Seal flush from pump discharge through cyclone separator
Combination of Plan 21 and Plan 31
Solids removal from flush and seal chamber .
High temperature service ,typically less than (350F)
Dirty or contaminated fluids ,water with sand or pipe slag
Seal cooler and piping must have air vents at highest
elevation-vent before starting
When using 682 Seal Cooler ,pipe with series flow to
maximize heat transfer .Cyclone separator works best on
solids with a specific gravity twice the process fluid .Seal
chamber pressure must be nearly equal to suction pressure
for proper flows .Typical failure mode is clogged separator or
pipes -check temperatures at pipe ends .
