YHV-15

The pump is an oil-sealed, two-stage, straight, air-cooled rotary vacuum pump. 

This pump is to improve the product, it is using the German technology and vacuum pump, which its efficient, reliable, low noise, and easy to maintain design, not only in the refrigerating, drying, freeze drying, vacuum degassing, vacuum packaging, vacuum adsorption and vacuum forming, food packaging, printing, spraying, vacuum casting, pv, aviation science and technology, chemical industry, electronics, refrigerator, air conditioner pipeline characteristics and laboratory vacuum operations and systems. But it can not containing too much oxygen, explosive, corrosive to metal, the pump oil will react and gas containing dust particles. 

Features: 

It can be used separately or as a pre-stage pump for other high vacuum pumps or ultra high vacuum pumps. 

The special design gas ballast valve shall be specially designed to prevent pump oil mixing and prolong the use of pump oil. 

High suction efficiency, high vacuum height and long service life. 

4, have automatic check back oil check valve, never return oil; When the pump is stopped, the backreturn oil valve automatically closes the inlet and is applied to the pump (10-100pa). 

Special vacuum drying oven, freeze-drying machine, printing machine, coating machine, glove box, refrigerator assembly line. 

6, can match small aperture switch joint, KF interface, flange interface; 

When suction contains vapor, particles and corrosive gases, auxiliary equipment, such as condenser and dust collector, should be installed in the inlet of pump.
