The Alfa Laval MAB 103 Centrifuge is a solid-retaining (aka solid bowl; manual-clean), disc-stack centrifuge ideal for the continuous, three-phase separation of fuels, such as diesel, biodiesel, and turbine lube oil.
With a 1 HP Motor, the MAB 103 centrifuge has a bowl RPM of 8,600 and can process 3 GPM of Diesel Fuel or 1 GPM of Turbine Lube Oil.

| Rated Capacity | 3 GPM on 13 cSt Diesel Fuel |
| Sludge Space | 0.14 Gallons |
| Motor HP: | 1 HP |
| Voltages: | 230 / 460 V |
The Alfa Laval MAB-103 is a purifier type disc-stack centrifuge. It is designed to separate water (moisture) and fine sediment from mineral oil and lubricating oil. It is primarily used for purifying fuels such as diesel, kerosene, etc. The MAB-103 is also used for separating water and fine sediment from lubrication oil, hydraulic oil, and other mineral oil.
For offshore applications, the centrifuge is configured similar to the OCM-103-Ex configuration with explosion-proof ATEX Zone II.
The fuel or mineral oil is fed into the rotating bowl of the MAB-103 centrifuge. The bowl exerts a high g-force (8,500 Gs) on the process fluid. The centrifugal force causes rapid sedimentation of the solid particles.
This separated sludge should be manually evacuated by the operator. The heavy phase (water) phase also settles out and exist the bowl through the separate outlet.
The Alfa Laval WSB 203 Centrifuge is a solid-retaining (aka solid bowl; manual-clean), disc-stack centrifuge ideal for the continuous, three-phase separation of water-based industrial fluids like machining coolant and washer fluid.
With a 1 HP Motor, the WSB 203 centrifuge has a bowl RPM of 8,600 and can process 1 GPM of water-based synthetic coolant.
| Model Type | Alfa Laval WSB 203 70 |
| Rated Capacity | 1 GPM on Parts Washer Fluid |
| Sludge Space | 0.14 Gallons |
| Motor HP: | 1 HP |
| Voltages: | 230 / 460 V |
The Alfa Laval WSB-203 is a concentrator version of the MAB-103 disc-stack centrifuge. It is specifically designed to concentrate oil from water-based industrial fluids such as machine coolant, washer fluid, parts washer solvent, water-soluble cutting oils, de-oiling of split emulsions, 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-based fluid and heavy solids to the bowl wall. The solids accumulate here, and the water-based 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.
