3.00″ Sharpe double mixer seal. Carbon vs Silicon (outer end). Carbon vs Tungsten (product end). Kairez o’rings for high temps.
Back to back T8 Carbon faced seals on the rotary seal sleeve, surfaces covered in oil & Carbon residue.
Due to the fact a new seal sleeve is required. We can look at drilling and tapping an extra hole to utilize a setscrew. The seal only has (2) setscrews to make it rotate with the shaft, we think the seal should have at least (3) setscrews. Also, they should have Loctite applied when the seal is re-installed on the tank.
Rotary seal sleeve has been “slipping” on rotary shaft. I.D. bore is worn and non repairable. The bottom plate, bearing sleeve and the main seal housing require cleanup, polish on o’ring sealing surfaces and re-machine as required to remove indents & scratches.
