What does using Magnom Magnetic Filtration mean for me and my company!!!!

What does using Magnom Magnetic Filtration mean for me and my company!!!!

To truly understand the huge benefit offered by Magnom Technology I often ask engineers to just forget conventional sieve filtration for a moment, as I would not want it to corrupt the thought process and unique understanding offered by the Magnom proposition.

Essentially conventional filers are sieves, and are size discriminate!
But in our systems… size is not the threat, eg a 10 micron particle of say fibre offers little threat when compared to say a 10 micron particle of high carbon steel.

But a conventional filter treats these as the same, because it only addresses size and not threat!

Our history in the treatment of fluids here at Magnom teaches us something very import and very obvious in hind sight.

80% off all industrial and commercial products are manufactured from steel and iron. So it is no surprise that the majority of damaging contaminant trapped in products during manufacture are steel and iron!

Also during the break in (running in) process the contact surfaces that are breaking in against each other are typically high carbon steel!

Again during normal wear and tear during system use… high carbon steel particles are also present.
All of this is responsible for the start of the chain reaction of wear!

To quote Jim Fitch of Noria

“The worse things get…the faster things get worse”

Now! We do not have to be particularly well informed to conclude that these high carbon steel components that are ‘super hard, super sharp and microscopic in size’, are the greatest threat to any system (its essentially bits of the system killing the system),
These high carbon steel contaminants are also very small (typically sub 10 micron) this is because they are torn from hard surfaces, that don’t give them up easily. so they released from these surfaces as very small particles,
Having been torn off they are also angular and very sharp.

So it makes sense to treat these contaminants as the primary threat to our systems, be they industrial lube applications, or say hydraulic systems or indeed Formula one race systems.

What ever the system, Magnom offers a truly unique strategic answer to this 70 + year old problem. A problem that has been largely ignored while the only solution available was a sieve!

The Proposition…

Simply! remove the greatest threat, absolutely preferably before the systems pump!!!

(Before it is delivered to the rest of the system by the pump!!!)

Not partially as with conventional filtration (multi pass), on the return to the reservoir after the damage is done on its journey through the system!

In achieving this Magnom brings a host of health benefits to these systems as a whole!

Also with the Magnom product range you can strategically protect critical components and operations, and thus realise the benefits of effectively protecting your system or process.


It just makes complete sense !!!

HYDAC Magnetic Filtration test

Magnetic Filtration test

Magnom magnetic filtration technology

Magnom Corp, innovators in magnetic filtration/separation technology developed a special magnetic core to fit inside the popular Hydac LF 60, LF 110 & LF 240 filter housings.

It seemed only fit that this evolution in filtration technology be tested in house at Hydac.

It is clear from the Hydac test images below, that the Magnom magnetic core has proven hugely efficient.
Removing all of the micro-fine magnetic contaminant from the laboratory test fluids.

For a full size Hydac Test Image, pleas click this link:- 

You can see from the images, the progression of efficiency of the Magnom magnetic technology,

With the majority of the contaminant being removed from the fluids on entry to the magnetic core at the top of the stack of patented magnetic cores.
Contamination then reducing as the fluid passes further into the magnetic core.

It is also evident from the images supplied by Hydac, that the flow channels (fluid pathways) stay clean and clear of contaminant.and do not block or restrict fluid flow at any point, even when the magnetic core is totally full of contamination.

This also means that the contaminant remains in the traps created by the unique Magnom technology, out of the fluid flow.
Thus can not be washed off and re-introduced to the system (as with other magnetic devices),
This results in nil/negligible pressure differential across the patented magnetic core,
Winch means that Magnom technology can also be fitted to the suction/negative pressure side of pumps and systems, without fear of cavitation.

Put simply!

Magnom Technology is

‘the most significant Filtration development’

for over 70 years!

Magnetic filtration & the Prevention of failure of cement kiln drive transmissions

Magnetic Filtration

The build-up of micrometre-sized ferrous particles in lubricating fluid can result in the heavy wear and subsequent failure of cement kiln drive transmissions.

The application of magnetic filtration technology has proven to not only rectify this issue but can prevent build-up occurring, thereby increasing productivity and extending transmission life.

The build-up of ferrous contaminant in critical lubricating fluids can result
in heavy wear and the failure of cement kiln drive transmissions. The subsequent
blocking of oil/lubricant spray nozzles with the ferrous contaminant only makes the
attrition worse. The system can be starved of its lubricating oil supply, and/or suffer
from super-hard and sharp, micrometresized particles of steel passing between
critical working surfaces, in this case the gears.

