Type 32 D vessel seals are outside-mounted, balanced single seals with self-lubricating seal faces. Neither external cooling, lubrication equipment nor a supply system is required. The design and material selection meets the needs of the pharmaceutical and chemical processing industries. The seals are excellent for low-duty mixing applications and operation in vacuum conditions. The seal can be supplied in component form consisting of spring-loaded face, driver retainer and mating ring, or pre-assembled on a flange. The flange version can be equipped with a debris well, enabling it to capture face wear particles, preventing the contamination of process fluid. Standard flange designs are available with dimensions to DIN 28138 Parts 1 and 3. Customized flanges available on request.
