Vacuum pump -Industrial vacuum system: 
Roots pump vacuum system with rotary piston vacuum pumps 
JZP2H type Roots-Rotary piston vacuum system consists of the main pump i.e. ZJP type Roots 
vacuum pump and backing pump i.e. rotary piston vacuum pump. 
It has not only the generally vacuum feature,also has some advantages as follows, savingenergy, 
high ultimate vacuum with high pumping speed and creditable quality . It can pump not only the 
commom gas but also the gas that contains no solid and corrosion. 
This vacuum system used widely in chemical ,electronic, pharmaceutical, vacuum coating industry. It 
is the best choice in the vacuum industry.
