gas which is compatible with
process
Typically 170 slm (for the
GXS160 and GXS250 systems)
and 185 slm (for the GXS450
and GXS750 systems) at
atmospheric pressure at the
purge inlet connection
High flow purge air filter

DP clean solvent flush
fluid inlet connection
3/8 inch BSP male
DP clean solvent suction
pipe connection
3/8 inch BSP female
Notes:
1. The high flow purge/solvent flush kit is available as an option.
2. The DP clean solvent suction pipe is supplied with the pump but not fitted.
2.8 External evacuation system
The pumpdown performance on dry pumping systems fitted with mechanical boosters
can be further enhanced by the use of an External Evacuation System (EES) kit. The EES
kit will only provide performance improvement on pumpdown cycles lasting less than
30 seconds to pressures below 0.1 mbar. The EES kit must only be used on clean
applications.
