Seal flush from internal pumping device through cooler .
Standard flush plan in hot water services ..
Efficient seal cooling with low cooler duty .
Increase fluid vapor margin .
Improve water lubricity
High temperature service ,hot hydrocarbons
Boiler feed water and hot water over 80C (180F)
Clean ,non-polymerizing fluids
Seal cooler and piping must have air vents at highest
elevation - ventbefore starting .When using 682 Seal Cooler
pipe with parallel flow to minimize head loss
Seal chamber requires close clearance throat bushing to
isolate process fluid .Tangential seal gland taps should enter
at bottom and exit at top .Regularly monitor cooler inlet and
outlet temperatures for signs of clogging or fouling
Process fluids with iron should flow through magnetic
separator before cooler
