Alfa Laval MAB series centrifuges are disc-stack-type centrifuges with a solid bowl. A solid-bowl centrifuge implies that the separated solids must be manually removed periodically.
These are very simple centrifuges, with the main disadvantage of MAB-type centrifuges being the 'manual cleaning' operation that requires the centrifuge to be stopped.
The Alfa Laval MAB Series Centrifuges are solid-retaining (aka solid bowl; manual-clean) disc centrifuges ideal for the continuous, three-phase separation of fuels, such as diesel, biodiesel, turbine lube oil, and hydraulic oil.
The Alfa Laval MAB centrifuge is a purifier version of a disc-stack centrifuge. It is specifically designed to purify water from mineral oils and fuels such as diesel fuel, turbine lube oil, hydraulic oil, engine oil, etc.
The process fluid is fed to the rotating centrifuge bowl from the top (1) and is sped up in the distributor (2). It then enters the disc stack (3), and it is between the discs that the separation occurs.
The high centrifugal force pushes the water and heavy solids to the bowl wall. The solids accumulate here, and the water fluid travels over the top disc (4) and exits the bowl through the open outlet (5). The oil (light phase) is moved towards the bowl center and exits the bowl through the open outlet (6).
The centrifuge needs to be periodically stopped for manual removal of separated solids. The rotating bowl assembly is mounted on a vertical 'bowl-spindle' (7). A horizontally mounted motor rotates the spindle via a worm gear.
