between 100-120V and 200-240V by the changeover switch
in the terminal box.
