Design to minimize
potentiel residues
The equipment was designed to minimize potential residue deposits:
by limiting the internal volumes that contain gas,
by injecting N
2
purge on each pump stage to dilute the process
gas (P and H versions),
by regulating the pump temperature and adjusting it to each
process in order to limit gas condensation (P and H versions).
Multi-stage Roots
principle
The ADP pump consists of 5 Roots type stages.
The two rotors rotate without touching each other.
The three stages on the low pressure side are called “
LP stages
” and
the two stages on the high pressure side are called “
HP stages
”.
