API Plan 54 w/pumping ring
API Plan 54 w/pumping ring
(OP)
What is disadvantage of having an axial scroll pumping ring on O/B seal of dual seal...but have a plan 54? This is a horizontal pump..if the external pump is creating flow of say 3GPM and the pumping ring is <3GPM, is this hindering the flow rate? What would happen?

I would have several concerns:
1) If the pumping ring is less effective than the Plan 54 Pump, it may inhibit the flow.
2) If it is more effective (unlikely) then it will be starved and therefore will likely cavitate.
3) Irrespective of the above, it may well be producing unnecessary heat through viscous shear.
I would remove it if possible.

Just for my personal knowledge..could you explain your point #2..how would cavitation occur?
