Product Description

Product Introduction
This series of pumps are elementary equipment for pumping air from sealed vessels. It can be used alone, also can be used as the forepump, process pump or titanium pump of booster pump, roots vacuum pump, gas circulation cooling roots pump, oil diffusion pump, and molecular pump.It is applicable to vacuum coating, vacuum heat treatment, vacuum smelting, vacuum tube, bulb, refrigeration, chemicals, packing, forming, health and medical appliances, laboratory, vacuum drying machines and vacuum filtering.

 a. The pump can work continuously in the temperature between 5 to 40 centigrades and inlet pressure less than 1330Pa.
 b. Equipped with gas ballast valve to pump a little water vapor. It can last service life of  the  oil except the 2X-4A type.
c. Dedicated vacuum pump for making neon lights.
d. Many suction holes in the vacuum pump to save electricity.
