Type 5280, 5281, 5282
The first choice for ultra-clean pharmaceutical and biotech applications, these seals meet Qualified Hygienic Design (QHD) requirements to enable the cleaning and sterilization of the productwetted parts with the seal in place (CIP, SIP). Different versions of Type 5280 Series are suitable for different vessel materials: Type 5280 for steel, Type 5281 for glass-lined and Type 5282 for special alloy vessels. Each type is available as liquid-lubricated, contacting dry-running or noncontacting gas-lubricated versions for high-purity applications. The special inboard seal design allows the application on top, side and bottom entry vessels. All versions are suitable for operation in potentially explosive atmospheres (ATEX cat. 1–3).
