Emissions Rules Push Duties Away From Mechanical Seals
A mechanical seal leaks by design, and fugitive emission rules in refining, chemicals, and pharmaceutical manufacturing have made that increasingly difficult to defend on hazardous or volatile duties. Sealless and magnetic drive designs remove the leak path entirely and grow at 8.6% against a market at 5.0% for that reason alone. They cost considerably more, run less efficiently on some duties, and cannot handle solids, so the conversion is regulatory rather than economic. Users who have made the switch rarely go back, because the compliance argument does not weaken. The compliance argument only tightens.
