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.

Advantages:

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)

Packaging  Details: Export Standard Packing.

Delivery  Detail: 60 days after receipt of payment.
