Alfa Laval MAB Centrifuge
The Alfa Laval MAB centrifuge is crucial to many industrial processes and is known for its high performance and reliability. If you’re not sure what it is or how it works, read on for more information. We’ll cover the basics of what the Alfa Laval solid bowl centrifuges are used for and explain how the Alfa Laval MAB centrifuge fits into things.
How does an Alfa Laval MAB centrifuge work?
The Alfa Laval MAB disc stack centrifuge is a centrifugal separator designed to remove impurities from mineral oils. The Alfa Laval solid bowl centrifuge is a manual clean separator. Therefore, the centrifuge must be stopped at regular intervals, and the solids retaining bowl must be manually opened to remove sediment. The feed pump of all Alfa Laval MAB separators is of the gear type. The gear pump is direct-driven by the worm wheel shaft.
The Alfa Laval MAB centrifuge is designed to clean lubricating oils, hydraulic oils, gear oils, quench oils, compressor oils, factory oils, marine diesel oils, mineral oils, and low-viscosity fuel oils by clarification or clarification purification.

Working Principles of the Alfa Laval MAB Centrifuge
What is a clarification separator?
Clarification (clarifier) is liquids/solids separation to separate particles, typically solids, from a liquid having a lower density than the particles.
An Alfa Laval MAB clarifier bowl will have one outlet. The clarified liquid (oil) moves towards the bowl center and discharges through the outlet. The solids move towards the bowl periphery and settle on the Alfa Laval solids retaining bowl wall.
What is a purification separator?
Purification (purifier) is liquid/liquid/solids separation with the intention of separating two intermixed and mutually insoluble liquid phases with different densities, the heavy liquid phase constituting the major part of the mixture. Solids having a higher density than liquids can be separated out simultaneously.
An Alfa Laval MAB purifier bowl will have two outlets. The purified oil leaves the separator through the oil outlet, and the water is separated out through the water outlet. The solids are forced towards the bowl periphery and settle on the Alfa Laval solids retaining bowl wall.
Commonly used in power stations and marine installations, the Alfa Laval MAB purifiers can remove particles of various sizes, from very large to extremely small, such as water droplets in fuel oils.
Factors Influencing Separation:
-
- Viscosity: Low viscosity facilitates separation. The viscosity can be reduced by heating.
- Density Difference (Specific Gravity Ratio): The greater the density difference between the phases of the process liquids, the easier the separation process. Raising the separating temperature can increase the difference.
- Separating Temperature: The temperature should be uniform throughout the separation process.
- Position of Interface: The interface between the liquid seal and the oil should be positioned as close as possible to the bowl periphery. The interface must not be located so far from the bowl center that the oil will pass the outer edge of the top disc, breaking the liquid seal and discharging with water—factors influencing the position of the interface: Oil Density, Size of Throughput, and Gravity Disc.
- Throughput: Excessive throughput may cause bad separating results. It is crucial to ensure the oil separator does not process more product than the maximum throughput capacity.
Centrifugal Separation vs. Gravity Separation
Centrifugal Separation
In an Alfa Laval MAB rotating disc stack centrifugal separator, the gravity is replaced by the centrifugal force, which can be thousands of times greater. The sedimentation and separation process is continuous and very fast. When liquid/solid particles in a liquid mixture (mineral oils, lubricating oils, hydraulic oils) are subjected to centrifugal force in a solids retaining bowl, it takes only a few seconds to achieve what takes many hours in a tank under the influence of gravity.
Gravity Separation
A turbid liquid in a stationary vessel will clear slowly as the heavy particles in the liquid mixture sink to the bottom under the influence of gravity. The lighter liquid phase will rise while the heavier phase sinks.