No matter how good the lubricant, if it cannot be kept free from this severely
damaging contaminant, it is unable to do its job. The affected particles breech the
protective oil film and cause boundary layer rupture of the lubricant, resulting
in direct metal-to-metal contact. The subsequent system attrition can lead to
more oil changes being needed, as well as increased downtime and maintenance
costs, and eventually premature system failure.

Factoring in the cost of replacement parts (in this case the transmissions), as
well as engineering/maintenance time to replace the failed units, frequent oil
changes and premature preventative maintenance activities (in a vain attempt
to improve the cleanliness and condition of the system), the cost of rectifying this now
preventable issue is disproportionately huge. With the overall cost typically far
greater than that of the failed component, the ultimate cost lies in system downtime
and lost production.


The Magnom solution

To prevent this problem, UK-based
Magnom has developed a solution that
uses a specially-designed magnetic filter/trap.

The Magnom technology is highly efficient (single pass) down to submicrometre
levels, thus protecting any downstream components from the damaging steel contamination.

Importantly, the Magnom Magnetic Oil Module also retains the captured
contaminant in specially-designed traps to prevent the contaminant being washed off and reintroduced into the fluid flow.

Other benefits include:
• increased production availability, ie more up-time
• reduced maintenance costs and engineering resources
• lower component and transmission system replacement costs
• less lubricant usage
• increase in oil life
• pay-back immediate to within four weeks.


Benefits over conventional filter media:-

When the major source of damaging contamination in a system is ferrous
material, typically of a smaller size than the rating of a conventional filter, the
Magnom magnetic filter offers a number of advantages.

Conventional media filter needs replacing on a regular basis and restricts
the flow of the highly-viscous lubricating oils. Media filters have not only proven
incapable of solving the historic system problems of these transmissions, they also
risk the condition of a system further with restricted oil supply.
On the other hand, the Magnom solution holds up to 40x the contaminant
of conventional filters (size for size), and is non-restrictive and cleanable/re-usable.
Cement industry applications Magnom’s technology has been applied
to many customers within the cement industry, as well as in a myriad of
other market applications from power generation to Ferrari Formula One cars.
In terms of the cement industry, the filtration technology has been used
to clean highly-viscous lubricating fluids in cement kiln drive transmissions, to
protect highly-stressed transmissions running 24/7, and to extend
production life while reducing maintenance and repair costs.

Figures 1 and 2 depict

How the large build-ups of ferrous contaminant is
removed and held, from these critical systems at cement plants
in the Dominican Republic and the UK, respectively.

Figure 3 shows :-

The Magnom Max XL installed at a Carmeuse lime plant in the USA.

From reactive to maintenance mode

Typically when a Magnom unit is installed into a system experiencing issues, the
job in hand is to purge the system of large quantities of historic contaminant
circulating within it.
Once this historic threat is removed, the Magnom is effectively in ‘maintenance
mode’, ie removing contamination from the system as it is generated, thus preventing
build-up and ensuring the lubricating oil is able to do its job.
Fitted into a new system, the Magnom units are able to maintain oil cleanliness
and system health from the start, immediately delivering benefits for the customer.

Figure 4 shows :-

Oil analysis data provided for the Dominican Republic
plant by Exxon Mobil which carried out the installation and service of the Magnom™ In-Line-Process-Unit (IPU). The graph demonstrates the effectiveness of the
Magnom technology in cement drive transmissions and indeed, in transmissions generally.

Optimum oil performance

The removal of very small super-hard and sharp aggressive contaminants from oils
breaks the chain reaction of wear caused by their re-circulation within the system,
enabling the valuable oil in the system to perform at its optimum.
Extended availability of the transmissions to help maintain continuous
production is the main driving force behind producers choosing to adopt Magnom’s magnetic filtration.
Moreover, the technology is nowfitted as an OEM standard on cement
plant installations supplied by a leadingEuropean cement plant engineering

Magnom & Cubic3 / Reliability in Hydraulic systems ‘Magnetic Filtration Really Works !’

More positive news from the Cement and Concrete industry!


Long term Magnom customer Cubic3, ( are …

Manufacturers and suppliers of volumetric concrete mixers and KCP concrete pumps,

They have been fitting Magnom Products to their innovative equipment since their concrete mixer product launch in 2007.

