RD Dry-Running Mechanical Seals were developed for sanitary applications to prohibit product contamination from barrier fluids. The line, which can be used for mixers, agitators and reactors, meets the ASME-BPE 2009 standards for cleanability. Capable of handling a 0.150-inch total run-out, these fully BPE-compliant seals feature a proprietary carbon blend and are supplied with or without a debris well. Internal metallic parts exposed to product have a 20 Ra finish with optional electro-polishing, and all components are either FDA-approved or USP Class VI-rated.
