Flowserve CPM Supply Tank - Manual (Page 7)

Start-Up
1. API Plan 52/ANSI Plan 7352 - open valve to the vent or process
recovery system slowly.
2. API Plan 53/ ANSI 7353 - slowly open valve between reservoir and
external pressurization source. Slowly increase the pressure to avoid
gas ingestion. Check for leaks as unit is being pressurized. Operating
pressure is normally 25 psi above seal cavity pressure. The pressure
gauge on system can be used to monitor system pressure.
3. If system is equipped with cooling coils open valve to allow water to
flow through coils.
4. The main pump can now be started.

Maintenance
During planned plant shutdowns it is recommended that the buffer/barrier
fluid be drained, reservoir flushed and new fluid put in the reservoir. This
will ensure the quality of the buffer/barrier fluid used to lubricate the seals
and to remove any particles that may have accumulated in the reservoir.
When changing or cleaning the glass on armored sight gages (weld pad
level gage) always install new gaskets and retorque bolts to proper
amount. It is also recommended that the bolts be checked and retorqued
prior to first operation. They can come loose during shipping and trans-
port.
