Cartridge Seal Repair

Two 72mm Burgmann cartridge seals sent in to Robco of America’s Texas repair facility for failure analysis and overhaul under emergency basis. These seals came in from a chemical plant in Pasadena Texas. End user stated the seals operated for 6 months before failure. Upon inspection it was found that the Silicon Carbide rotary seats cracked close to the drive pin slots. Robco re-designed the drive pin slots to allow for an increased radial wall thickness around the slots to reduce the risk of future failure. New Silicon Carbide seats were produced in 4 working days.

In between time Robco machined new Carbon stationary seal faces that had a 20% wider lapped face. Reason for this modification was due to carrying out a stress analysis on the seal faces under operating conditions which found the Carbon faces were generating too much face load against the rotary Silicon carbide seal seats. The o’ring sealing surfaces in all the metal parts were polished to 32 RMS finish or better. Seals re-assembled and pressure tested to 60 PSIG for 20 minutes? no pressure drop.
