Applications

The Alfa Laval MAB-104 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-104 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-104-Ex configuration with explosion-proof ATEX Zone II.

Modifications

The MAB 104 centrifuge needs modifications for specific applications such as hazardous area installation, processing of water-based fluids, oil, or fuel. The following is a list of common modifications by Dolphin Centrifuge based on the specific application.

Centrifuge Modification Application / Purpose
Direct Drive (Replace Friction Clutch) Explosion Proof Configuration
Non-Sparking Friction Blocks Explosion Proof Configuration
Pump Reconfiguration (Capacity) Lube Oil to Light Fuel OR Light Fuel to Lube Oil
Seals Elastomer (Viton / EPDM) Biodiesel, Hemp Ethanol, Corrosive Chemicals, etc.
Gear Pump Replacement Water Based Fluids (Steel Gear Pump not Suitable)
Operating Frequency Conversion Adapt to Operating Voltage Frequency (50 or 60 Hz)
Special Motor Adaptation Single Phase (110 V or 220 V) Voltage Application
Bowl Parts Material Upgrade Convert Bowl Parts to Stainless Steel (Aqueous Ammonia)
Purifier to Clarifier Convert from 3-Phase to 2-Phase Mode (Clarifier)

Operation

The process oil 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 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.

WSB 104 Applications

The Alfa Laval WSB-104 is a concentrator version of the MAB-104 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.

WSB 104 Operation

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.

Frequently Asked Questions

What is the capacity of the Alfa Laval MAB 104 centrifuge?
The Alfa Laval MAB 104 centrifuge can process 6 GPM of 13 cSt diesel fuel, 5 GPM of turbine lube oil, or 4 GPM of hydraulic oil. The WSB 104 variant processes 2 GPM of water-based synthetic coolant. Actual capacity depends on fluid viscosity, contamination levels, and desired separation quality.
What is the difference between the MAB 104 and the WSB 104?
The MAB 104 is a purifier designed to separate water and sediment from mineral oils and fuels such as diesel, lube oil, and hydraulic oil. The WSB 104 is a concentrator version designed specifically for water-based industrial fluids like machining coolant and washer fluid. A key construction difference is that the WSB 104 features all-stainless-steel bowl components (distributor and top disc are 316L Duplex Stainless Steel) and cast iron top covers instead of the aluminum alloy (Silium) covers used on the MAB 104.
Can the MAB 104 be used in explosion-proof environments?
Yes. The MAB 104 can be configured for explosion-proof operation with modifications including direct drive (replacing the friction clutch) and non-sparking friction blocks. For offshore applications, it is configured similar to the OCM-104-Ex configuration with explosion-proof ATEX Zone II certification. Dolphin Centrifuge regularly supplies explosion-proof MAB 104 modules for offshore platforms and refineries.
What modifications are available for the MAB 104?
Common modifications include explosion-proof configuration (direct drive, non-sparking friction blocks), pump reconfiguration for different fluid viscosities, seal elastomer changes (Viton or EPDM) for biodiesel or corrosive chemicals, gear pump replacement for water-based fluids, operating frequency conversion (50 or 60 Hz), single-phase motor adaptation (110 V or 220 V), bowl parts material upgrade to stainless steel for aqueous ammonia applications, and purifier-to-clarifier conversion to change from three-phase to two-phase separation mode.
What is the Dolphin Centrifuge equivalent of the Alfa Laval MAB 104?
The Dolphin DMB-007 is the functional equivalent of the Alfa Laval MAB 104 centrifuge. The DMB-007 is a complete system module rated at 6–8 GPM on diesel, built around the same centrifuge bowl size as the MAB 104. The module includes a pre-heater, feed pump, PLC controls, and starter in a skid-mounted package. Contact Dolphin Centrifuge at (248) 522-2573 for specs and pricing.