This has provided a unique opportunity for long term evaluation of the reliability benefits provided by Magnom magnetic filtration,


Following the evaluation, even experienced Magnom engineers have been surprised by the level of system/component life extension seen in this application.


Jobey Marlowe (Technical Director of Magnom Corp) commented…

“We are familiar with the the long term benefits of using Magnom magnetic filtration that have been experienced by our customers, but we have not seen such a unique and long term account of system reliability previously, that provides such compelling evidence demonstrating :- that removal of micron size, super hard & super sharp ferrous contamination efficiently from hydraulic and lubrication systems can have such a long term and dramatic positive impact on system reliability”


Though we must also not forget the excellent design and engineering skills used in the Nurock product range.

Managing Director Graham Jones confirmed :-

Our product line has gained a growing reputation across the industry

for strength and reliability.

This in no small part .. thanks to Magnom Magnetic filtration products”.

Cubic3 & Nurock Technical Director Tony Jones… sums it up!

“In all of the years we have been producing our innovative systems, we have only seen three hydraulic pump or motor component failures and these were not even attributable to contamination, ‘this is unheard of in our industry”.

The Cubic3 team also commented :-

The fit and forget nature of the ‘Magnom PumpMate product’ (Suction strainer replacement), has also provided a reduction in filtration consumables along with a reduction in typical industry system & machine service intervals.

Which in turn with our enhanced reliability, provides increased machine production availability (and of course productivity) for the end user.

“Once we trialled Magnom products, and experienced the results, we could not conceive of building hydraulic and lube systems without installing these superior filtration products”.

“The cost V benefit has been a ‘no brainer’ for us!”

Could this be the cure for death of hard working Hydraulic and lube systems?

Magnom & Philadelphia Gear join forces to eliminate transmission / gearbox failures

Magnom MAX XL product line, now forms the backbone of Philadelphia Gear’s CORE system,


Which virtually eliminates ferrous metal contamination as a cause of lubrication related failures in gearboxes.

With more than a century of gear design and manufacturing behind us, Philadelphia Gear understands how lubricant contamination can negatively impact the operation of your critical rotating equipment. This is why we are proud to announce the arrival of a breakthrough technology that, quite simply, makes this problem a thing of the past.

The solution is CORE – ‘Continuous Oil Rescue Equipment’

We all face the same challenges:

How do we increase operating efficiency while eliminating unplanned downtime?

How do we extend the life of our equipment? How do we postpone the wear out phase of the infamous bathtub curve? Part of the answer to that question lies in the degree to which gearbox lubricants are kept free of ferrous metal contamination.

That’s where the Philadelphia Gear CORE System comes in.


Here’s why:

The smallest particle that can be seen by the human eye is 40 microns. But ferrous metal particles much smaller than this can cause extraordinary amounts of damage to rotating equipment over time. That is why upgrading your existing filtration system to include CORE is so important. CORE can remove particles as small as one micron or, put another way, particles as small as one millionth of a meter.

Machine casualties (often referred to as machine infant mortality) tend to occur during the break-in period of operation on the typical bathtub curve. After that the machine settles into its normal operation mode and tends to run well as long as it gets adequate levels of preventive maintenance. Then, at some point in time, the machine inevitably enters its wear out phase.

In many applications an interesting phenomenon has been taking place through all of this time. Ferrous metal wear particles have been floating through the lubrication system and taking a gradual toll on rotating elements within the gearbox. Bearings, gears, pinions, etc., are all susceptible to varying degrees of damage over the life-cycle of the equipment due to this type of ferrous metal contamination.

The CORE system is designed to trap these particles from the moment the filter is installed and oil begins to pass through it and, by doing so, CORE can literally move the wear out line further along the bathtub curve and extend the amount of time that the gearbox will run in normal operation.

The Evolution of Metal Filtration Technology


An engineer working on performance transmissions and engines for racing vehicles found that contamination of the lubricant was causing a reduction in performance and, eventually, catastrophic failure. Traditional barrier filtration techniques resulted in pressure drops that inhibited the fluid flow, which made them unusable in high-speed or critical applications. It is an age-old problem that defines tribology, the science of the mechanisms of friction, lubrication, and wear of interacting surfaces that are in relative motion.

The engineer wasn’t satisfied with a traditional approach to solving this problem. After all, the problem had been around as long as gearboxes themselves and was considered an inevitable maintenance issue. Then, after years of experimentation, a breakthrough occurred.

By using a system comprised of a series of annular magnets shrouded by steel plates, it was discovered that oil would pass through the flow channels at the magnets’ outer edge, while harmful contaminants were simultaneously stripped out and deposited in the collection zones that resulted from the strong magnetic fields surrounding the oil flow.

