Upgrading oil-lubricated seals to seals with dry gas seal technology on centrifugal compressors offers attractive benefits for the operator: considerable cost savings, emission reduction and longer MTBM (Mean Time Between Maintenance). However, the technical realization is challenging and tricky.

Whether it’s for more volume, for more sheen, for dyed hair or for a well-groomed beard – the choice of shampoos seems practically endless nowadays. Only few people ever think about what happens before their favorite product is placed on the supermarket shelf. The production of hair wash products can be a great challenge for cosmetics companies. A variety of raw materials with different physical and chemical properties has to be processed. Canan Kozmetik, a sub-brand of L’Oréal based in Istanbul, faced a long period of constant downtimes and high maintenance costs due to seal failures. A solution was found by experts from EagleBurgmann in the form of cartridge seals with the innovative DiamondFace® Technology.

A boiler circulation pump in a power plant conveys very hot and pressurized water. The pump has no cooling jacket, which increases the risk of a thermosiphon effect.

In the highly sensitive production of vaccines, only a few barrier media and materials are approved for mechanical seals. If steam condensate is to lubricate silicon carbide sealing surfaces, premature wear is inevitable. How it actually does work is demonstrated by the case of an internationally operating pharmaceutical company.

Barrier fluid for seals is a risk factor in the pharmaceutical industry as it could contaminate the active ingredients produced. A globally active company is playing it safe and replacing liquid lubricated mechanical seals in paddle-wheel dryers with dry-running mechanical seals.

Sealing the agitator shaft of a mobile vessel is a very special task when dealing with a process in vaccine production. Liquid lubricated seals offer the best conditions for this application. However, the operation of dry contacting seals is more convenient and just as reliable as it is safe.

Special expansion joints from  EagleBurgmann compensate for these position changes and work reliably even under unfavorable conditions such as low temperatures, proximity to the sea and explosive environments. 

By means  of custom-made PLUG & RUN expansion joints  with a more wear-resistant material, EagleBurgmann was able to provide a solution which ideally fulfills the requirements with regard to wear while at the same time significantly reducing the changeover time.

The reliability of centrifugal compressors in gas grids are of the highest social and economic importance for network operators. Compressor performance and availability are closely related to the effectiveness of sophisticated compressor shaft sealing technology. Here, EagleBurgmann developed a new sealing concept which ensures better compressor availability: the coaxial separation seal CobaSeal.

EagleBurgmann supports shipbuilders, shipping companies and conversion companies globally with metal expansion joints for the flexible attachment of a scrubber within the exhaust gas system of a ship.

When the process medium in the production of metformin may not be contaminated with sealing medium under any circumstances, gas-lubricated seals for agitator shafts are the first choice. The Norwegian company Vistin Pharma took a daring step away from oil-lubricated to nitrogen overlayed seals.

A chemicals company in the Middle East uses the refrigerant R134A-Freon in the production of toluene diisocyanate (TDI). Shortly after the refrigeration plant is commissioned, the seal of a magnetic coupling pump fails. Quick help was called for.

In Drehrohröfen geht es heiß zu, sehr heiß sogar. Bei der Herstellung von Zement zum Beispiel misst das Thermometer mehr als 1.000 Grad Celsius. Dichtsysteme von EagleBurgmann, einem Unternehmen der Freudenberg Gruppe und EKK, leisten unter diesen „feurigen“ Hochtemperatur-Bedingungen nachhaltige Beiträge für Umweltschutz, Energieeffizienz und Prozesssicherheit.

Constantly changing operating conditions place extreme demands on pump seals in the production of antibiotic active ingredients. DiamondFace technology significantly extends the life of seals and enables the reduction of stock costs through rationalization.

A seal for a shaft diameter of 550 mm (21.65") – an absolutely thrilling dimension for EagleBurgmann. In close cooperation with the customer, we developed a durable and robust solution to help increase the overall efficiency of the pump in an Austrian reservoir power plant.

Seals are a risk factor in the production of liquid crystals. If there is even the slightest contamination of the liquid crystals, this will later affect the image quality of the display. Read on to see which sealing solution Merck KGaA uses in paddle dryers for the production of liquid crystals.

When media with hydrocarbons are pumped, seals in pumps can be exposed to high temperatures and wear caused by solids. The safety standards are high to protect the environment and personnel from leaking media. EagleBurgmann developed a robust solution with reliable safety properties for a refinery.
