BOC Edwards have pioneered the use of dry vacuum pumps in some
the most harsh applications. With over 10 years experience and more
than 60,000 Drystar pumps installed worldwide, this technology now
becomes available to the industrial user.
Our GV Drystar pumps are a new series of dry vacuum pumps designed
to perform reliably and economically in a range of demanding industrial
applications. The GV pumps have displacements from 90 m3h-1 to 540
m3h-1. Benefits of switching to BOC Edwards GV
series dry pumps
Repeatable pumping performance.
No degradation in speed or pressure-no oil contamination.
Fit and forget performance.
No user intervention for 1 year.
Good dust handing using
Claw mechanism is self cleaning and will pass micron size Particulate.
Noise and Vibration reduced.
Oil free exhaust fumes.
No oil reclaim. Clean
environment around exhaust area.
Increased up time.
Maintenance cost savings.
No oil associated issues or frequent rebuilds.
pumping with no detrimental effects to the pump.
Highly reliable dry mechanism, proven in 60,000 installations.
A Inlet exposed C Outlet exposed
B Inlet isolated D Outlet isolated
The design of the BOC Edwards GV dry pumps is based on the well-proven
claw technology for dry pumps. Two pairs of claw shaped rotors
on two shafts rotate in opposite directions to trap and compress
the process gas which flows along the axis of the shafts between
the claw pairs.
During each complete rotation of the claws, first the inlet port
of each claw pair is exposed (to admit gas to the pump), then
both the inlet and outlet are isolated (to trap and compress the
gas), and then the outlet is exposed(to expel the compressed gas).
The claw mechanism offers the followingfeatures:
Dry operation, non
Self valving -the pump
can deliver to atmospheric
Pressure short gas
path -better particulate handing
High process temperature
- excellent water vapour handling