This technological breakthrough has been proven season after season within the demanding Formula One racing environment and is now routinely specified on new racecar designs. And now, Philadelphia Gear is bringing its own proprietary design of this patented technology to the industrial marketplace.

Critical equipment is critical equipment and it doesn’t have to be roaring around a track at 200 MPH to earn that designation. Whether it’s a coal crushing application in a power plant, a conveyor drive in an automotive plant or a pump drive at a remote pipeline installation, CORE technology gives you the peace of mind that comes with knowing your lubricant is being kept as clean as possible.

How The Technology Works


At the center of the Continuous Oil Rescue Equipment is a series of annular magnets with larger steel plates shrouding them. These plates, which have a series of flow channels running through them, become fully magnetized. When the oil is filtered through these plates, it is subjected to a high magnetic flux gradient, caused by the focusing of the magnetic field at the tips of the plates. The result is that any contaminant is drawn into collection areas (out of the oil flow) between the plates.

The adjacent diagram shows how oil (blue arrows) passes through the wide flow channels at the edges of the steel plates and exactly how contaminants are removed by the magnetic field (red arrows) for storage in the collection zones. It’s important to note that this occurs with virtually no pressure drop even when the CORE is fully loaded with contaminant.

The reason the filter does not create a pressure drop is because CORE was designed such that the flow channels sum to a greater flow volume than that of the inlet pipe. Therefore, as the contaminant is drawn into the collection zones by more efficiently focusing the magnetic flux, refraction of the oil compacts the contaminant and ensures that it is held out of the flow paths. This results in a negligible pressure drop, while at the same time, also helps prevent “wash off” since – unlike magnetic sump plugs, for example – the contaminant is isolated and can not wash back into the oil.

Benefits of Near Zero Pressure Drop

  • For the first time fine filtration can occur on the suction side of the pump
  • CORE is more accessible for condition monitoring of the power transmission system
  • Pressure drop is avoided even when the filter element is full
  • Oil viscosity does not effect the filter’s performance.
  • Because the magnetic filter element has an area equal to 110% of the inlet, there is zero risk of oil pressure drop inside the gearbox upon installation.

Additionally, because CORE holds significantly more contaminant than a conventional filter – as much as 2 lbs. of ferrous metal contaminant between cleanings – it can operate for long periods without service. When service is needed the unit can be easily cleaned and immediately put back to work.

Summary of Metal Filtration Benefits

  • Reduced failure rate of power transmission equipment
  • Lubricant life extended as wear particles are removed
  • Reduction or elimination of spare filter inventory
  • Cleaner oil means cooler oil and lower operating temperatures
  • Equipment life extended as wear particles are removed
  • No significant pressure drop as lubricant is pumped through filter
  • Filters can be cleaned and immediately put back in service
  • No pressure drop means filters can be installed upstream of the pump
  • Protection of the pump with minimal risk of cavitation
  • Cost effective insurance to maximize equipment available time

Most Frequently Asked Questions About CORE

How Long Will A CORE Unit Last?

The magnets inside your CORE unit have a half-life of 50 years. The housing is made of high grade aluminum so, for all intents and purposes, each CORE unit is designed to outlive virtually any machine.

What Size Lube Lines Do I Need to Install A CORE System?

There are two versions of CORE. The larger unit is designed for lube pipes that range between 1.25″ – 2.0″ in diameter, and the smaller unit is designed for piping between .5″ – 1.25″ in diameter.

How Do I Clean The CORE After Installation?

Each unit comes with a set of instructions on cleaning, but in general the most effective way is to disassemble the unit and then use an 80 PSI air line and blow off gun/nozzle to clean the magnets and debris collection zones. In this manner the CORE can be efficiently and effectively cleaned and readied for reinstallation and reuse.

How Will I Know When the CORE is Full?

Disconnect the CORE unit from the lube system and remove the flanged or threaded cover. We recommend this be done annually during the unit’s routine cleaning cycle. Those customers with highly contaminated lube systems may choose to do this more frequently.

How Much Debris Does A CORE Unit Hold?

The large unit holds up to two pounds of debris and the small unit holds nearly one pound of debris.

What if I Don’t Want to Shutdown my Process to Perform Maintenance on CORE?

CORE can be configured in a duplex arrangement that makes unit shutdown for maintenance unnecessary. The units can also be piped in a “kidney loop” configuration to allow them to be valved off for cleaning if a duplex arrangement is not feasible for whatever reason.

