Installation
Pumps without purge gas valve
(MAG W 830 C, W 1300 C, W 2200 C,
W 830, W 1300, W 2200, W 2800)
The MAG has a purge gas inlet VCR nut 1/4“ or DN 16 KF. The required
purge gas flow is 36 sccm ± 5 sccm.
The pump needs an external purge gas control.
The optional purge gas Tee allows the throttled inlet of purge and venting
gas. A purge gas pressure of 1.5 bar (abs.) will provide the required flow of
36 sccm ± 5 sccm.
The Tee and the the purge vent valve can be mounted to the MAG W 830
C, W 1300 C, W 830, W 1300, W 2200 and W 2800.
The pumps without C in the name are not suitable for pumping
corrosive and aggressive gases even when they are operated with
purge gas.
