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.


Reliable compensation in exhaust gas system

An FSPO unit is equipped with power generation and waste heat recovery systems from different manufacturers. The correspondingly disparate expansion joints failed after a short time. EagleBurgmann supplied a low-maintenance solution that is now part of the standardized equipment of other FPSO units.


Robust component in ensuring sterile vaccine production

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.


RoTechBooster for pipeline compressors

With a strategic alliance between EagleBurgmann and the Alliance Pipeline, which leads from British Columbia and North Dakota to Chicago, best practice methods for maintenance and availability were to be implemented. EagleBurgmann PDGS seals are installed in the pipeline's compressor stations.

EagleBurgmann convinced the persons responsible for the liquor line in a pulp mill to equip the shaft of the pressure disk filter with a practical and reliable mechanical seal, thereby increasing the MTBR to an extraordinarily long period of three years.


Sealing of polymer dispersion (Latex)

The handling of latex is a major engineering challenge for the mechanical seals that are used on pumps and reactors. One of the German EagleBurgmann service centers collaborates with the operator of the Marl Chemical Park, and has been supplying it with individual sealing solutions for many years.


Sealing solutions for applications compliant to TA-Luft and ATEX

TA-Luft and ATEX requirements make it necessary for operators to replace all seals used that are not conform to the standards. At Chema Prozess- and Systemtechnik in Germany, EagleBurgmann equipped steel distillation vessels with double mechanical seals in cartridge design that meet the needed legislations.


Seals the superlatives of shafts

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.


Secure and reliable, even where lubrication is poor

Poor lubrication and sliding faces in hard-hard pairing - there are better conditions for the perfect functioning of a seal. EagleBurgmann nevertheless reliably seals the agitator of a fermenter for the production of biocultures for the long term.
