Mechanical Seals for Pharmaceutical Industry
Sterility Requirements
Pharmaceutical mechanical seals are essential for maintaining sterility in pharmaceutical processes where they are used to seal pumps, valves and other equipment handling sterile fluids. Tight seals prevent contamination of products with airborne microbes that could render drugs non-sterile.

Aseptic Processing
Seals enable aseptic processing where equipment is sanitized instead of undergoing sterilization. They form barriers isolating sterile zones to facilitate filling of vials under aseptic conditions without risk of microbe ingress. This is important for drugs like vaccines filled in open vessels.

Containment of Toxic Substances
When handling hazardous drugs like chemotherapy medications, mechanical seals contain toxic and carcinogenic substances preventing worker exposure. They seal bioreactors, centrifuges and other equipment producing or isolating dangerous compounds.
