Seal flush from pump discharge through orifice and cooler .
Cooler added to Plan 11 flush increases heat removal
Reduce fluid temperature to increase fluid vapor margin .
High temperature service ,typically less than (350F).
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 series flow to maximize heat transfer .
Use an orifice with a minimum 3 mm ( 1/8inch )diameter .
Calculate flow rates to size orifice for adequate seal chamber
flow .Increase boiling point margin with proper orifice and
throat bushing sizing .Regularly monitor cooler inlet and
outlet temperatures for signs of clogging or fouling
