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.
