Agilent Varian SD 450 / 451 Rotary Vane Vacuum Pump - REBUILT
Series 91 through 451 pump models with the following main characteristics:
- A direct drive motor makes them very compact.
- An electrically insulated fold-away handle is used for easy carrying.
- An anti-suckback system ensures the tightness of the pump during accidental or voluntary shutdowns.
- A gas ballast enables the pumping of condensable vapours (except for CP series).
- The universal three-phase or singlephase motor can be disassembled independently of the rest of the pump, without needing to drain the oil case.
- On the oil case, a vertical sight gloss can be used to inspect the oil level easily when filling the tank and during the operation of the pump.
- A neutral gas purge is used to degas oil and dilute pumped gases on CP series models.
If the requested voltage is not in stock then we will purchase a new motor and split the cost with you. They run on various vacuum pump oils.
