Cyclone separators are typically used in an API Plan 31 arrangement and incoporated in the seal flush line (API Plan 11 ) from the discharge of the pump.
This is designed to supply clear flushing fluid for lubrication to mechanical seal in seal chamber. This is
fitted in between pump discharge and seal flush port line, to remove abrasive particles which can cause damage to
mechanical seal and reduce its recommended operational life. Due to centrifuging action of the fluid, cyclone is
generated in the cyclone separator and 80% of abrasive particles are separated and sent back to pump section.
