The MAB 104 is a solids-retaining centrifuge for clarifying or purifying of mineral oils. It’s used for separating fuel and lubricating oils, hydraulic, running in and metal working oils. It has a solids-retaining separator comprising of a frame containing in its lower part a horizontal drive shaft with friction clutch and brake, worm gear and vertical bowl spindle. The worm gear is placed in an oil bath. The bowl is fixed on top of the spindle inside the space formed by the upper part of the frame and the frame hood. The frame hood is hinged to facilitate easy access for cleaning the bowl, which is of solid wall disc type. The separator is equipped with a built-in feed and discharge pump. The system may require other ancillary equipment. The robust design has the benefits of easy installation, operation and maintenance. The flexible bowl may be used either as purifier or clarifier.
