Deep blue small pump, question
Thread Content
It is a dark blue small pump used to transport a medium with a high ammonia content. The pump has been shut down and its impeller removed; the fluid is now forced out under the pressure generated by the equipment itself. I would like to know whether this approach has any impact on the pump’s mechanical seal and the pipeline used for flushing the seal. Is it necessary to isolate the pipeline used for flushing the seal? The mechanical seal flushing method is Plan21
It’s similar to ours; we have hydrogen sulfide. Is there a way to connect fresh water at the pump inlet for flushing and displacement?
No need. Plan21 is enough.
If the flushing pipeline of Plan21 is isolated, will it have an impact on the pump’s seal? The pump itself does not perform any work; it is just a simple passage.
It can be replaced with a non-corrosive medium~without any impact；
During the pump shutdown period, Plan21 can be stopped
