Roots Vacuum pumps,often referred to as mechanical boost pumps,are ideal for evacuating gas from sealed containers.being unable to compress against atmospheric pressure.Roots pumps are normally used in combination with backing pumps such as rotary vane pumps,liquid ring pumps and oil-sealed rotary piston vacuum pumps.They find wide application in the fields of metallurgy,chemical industry,electronics and textile,etc.

Design features:

The pumped gas is delivered from top to bottom vertically.

High pumping speed in a wide pressure range.

Fast starting.

Insensitive to dust and water vapour contained in gas.

Oil-free pump chamber helpful for obtaining clean vacuum.

Weak vibration and low noise.

Low drive power and low cost for running and maintenance.

NOTES:

DO NOT evacuate liquid media.

DO NOT evacuate inflammable or explosive gas.

Backing pumps should be used.

It is suggested to equip a fiter at the in let if the gas to be pumped contains solid particles.

Advantages:

The series of roots pumps,as a result of new technology in the structural design and more advanced and reasonable manufacturer process,bear the following advantages:

Weak vibration and low noise:

Due to high-accurate dynamic balance tachnology,helical gears made by a specialized manufacturer and imported bearings.

Effective elimination of oil leak:

BY means of imported shaft seal and labyrinth piston design.

Evacuation of high boiling point working media(with the exception of model ZJP-1200):

BY means of protection gas syatem.

Can do overload protection can be achieved:

BY seting relief valve.

Easy testing and measuring:

BY use of special ports at inlet and outlet for testing and and measuring.

Connection of the system:

Through arrangement of severa exhausting ports for different modes such as side or bottom evacuation.
