Table of Contents

Overview

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.

Applications

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 lubricating oil, hydraulic oil, and other mineral oils.

Explosion Proof Configuration

The installation of the MAB-103 centrifuge in hazardous areas requires the centrifuge system to be specially designed and configured with an explosion proof motor, direct-drive transmission (replace friction clutch) and classified field sensors.

The control system upgrade includes a NEMA 7 electrical enclosure, cables, conduits, and glands suitable for the specific zone of the centrifuge installation.

We configure our MAB-103 centrifuge similar to the Alfa Laval OCM-103-Ex configuration with explosion-proof ATEX Zone II for offshore applications.

Modifications

The MAB 103 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 ModificationApplication / Purpose
Direct Drive (Replace Friction Clutch)Explosion Proof Configuration
Non-Sparking Friction BlocksExplosion 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 ReplacementWater Based Fluids (Steel Gear Pump not Suitable)
Operating Frequency ConversionAdapt to Operating Voltage Frequency (50 or 60 Hz)
Special Motor AdaptationSingle Phase (110 V or 220 V) Voltage Application
Bowl Parts Material UpgradeConvert Bowl Parts to Stainless Steel (Aqueous Ammonia)
Purifier to ClarifierConvert from 3-Phase to 2-Phase Mode (Clarifier)

Operation

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 down to 0.5 Microns.

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.

Alfa Laval WSB 203 70 Manual Clean, Concentrator Disc-Stack Centrifuge

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.

Applications

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.

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.

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.
