Hi all,
I have a centrifugal pump with seal plan 53B running parallel 2 pumps (Pump A and B)
During switch over from pump B to C, pump A still running but shaft movement changes from 0.2 to -0.1 and back to 0.2 again after successfully run pump C (current running pump A & C).
After that, seal DE has low pressure and had topped up for 7x in 8 hours.
Process parameters remain stable.
Anyone knows what the problem is, since the shaft movement back to normal but seal pressure not.
Thanks in advance
