VD901
Oil Rotary Vacuum Pump [VD Series]
VD series is a direct-drive low noise oil rotary vacuum pump. This pump is suitable for a wide range of applications such as
evaporator, sputtering and food packaging.
Optimized Design Operation for Quiet
Easy MaintenancePump head can be removed without disconnecting the vacuum piping (except VD151, VD201). *See attached figure.Oil level gauge and drain valve accessible for easy oil exchange and daily inspection.
Forced Oil Circulation System Ensures Stable Pumping Speed Below Atmospheric PressureWhen equipped with the optional oil mist trap and oil return mechanism, the VD301, VD401 and VD601 can continuously run at all pressure ranges below atmospheric pressure.
Features
Evaporation, sputtering, and ion plating
Analytical instrument and leak test system
Gas exchange, gas filling, and vacuum insulation
Vacuum drying, freeze drying, vacuum degassing, vacuum packing, vacuum chuck and vacuum molding, etc.
