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:

* origin products-based, optimized design, easy for maintenance and repair;

* the original 3-cylinder mechanism has been improved to a upgraded 2-cylinder one, convenient for maintenance and repair; side cover on the cylinder body for a convenient cleaning operation to the long and short cylinders;

* oil circulation system equipped with auto control operation mechanism, needn't bother to cut off the oil input valve after the machine turning off;

* altered the bearing position a bit outside so elongated its service life;

* with a protective shaft sleeve, quite reduced the wearing out of primary shaft;

* after elaborate dynamic poise adjustment to rotary parts, ensured a stable running and low noise performance;
