MMB 305


MMB 305 Solids-Retaining Centrifugal Separator

Machine Application

The MMB 305 high speed disc stack centrifuge is designed for purification or clarification of distillates, marine diesel oils, lubricating oils, hydraulic oils, and various mineral oils used on-board marine installations and in industrial applications. The MMB 305 oil separator is specifically designed for cleaning of mineral oils from water and solid particles (sludge).

Separator Design

The MMB 305 separator consists of frame lower part, intermediate part, frame top part, and frame hood. The separator is driven by an electric motor, friction coupling, flat belt, and vertical drive shaft. The motor drives the friction coupling which drives the flat belt, ensuring a gradual start, preventing overload. The MMB 304 separator requires an independent oil feed pump.

The bowl is fixed onto the vertical drive shaft situated in the top part of the frame. The frame hood is easily removed to enable easy of access when cleaning or carrying out maintenance. The separation process takes place in the rotating solids-retaining bowl.

The cleaned oil is discharged continuously, while solid particles are collected in the separator and have to be removed manually from the bowl regularly by hand.