What is the Physical Size of A CORE Unit?

The CORE is designed to be compact. The large unit is 8” in diameter and 9.5” long at widest and longest points, respectively. The smaller unit is 5” in diameter and 6.5” long.

How Much Does A CORE Unit Weigh?

The large unit weighs approximately 10 lbs. and the smaller unit weighs approximately 5 lbs.

What Does the CORE System Cost?

There are several variables that impact the cost of the CORE system including, how many units are being sold, are they in a single or duplex configuration and, most importantly, which size CORE is necessary to fit your application. But even at the one-off price of $1995 for the large unit and $1495 for the small unit, we can say that relative to the costs of downtime, the cost of CORE is negligible and has been priced to be a “no-brainer” addition to even the tightest maintenance budgets.

REXROTH & Magnom prove the value of Pre Pump, Suction filtration

Variable Piston Pumps ‘VP Pumps’ along with more conventional pumps, have to ingest contaminants from the reserviour that pass return line filtration.
Historic use of mesh/suction filters has been proven to cause cavitation and premature pump failure.
Thus these typical suction strainers have to be made of very course mesh, rendering them unable to stop the damaging contaminants from entering the pumps and system.

Such is the problem with the historic use of these strainers that, this has seen Bosch Rexroth refuse warranties on systems using mesh suction filters.

But innovation has moved on, in conjunction with Magnom Corp, rexroth set out to test and understand the value of Magnom’s Magnetic Suction separator “The PumpMate”.

It will not be a surprise to hear that removal of ‘super hard’, ‘super sharp’ micronic particulate from systems can have a huge benefit for the systems.

Aggressive contaminants removed Pre-Pump

The Magnom PumpMate acheives this function:-

1, Pre Pump protection
2, To sub micron levels
3, Is non restrictive (no cavitation issues)
4, Is potentially fit for life (massive capacity so, no servicing required)
5, Flows as much fluid when full of contaminant, as when empty.
6, Low cost
7, No bigger than a suction strainer.

In testing carried out by REXROTH, the system fitted with the PumpMate hit “NAS 3” cleanliness,

The unit even removed some non ferrous contaminants (See analysis below).
So impressed were REXROTH, they committed to feature the PumpMate product on their stand at the Hanover Fair, in Germany.
PumpMate was also awarded the coverted REXROTH ‘AB’ standard for best practice product.

We know of no other filtration/separator that can be fitted to the suction side of a Pump without risk of invalidating warranty

REXROTH At Hanover, & the REXROTH Prototype PumpMate




Magnom & TEREX improving the performance of critical hydraulic and lubrication systems.

Following exhaustive testing, both in house and on live vehicle trials

TEREX have now adopted Magnom PumpMate products, as standard
Equipment on hydraulic systems.

This follows exhaustive evaluation of PumpMate product, fitted to the
suction ports of hydraulic pumps on their range of Dump Trucks.

Magnom PumpMate technology protects the pump and the entire system,
from recirculating wear materials, generated in the harsh conditions
in which the TEREX trucks are employed.

The PumpMate product can be a fit for life proposition, (fit and forget),
And can easily last the life of hydraulic systems, without requiring service.
(Note! system dependant).

Removal of ‘Super hard’, ‘Super sharp’ micronic contaminants from
these systems, (that are allowed to recirculate through conventional
Filtration), can have a massive positive impact on system life and health.

Thus increasing machine availability, increasing production, while reducing
maintenance cost.

A massive benefit to the machine/end user.

Magnom products are being widely used/specified by a wide range
of off highway OEM companies globally.
As well as many after market heavy equipment users

Noria, and The Rationale For Using Magnetic Particle Collectors

By Jim Fitch, Noria Corporation,

Let’s face it: Machines in industry are largely made of iron and steel. Ferrous metals both encase these machines and bear the brunt of most friction, wear and corrosion. Often, the most critical machine components, parts and surfaces are those that possess the greatest intrinsic strength and wear resistance. In more than 90 percent of the cases, these mission-critical components have iron-based metallurgy. Common examples include cams/followers, gear teeth, shafts/journals, rolling elements and raceways of bearings, pistons and cylinders, mechanical couplings, chain drives, screw drives, and rotors.

