Roots vacuum pump

high vacuum degree up to 0.3Pa; simple maintenance & repair based on optimized design; auto-control oil system long-life bearing

Rotary piston vacuum pump is suitable for air and other ordinary gases, with a gas ballast valve, witch could be applied to pump condensable gases (such as vapor). The pump should be equipped with appropriate accessories if the gas pumped has the following features, such as rich in oxgen, explosive, corrosive to ferrous metal and chemical reactive with the vacuum pump oil. This series of pumps could be operated in single unit or act as the pre-process pumping unit for the next high vacuum pumps, such as diffusion or roots pumps. It is widely used in the industries of vacuum coating, vacuum heat treatment, vacuum impregnation, vacuum smelting, vacuum metallurgy, vacuum drying, molecular distillation and altitude simulation testing.  

Features:

* high vacuum degree, up to 0.3Pa value;

* no any leakage to the improved oil seal;

* low vibration and noise. stable running;

* with 4 national patents

patent 1: clearance auto-compensator for lubricating sliding track

patent 2: throttling set for oil-channel 

patent 3: samll oil tank design

patent 4: oil sealing special design
