FAQs
What makes Western Sealtech seals compliant with pharma regulations?
Western Sealtech inflatable seals meet FDA, USP Class VI, and GMP standards for pharmaceutical use, ensuring no contamination in sterile environments. Materials resist chemicals and withstand sterilization processes like autoclaving.
How do inflatable seals benefit cleanroom operations in pharma?
Inflatable seals provide contamination-proof sealing on irregular surfaces, ideal for cleanroom doors and hatches, maintaining ISO class standards during frequent openings. They inflate to seal gaps without compression wear, extending service life.
Are Western Sealtech diaphragms suitable for pharmaceutical valves?
Valve diaphragms from Western Sealtech offer superior flex life and sealing in corrosive slurries, common in pharma processing, reducing downtime and labor costs. Fabric-reinforced options handle high pressures in wier-type valves.
What materials do you use for pharma-grade seals?
Pharma seals use non-reinforced or fabric-reinforced elastomers like silicone, FKM, and EPDM, selected for biocompatibility and resistance to aggressive pharma chemicals. All undergo rigorous testing for purity and leachables
Can your seals handle sterilization in pharmaceutical production?
Yes, seals endure repeated autoclaving, gamma irradiation, and CIP/SIP cycles without degradation, critical for maintaining sterility in filling lines and isolators. Custom designs ensure zero particle generation.
How do Western Sealtech products prevent seal failures in pharma?
Inflatable designs avoid over-compression failures by inflating only when needed, with fabric reinforcement for extreme pressures in pharma equipment. Root cause analysis like 5-Whys informs durable solutions.
