The original

EagleBurgmann made a quantum leap in mechanicalseal technology when it introduced DiamondFacesin 2007. This new technology increases the service

lie o mechanical seals by a wide margin. Timebetween maintenance calls increases considerably,and lie cycle costs are much lower. DiamondFacestechnology oers signifcant value-add and boostsoverall system perormance in a whole range o oil& gas, refnery, chemical, slurry, pharmaceutical andwater supply applications.

Advanced coating technology forexceptional performance.

Raise your expectations. Performanceyou can rely on.

DiamondFaces advanced coating technology

What do ship owners, oil sand production companies, micro-electronics manufacturers, producers of ceramic sanitary ware

and chemical companies have in common?

They all rely on DiamondFaces to keep theirpumps, agitators and compressors running.

DiamondFaces on the high seas

The diesel engine on a large ocean-going vesseldoes not require high-grade uel. However, this placessignifcant demands on the uel supply systems. Thepumps and seals have to be designed to handle thechangeover rom heavy oil to low-sulphur diesel uel

while the ship is underway. Changeover takes place,or example, when the ship sails into waters which aresubject to stringent emission limits. EagleBurgmannhas provided mechanical seals with a DiamondFacescoating or installation on a cruise ship to supportchangeover between dierent types o uel.

Initial situation:

Frequent dry running o the mechanical sealswhich resulted in excessive stress at the sealaces and secondary seals due to uel gradevariations.

Corrective action:

Installation o an M7S mechanical seal withDiamondFacesTM coating

Result:

Signifcant improvement in emergency runningcharacteristics and drastic reduction in the tem-peratures which are generated during dry running.

The seal has been running ault-ree or more than10,000 hours.

DiamondFaces at an oil sand field

Production in an oil sand feld is a tough job, and thesystems are exposed to extreme conditions. With theSAGD method (Steam Assisted Gravity Drainage),oil is separated rom the sand using steam pressure.The handling systems have to cope with an extremely

abrasive mixture o oil, sand, water and steam. It ishardly surprising that the various components have tomeet very demanding specs. A Canadian producer hasdecided to deploy multi-phase pumps and mechanicalseals with DiamondFaces coatings.

Initial situation:

Repeated ailure o conventional mechanical sealsdue to insufcient lubrication and dry runningcaused by abrasive solids. API Plan 32 is not anoption in this application.

Corrective action:

Deployment o an HJ4S1 mechanical seal withDiamondFaces coating

Result:

Improved dry running characteristics and extensiono mechanical seal lie by a actor o more than 25.The mechanical seals have been running

ault-ree or more than 8,500 hours.

DiamondFaces in microelectronic

component production

Microelectronic component manuacturing is a highlysophisticated and complex process which is perormedin a cleanroom environment. A supply o ultra purewater is needed or some o the production steps.

Any contamination in the water would damage theexpensive, highly sensitive components. A French pro-ducer is one o the users who rely on EagleBurgmannmechanical seals with DiamondFaces coatings in theproduction process.

The unparalleled advantagesof DiamondFaces:


5/8

Initial situation:

A pump is located in close proximity to theprocess, and no contamination is allowed in theultra-pure water.

Solution:

Deployment o an HRC1 mechanical seal withDiamondFaces coating

Result:

DiamondFaces was easily able to exceed theapplication requirements because the coatingis virtually wear-ree. The application has beenrunning ault-ree or more than a year and a hal.

DiamondFaces in ceramic sanitary ware

production

Slurry casting is one o the standard ceramic ormingtechniques. The range o applications includesprototype production right through to production ocomplex parts and very large monoblocks. One eect

that is very noticeable in the pourable suspension isriction between the uid and the solid particles. Onemanuacturer o sanitary ceramic ware uses a mixingand dispersing machine which has a mechanical sealwith a DiamondFaces coating.

Initial situation:

The mixing and dispersing process causes a rapidtemperature rise at the seal aces, which results inadhesion o the suspension.

Solution:

Deployment o a Cartex-DN mechanical sealwith DiamondFaces coating

Result:

The low-riction DiamondFaces coating reducesthe temperature rise and avoids adhesion. Theapplication has been running ault-ree or morethan a year.

DiamondFaces in terephthalic acid production

Terephthalic acid is a basic chemical which is used inlarge quantities or the production o PET bottles/con-tainers and many types o polyester fber and otherengineering plastics. Acetic acid and other constituentsare mixed together during the production process. The

highly viscous mixture has poor lubrication propertiesand contains very hard particles. High-perormanceequipment is needed to handle this tough application.EagleBurgmann has installed mechanical seals withDiamondFaces coatings on an existing pump at aproduction site in Belgium.

Initial situation:

Due to the harsh properties o the media, conven-tional mechanical seals ailed repeatedly ater ashort period o time.

Corrective action:

Deployment o an M7 mechanical seal withDiamondFaces coating

Result:

The mechanical seal with DiamondFaces coatingruns without problems despite the harsh media.The seal has been running ault-ree or more than18 months.

All technical specifcations are based on extensive tests and our many years oexperience. The diversity o possible applications means, however, that they canserve only as guide values. We must be notifed o the exact conditions o applicationbeore we can provide any guarantee or a specifc case. Subject to change.

Leading-edge technology that solves your

problems

A microcrystalline diamond coating, which is in noway inerior to natural diamond, makes the crucial

dierence. DiamondFaces

is indispensable in applica-tions where seals have to withstand dry running, mixedriction and abrasive media. A diamond coating o8 m and more thick makes the seal aces extremelyhard and wear resistant. Other outstanding eaturesinclude excellent heat conductivity, maximum chemicalresistance and low riction. DiamondFaces deliversunparalleled perormance in a wide range o pump,agitator and compressor applications.

Would you like to save energy?

In todays world, resource conservation and businessdevelopment are not conicting goals. The willingnessto accept corporate social and ecological responsi-bility has now become a major competitive asset.Studies show that there are still huge opportunities toincrease the energy efciency o pumps, agitators and

compressors.

Mechanical seals with hard/hard material combina-tions and DiamondFaces coatings reduce riction byas much as a actor o 8 compared to conventionalseals. A reduction in riction cuts power consumptionand energy costs and makes the equipment moreefcient. The DiamondFaces coating also reducesthe amount o heat that is generated at the seal. Areduction in cooling requirements is a major advantageon double mechanical seals. The bottom line is thatDiamondFaces delivers a tangible reduction in energyconsumption and saves you money. You increase your

business efciency and meet your responsibilities tosociety.
