2X series rotary vane vacuum pumps is the basic equipment used to seal the airtight containers for the extraction of gas.

Applications:

can be used alone, and also can be used as prepump.

Can be use in the indusries such as vacuum metallurgy, vacuum welding, vacuum casting, vacuum drying, chemical and pharmaceutical, electric vacuum devices. Long continuous work is enabled under the conditions of environmental temperature 5°C-40°C and inlet pressure less then 1330 Pa.

Can not be used to extract high oxygen, toxic, explosive, corrosive, chemical reaction responding to pump oil and dust contained gases or used as delivery pump.

The time of continuous work under the inlet pressure of 6650Pa to high atmospheric pressure can be no more than 3 minutes.
