Marine Purifier Overflowing, Low RPM, Vibration, Bowl Not Close, Oil in water side Reasons

 Purifier Overflowing
> Sealing water low
> Excessive back pressure
> Fuel temperature high or low
> Oversized gravity disc
> Orifice plate installed wrongly in the inlet side
> Excessive feed rate
> Excessive sludge deposit inside the bowl
> Sealing ring leakage (Between bowl and hood)
> Low rpm or wrong direction
> Leaking three way valve.

Bowl speed low or low RPM
> Brake still on
> Clutch shoes worn
> Clutch friction surface only
> Insufficient clutch shoes
> Bowl full of liquid or sludge
> Bowl height incorrect

Abnormal Vibration
> Bowl out of balance due to buildup of solids
> Incorrect assembly
> Low disc stack pressure
> Spindle bearing springs weak or broken
> Wrong bearings or worm gears

Bowl Does Not Close or Fails To Close Properly
> Ports in base of bowl are clogged
> Sliding piston water outlet clogged
> Worn seal ring on sliding piston
> Seal ring on top of bowl is damaged
> Operating water does not close fully

Oil Discharge on water side 
> Insufficient sealing water
> Incorrect gravity disc
> Reduced oil temperature
> Bowl not properly closed
> Oil supplied too quickly

Water discharge on Oil Side
> Incorrect gravity disc (smaller diameter)
> Too much sealing water supplied
> Oil supplied too quickly
> Bowl falling to open
> Water outlet clogged with sludge

Reduced Feed or no feed
> Feed pump relief valve lifting
> Suction strainer blocked

  1. How is "sliding piston water outlet clogged" responsible for improper Bowl sealing ? Please explain

    1. if only one outlet clogged there may be improper opening of the bowl which leads deposits on seal ring. The final result will be bowl leakage
