ApplicationPurification or clarification of mineral oils used in marineinstallations and power stations (fuel and lubricating oils).
Working principleSeparation takes place in a solids-retaining bowl that can bearranged for either clarification or purification. In both cases,the contaminated oil is fed into the separator through thecentre, and it is separated by centrifugal force into its variousphases, the heaviest phase (sludge and water) being forcedoutwards to the periphery of the bowl. The accumulation ofsludge is periodically removed from the bowl by hand.
InstallationThe oil is pumped, heated, and separated as shown in thefigure. A liquid seal in the separator bowl prevents the oil fromescaping through the water outlet. If this seal is broken, analarm device is activated. With unmanned engine rooms, thesignals are transmitted to a remote control unit. When theseal is broken, the three-way valve shuts off the oil feed andthe oil is recirculated until the fault is corrected.
Separator model MAB 103B complete with feed/discharge pumpand fittings for connection to a preheater.

Standard designSolids-retaining separator comprisinga frame containing in its lower part ahorizontal drive shaft with friction clutchand brake, worm gear and a verticalbowl spindle. The worm gear is placedin an oil bath.
The bowl is fixed on the top of the spindle inside the space formed by theupper part of the frame and the framehood which also carries the feed anddischarge systems. The frame hood ishinged to facilitate easy access forcleaning the bowl which is of the solid-wall disc type.
