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.

Saving the day

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.

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.

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.

Clean sealing solution for demanding crystal production

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.

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.

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.
