1.1 Design
The DRYVAC DV 200, DV 300, and DV 500 are single-stage dry compressing
screw vacuum pumps. They have optimized pumping speeds even at pres-
sures>100mbar.Thesemodelsareespeciallysuitedforshortcycleopera-
tion, e.g. load lock applications.
DRYVAC pumps are equipped as standard with all the typical features
required for applications in the process industry. For example, they have a
gas ballast device.
DRYVAC pumps are designed to provide reliability in harsh process duties.
They are optimized for handling typical gases from the production in the PV
and FPD industry. They excel through their robust design and meet industrial
safety requirements. They are equipped with a purge gas system that makes
possible rotor purge and shaft seal purge.
The DV 200 and DV 300 have the same motor. The required frequency con-
verter is installed at the pump.
All DRYVAC pumps have been prepared for direct fitting of a RUVAC roots
pump.
The pumps are water cooled. They are lubricated either with synthetic oil or
PFPE.
If synthetic oil and PFPE come into contact with each other they will emul-
sify. That’s why the pumps must only be run with the type of lubricant
specified for the pump. If you want to change the type of lubricant please
contact Leybold.
