ADVANTAGE ADVANTAGE RESULT

Wide originally designed time proven seal range for almost any pump atoil/gas gas exploration, transportation, oil refining division or petrochemicalplant. Deep knowledge of various equipment operational condition particu�larities.

Very good seals durability and standardization through all customer compa�ny divisions. Customer may implement "company through seal/pumpsmaintenance costs optimization program" with just one supplier.

Very competitive pricing if compared with prices of other world mechani�cal seal manufacturers.

Lower maintenance costs of pumps

Comprehensive SD and RDT tandem seal lines for both hot and lower tem�perature applications for oil refinery units starting from atmospheric andvacuum distillation to hydrocracker and ethylene units.

The SD and RDT seal lines have won Russian refinery engineers trust andnowadays about 75% of Russian major refinery critical process pumps areequipped with our seals while famous western manufacturers' share is lessthen 5%*.

Highly professional seal application engineers "trained" by pumps of morethen 25 Russian and CIS refineries and petrochemical plants. Our engineersare closely familiar not only with TREM Engineering seals but also with mostworld famous brands actual field operation particularities.

Most of our customers has chosen TREM Engineering engineers as mainconsultants, trouble shooters, and spare part supplier for ALL seals, includ�ing seals of famous western manufacturers.

Professional design engineers and flexible manufacturing are able to fitproven designs to any almost seal chamber of almost any pump.

Majority of CIS refineries have switched most of their Flowserve, Sulzer,Borg Warner, KSB and other western pumps to Trem Engineering seals.

*� The other 20% of critical pumps are equipped with seals of other local manufacturers.

• Due to the fact that many fluids at oil refineries and petrochemicalplants like hydrogen sulfide or MEA attack viton o_rings, SD seals arewidely used instead of o�ring seals.

• Metal bellows is highly resistant to cocking as compared to mechani�cal seals with o�rings.

• Metal bellows mechanical seals are balanced which reduces heat buildup.• Both stationary and rotary metal bellows are available.• Almost the only stationary bellows tandem seal on the market fitting

Advantages

• Welded metal bellows mechanical seals feature no rubber secondary

seals; all seal components are made of advanced thermally and chem�

ically resistant materials to substantially expand the range of applica�

tion temperatures and fluids.• The SO series mechanical seals are fitted with a throttle bushing as a

secondary seal; it can be used to seal inflammable fluids in compliancewith OST 26�06�2028�96.

• Being a single seal, the SO mechanical seal's support system is by farless complicated than that of a double mechanical seal (but before useplease check if you are allowed to use a single seal for the specificapplication).

• Compared to spring�loaded mechanical seals metal bellows seals aremore resistant to clogging and hang�up.

• Shaft sleeve is sealed by a gland tightened graphite gasket. This pro�vides for higher sealing safety especially with worn out orscratched/galled shafts.

• Metal bellows mechanical seals are balanced, so they have lower heatgeneration.

VOCs, crystallizing fluids, fluids with solids �

Advantages• RDT mechanical seal has a classical, proved by years, design that is

used for sealing light hydrocarbons such as liquefied hydrocarbongases, wide fraction of light hydrocarbons, petrol, reflux, etc. Suchapplications are challenging because due to increased pressures andslide speed seal rings tend to deform because of pressure and heatbuildup. This can lead to leaks and change of the low�boiling productphase (boiling or frosting). RDT�37 seal design provides optimumhydraulic balance and contact pressure thus contributing to stableoperation and long service life of seal rings.

• Seal rings are made from the proven high�performance materials �impregnated carbon graphite, silicon carbide, and tungsten carbide.

• Springs are made from Hastelloy® C to eliminate the possibility of cor�rosion cracking.

All of the above systems can be supplied with:

• level sensors/indicators • pressure switch • temperature sensor • safety valve • ball valves • and other C&I devices and valves
