Custom Rotary Joint with Metal Bellows Mechanical Seal
Metal bellows seal construction designed around your medium and duty
Overview
Metal bellows mechanical seals solve rotary-joint duty where ordinary packing or elastomer seals cannot follow — aggressive media, elevated temperature, or clean service that must stay free of leakage and contamination. The bellows acts as both secondary seal and flexible element, compensating for shaft runout and thermal movement without the wear path of a conventional pusher seal. Ruitus builds each unit to the customer's medium, temperature, pressure and interface geometry, selecting bellows alloy, face materials and housing to suit the process. Typical duties include chemical service, pharmaceutical equipment and other nonstandard rotating interfaces; share your medium and operating data and we will engineer the seal arrangement around them.
