Product Name:
VDN301 / VDN401 Oil Sealed Rotary Vane Vacuum Pump

● Low noise:Optimized design achieved quiet running.

● Easy maintenance:Pump body can be removed without disconnecting the inlet vacuum pipes.

Checking, adding and changing oil are done at the same side of the pump to facilitate greater ease in performing routine maintenance and inspection. A variable oil volume is adopted to extend the complementary time of oil.

● Forced oil circulation system ensures stable pumping speed around atmospheric pressure

When equipped with optional oil mist trap and oil return mechanism, these pumps can run continuously at pressures equal to or below atmospheric pressure.

Applications

•  Evaporation, sputtering and ion plating.

•  Gas substitution, back-filling and vacuum insulation.

•  Vacuum drying, freeze drying, vacuum degassing.

•  Analytical instruments and leak testers.

•  Vacuum packing, vacuum adsorption and transport,vacuum molding and vacuum casting.
