Maximum robustness for centrifugal compressors

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.

Refinery pump - maximum leak tightness

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.

Mixing without risk

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.

Rotates silently and unobtrusively

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.

Service life of three years and more

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.

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.

Does not blow off steam

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.
