2.7 Connecting the purge
gas
The MAG is equipped with a purge gas connector. To
ensure protection of the pump a constant purge gas
throughput of 30 to 40 sccm is required. You may use a
flow controller to ensure the flow. Inadequate purge gas
flow voids the warranty.
Connect purge gas to the VCR nut 1/4“ as shown in Fig.
20.
Warning
Monitor the purge gas continuously.
Insufficient purge gas flow can result in:
- Process gases entering the motor and
bearing area of the MAG
- Process gases escaping from the purge
gas connector
- Humidity entering the pump.
