Pharmaceutical manufacturing runs on a standard most other industries don’t have to meet: every wetted surface a process fluid touches has to be contamination-free, cleanable, and validated. Mechanical seals on reactors, mixers, and transfer pumps sit right at that boundary — they’re one of the few rotating components in direct or near-direct contact with the product, which means a poorly specified seal isn’t just a maintenance risk, it’s a product quality and regulatory risk.
At Leak-Pack Engineering, we design and manufacture mechanical seals for pharmaceutical process equipment, built to hygienic design standards and manufactured from materials that support clean-in-place (CIP) and steam-in-place (SIP) validation. Whether you’re sealing a bioreactor, a sterile mixing vessel, or a solvent transfer pump in an API manufacturing line, our engineering team works from your process and validation requirements — in line with FDA Current Good Manufacturing Practice (CGMP) regulations — to recommend the right seal design, materials, and documentation.
