Seal flush from pump discharge through cyclone separator
Centrifuged solids are returned to pump suction .
Seal chamber heat removal .
Solids removal from flush and seal chamber .
Dirty or contaminated fluids ,water with sand or pipe slag
Cyclone separator works best on solids with a specific gravity
twice the process
Seal chamber pressure must be nearly equal to suction
pressure for proper flows
Piping should not include an orifice and is not expected to
vent the seal chamber .
Typical failure mode is clogged separator or pipes - check
temperatures at pipe ends .