As machines age and wear, metal is lost to the lubricating oil or grease. The rate of wear is directly proportional to the growing ferrous particle population in our lubricants and filters. These mobilized wear particles pose even greater risk in causing collateral damage elsewhere in the machine. Common examples include particle-induced abrasion, surface fatigue and motion impediment of sliding and rolling parts. So, too, it is well known that metallic particles are a principal root cause of lubricant aging and base oil oxidation.

With rare exception, ferrous particles caused by mechanical wear are also ferromagnetic, meaning these particles have inherent magnetic susceptibility. In some cases, this attribute is a drawback (e.g. the potential interference of solenoid actuators), but in most cases, it presents a distinct opportunity for efficient wear particle removal and detection. This is the central theme of my column in this issue.

Magnetic Susceptibility as a Contamination Control and Condition Monitoring Strategy
Particles will enter lubricants either from internal or environmental sources. Hence, the first goal of any contamination control program is to create a barrier to contaminant entry (called contaminant exclusion) wherever possible. Consider this: For every particle that is not released into the oil (or is rapidly removed), there may be five or 10 more that are not being generated, or allowed to be ingested, as a direct result. The concept of particles making or abetting the ingression of more particles is well known. When effective, this presents an important machine reliability opportunity to mitigate the destructive and self-propagating consequences of contamination.

There are numerous well-engineered magnet-based particle-removal devices on the market. Many of these products were discussed in an article authored by my son J. Bennett Fitch in the September 2005 issue of Machinery Lubrication (visit to retrieve this article). Magnetic filters and separators have the ability to selectively remove ferrous particles at various degrees of efficiency based on such factors as particle size, metallurgical composition, flow rate, viscosity and magnetic strength (flux density).

When the magnetic separation and detection technology is properly selected and positioned in the machine application, the benefits can be extensive (see figure). These include:

Enhanced lubricant oxidation stability: Many lubricants are highly stressed due to exposures from pressurized oxygen, suspended moisture and heat. Ferrous particles are known oxidation catalysts which can figuratively “fan the fire”. Their removal from the oil does just the opposite, resulting in an oxidation suppressant. In certain cases, this can permit less expensive lubricants (vs. synthetics, for instance) to be used in applications to achieve extended service life (longer oil drains).

Improved filter performance: When magnetic separators are used upstream of filters, there is the possibility of the system filter benefiting from longer service life and higher particle capture efficiency. This can result in reduced cost of filtration (parts and labor) and enhanced contamination control.

Particle removal in unfiltered fluids: Many machinery lube oils cannot be filtered for a variety of reasons. These include lubed-for-life applications and non-circulating systems (those without a pump and forced oil flow). Examples include splash-fed gearing, bath-lubricated bearings and oil ring applications. In other cases, the type of lubricant is not particularly filterable, such as very high viscosity oils and oils that contain solid or semi-solid additives. While these fluids cannot be filtered, they can usually benefit from magnetic separators as a practical alternative.

Controlling particles during filter bypass: Many filters operate in partial or full bypass for extended periods of time. There is a range of reasons why this occurs, including cold-start conditions, premature filter plugging and load-induced flow surges from hydraulic actuators. There are numerous oil filter applications where no filter bypass indicator or gauge is in use to provide an alarm. For instance, the vast majority of oil filters on diesel, gasoline and natural gas engines have no bypass indicator. Yet, in these same applications, there are numerous causes of premature filter blockage (coolant leak, for instance). In such cases, magnetic particle separators can provide some enhanced particle removal during filter bypass.

Wear particle detection and identification: Sadly, most people are oblivious to the condition monitoring potential of magnetic particle separators and collectors. Oil analysts are well aware of the limitations of relying entirely on oil samples to flag incipient and impending machine failure. Systems that utilize low-micron full-flow filters can strip out more than 99 percent of the wear debris generated by bearings and gears, for instance. The remaining wear particles are often very small and low in concentration, not representing the true debris-generating conditions of the machine. Machines that have high fluid volume or high fluid turnover (i.e., the number of times per hour the fluid passes through the filter) can represent real challenges for wear debris detection and analysis with conventional oil analysis from samples. Conversely, magnetic particle collection devices placed upstream of filters can enable quick inspection and retrieval of virgin particles (freshly formed and not reworked by the machine) for analysis.

One Part of an Overall Solution
By itself, magnetic devices are not a cure-all for contamination control problems and fault detection needs. However, when used in combination with other prudent maintenance practices and technologies, an overall enhanced level of machine reliability at a lower cost can be achieved. Years of experience from the user community have provided ample evidence and motivation to deploy magnetic separators and detectors wherever possible.
