　　What

　　Seal flush from pump discharge through cyclone separator

　　Centrifuged solids are returned to pump suction .

　　Why

　　Seal chamber heat removal .

　　Solids removal from flush and seal chamber .

　　Where

　　Dirty or contaminated fluids ,water with sand or pipe slag

　　Non-polymerizing fluids

　　Preventative Maintenance

　　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 .
