Glass Lined Double Reactor Seal Repair

Seal Repair

95mm glass lined double reactor seal sent in for repair from chemical plant in Texas. Unit had Silicon Carbide vs Silicon Carbide (inboard & outboard), Teflon encapsulated o’rings product side & Kalrez / Viton outboard. The product end rotary Silicon face was broken & jammed in the rotary housing. Upon inspection we found the drive lugs in the rotary metal holder were sheared off. A new Silicon face + 316 stainless holder required. The glass lined flange was cleaned up & painted. All metal parts cleaned, polished & re-machined as required. Mechanical Seal unit was reassembled & pressure tested to 100 psig. This job was turned around in 1 week.
