Mechanical seal flushing plan
Thread Content
As shown in the figure, what is the flushing scheme?
Is there a nitrogen source on site? If so, it is PLAN11+53A; otherwise, it is PLAN11+52
It’s not completely captured; it seems to be PLAN13+52 or 53A
I took another look at the pictures; the flushing for internal sealing seems to not be Plan11
It is PLAN11+52. You are correct
Doesn’t Plan11 go from the pump’s outlet, through the flow control orifice plate, to the sealing chamber? Is the inlet on top of this pump and the outlet at the bottom?
Yes, but the device specifications show PLAN11+52. There is indeed an anomaly
Based on the pipeline diameter, it can be determined whether the inlet and outlet are from the sealing chamber to inlet PLAN13+52 or 53A
I just searched on Baidu – isn’t 13 used for vertical pumps?
