Edwards GXS 160/1750 - Figure 13 DP Clean Assembly for the Pump Only Systems

The pneumac regulator is pre-set to 50 ± 5 psig in the factory and does not need to be
adjusted. The pneumac regulator is shown in Figure: DP clean assembly for the pump
only systems, item 5 for the pump‑only systems. For pump and booster combinaon
systems, the regulator is contained within the pump enclosure.
To use an inert gas in place of atmospheric air as the DP clean purge gas, remove the air
lter and in its place connect up the inert gas supply. For pump and booster
combinaons, the air lter is on the rear pump panel (refer to Figure: The controls/
connectors on the rear of the pump (system with rear exhaust and castors/levelling feet
ed), item 12). For pump‑only systems, refer to Figure: DP clean assembly for the pump
only systems, item 1. Refer to DP clean high ow purge/solvent ush opon on page 27
for informaon about ngs and typical purge gas ows.
A solvent sucon pipe is provided with the pump. When only performing a high ow
purge procedure, the solvent sucon pipe will not be needed. When performing a
solvent ush, t the solvent sucon pipe only when ready to perform the DP clean
procedure. For pump and booster combinaons, the solvent ush uid connecon is on
the rear pump panel (refer to Figure: The controls/connectors on the rear of the pump
(system with rear exhaust and castors/levelling feet ed), item 11). For pump‑only
systems, refer to Figure: DP clean assembly for the pump only systems, item 2.
A PDT is required to operate the DP clean high ow purge and solvent ush.
