What Is an Alfa Laval MMB Separator?

The MMB is a high-speed disc-stack centrifugal separator with a solids-retaining bowl. It is designed for continuous oil processing between manual bowl-cleaning intervals.

An MMB separation system generally includes:

• An MMB separator

• Connections and valve assembly

Depending on the required installation, optional equipment may include:

• An independent oil-feed pump

• An oil-heating system

• Electrical controls

• Monitoring and protective equipment

• Additional system accessories

The exact scope must be confirmed for the selected model and application.

MMB 304 and MMB 305

The MMB range is principally associated with two models:

Alfa Laval MMB 304

MMB 304 is a compact solids-retaining separator used for compatible mineral-oil cleaning duties. It can be supplied as part of an oil-cleaning system selected for the required capacity and oil condition.

Alfa Laval MMB 305

MMB 305 is intended for higher-capacity oil-cleaning requirements within the MMB range. Its suitability depends on oil properties, contamination, temperature and the required treatment result.

Model selection should not be based only on the desired flow rate. The oil viscosity, density, temperature, water content and solids loading must also be considered.

How Does an MMB Disc-Stack Separator Work?

The operating principle involves the following stages:

1. Contaminated oil is transferred towards the separator.

2. Where required, the oil is heated to an appropriate temperature.

3. The oil enters the rapidly rotating separator bowl.

4. A stack of conical discs divides the oil into thin layers.

5. Centrifugal force moves denser solids and water towards the outside of the bowl.

6. Lighter cleaned oil moves towards the centre and leaves continuously.

7. Separated solids accumulate inside the bowl.

8. The separator must be stopped periodically so that retained solids can be removed.

The disc stack increases the effective separation area and shortens the distance travelled by contaminants during separation.

Clarification and Purification

MMB Clarifier Operation

In clarification duty, the separator primarily removes suspended solid particles from oil. The cleaned oil is discharged continuously, while separated solids remain in the bowl.

Clarification may be appropriate where solid contamination is the main concern and significant water separation is not required.

MMB Purifier Operation

With the applicable configuration, purification separates:

• Cleaned oil

• Separable free water

• Retained solids

Correct purifier operation requires suitable oil density, temperature, flow and internal setup.

The MMB should not be described as removing all water. Dissolved water and stable emulsions may not separate in the same way as free water.

MMB Oil Separator Applications

The MMB may be evaluated for cleaning compatible:

• Lubricating oil

• Hydraulic oil

• Turbine oil

• Compressor oil

• Gear oil

• Engine oil

• Marine diesel oil

• Selected fuel oils

• Running-in oil

• Other appropriate mineral oils

Oil compatibility and the required outlet quality must be confirmed for each application.

Lubricating-Oil Cleaning

Lubricating oil can become contaminated with wear particles, rust, dust and water during machinery operation.

MMB centrifugal separation may support oil maintenance for:

• Diesel engines

• Turbines

• Industrial gearboxes

• Compressors

• Hydraulic systems

• Power-generation equipment

• Marine machinery

• Manufacturing equipment

Centrifugal separation can remove separable contaminants, but it cannot reverse oxidation, additive depletion or chemical degradation of the oil.

Fuel-Oil Purification

Fuel can acquire water and solid contaminants during storage, transportation and transfer.

An appropriately configured MMB purifier may help remove:

• Free water

• Rust particles

• Sediment

• Dust

• Other separable solids

The fuel type, density, viscosity, required flow and operating temperature must be reviewed. Highly viscous oils may require controlled heating to support separation.

Hydraulic-Oil Cleaning

Hydraulic oils require contamination control to protect pumps, valves and actuators. MMB treatment may be considered for removing separable free water and suspended solids.

Where a very specific particle-cleanliness class is required, filtration may also be necessary. Centrifugal separation and filtration perform different but potentially complementary functions.

Turbine and Compressor Oil Cleaning

Water and particulate contamination can affect the condition of turbine and compressor lubrication systems.

An MMB separator may support continuous or side-stream oil-cleaning arrangements, subject to:

• Oil grade

• System capacity

• Contaminant type

• Water content

• Oil temperature

• Required cleanliness

• Operating schedule

Equipment-manufacturer oil requirements must be respected.

Advantages of an MMB Oil-Cleaning System

Depending on the application, potential advantages include:

• Continuous oil processing between cleaning intervals

• Removal of separable free water

• Removal of suspended solids

• Compact disc-stack separation

• Reduced reliance on disposable filter elements

• Optional packaged-system components

• Installation flexibility

• Treatment of different compatible mineral oils

• Support for cleaner oil-management practices

Actual performance depends on feed properties, correct operation and maintenance.

Why Oil Temperature Matters

Oil viscosity strongly influences centrifugal separation. Contaminants generally move less easily through highly viscous oil.

Controlled heating may reduce viscosity and improve separation, but the temperature must be selected according to:

• Oil grade

• Flash point

• Manufacturer recommendations

• Separator limitations

• Additive stability

• Installation-safety requirements

Do not overheat the oil solely to increase separator capacity.

Factors Affecting MMB Performance

Feed Rate

Excessive flow reduces the time available for contaminants to separate.

Oil Viscosity

High viscosity can reduce the movement of water droplets and particles through the oil.

Oil Density

Density influences the separation of oil and water in purifier operation.

Water Characteristics

Free water is generally easier to separate than dissolved water or a stable emulsion.

Solids Loading

Higher solids loading fills the retaining space faster and shortens the required bowl-cleaning interval.

Particle Properties

Particle size, shape and density affect how readily solids separate.

Bowl Condition

An incorrectly assembled or dirty bowl can affect both performance and operating safety.

MMB Versus MAB Separator

Both MAB and MMB are solids-retaining disc-stack separators associated with mineral-oil cleaning.

The MMB page should concentrate on:

• MMB 304 and MMB 305

• Packaged oil-cleaning arrangements

• Connections and valve assemblies

• Optional pump, heating and control equipment

• Marine, power-station and industrial oil-cleaning systems

The MAB page should remain focused on the broader MAB solids-retaining purifier and clarifier range.

The appropriate separator should be selected from the current model availability and application data, not merely from similarities between the two ranges.

MMB Versus MOPX Separator

MMB uses a solids-retaining bowl that requires the separator to be stopped and opened for accumulated solids to be removed.

MOPX belongs to a different separator design family with different operating and solids-handling arrangements.

MMB may be appropriate when:

• Solids loading is manageable

• Manual bowl-cleaning intervals are acceptable

• A compact system is required

• The capacity matches MMB 304 or MMB 305

Another separator may be preferable for applications involving heavy solids loading or longer uninterrupted operation.

MMB Separator Versus Oil Filtration

An oil filter captures particles using filter media. An MMB separator uses centrifugal force to separate contaminants based on density and separation behaviour.

MMB can remove separable water and solids without depending entirely on filter-media pore size. Filtration may provide finer particle control.

The two technologies may be used together when required by the oil system.
