Rotary vane 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, electronics, semiconductor, electric luminaries, food packing and refrigeration.  

Features:

* high vacuum pumping efficiency, high vacuum degree, long service life;

* high performance in pumping vapor;

* low vibration and noise;

* fashional appearance design;

* adopting new matierals and technics;

* inner-built auto oil check valve;

* inner-built circulation system for pressure oil;

* convenient, multi-step gas balllast valve control;

* simpale mechanism, easy opeation and maintenance;
