High quality factory PTFE Graphite Braided Packing for Lahore Factories

It is a braided packing made of PTFE yarn containing graphite. It is recommended for shafts for almost all chemicals. Stability and long service lift are achieved by low friction coefficient. It has great tear strength and high thermal conductivity. This self lubrication packing does not score the shaft and minimizes sleeve rep, acement cost. It can be used to seal alkalis, solvents, water, steam, acids except strong oxidizing acids( aqua regia, fuming nitric acid, fuming nitric acid, fuming sulfuric acid,etc.) for centrifugal pumps, autoclaes, agitators mixers, etc.

Technical Data Sheet

It can be used to seal alkalis, solvents, water, steam, for centrifugal pumps, autoclaves, agitators, mixers, etc.

NOTE: rear shaft seal is not covered in this video – this information can be found online. If you have a deep groove worn into the shaft from this seal, you may have to install the new one in a slightly different position to contact an undamaged part of the shaft to prevent leakage from the backside of the pump.

The MB re-seal kit only includes the front cover o-ring and rear shaft seal – if your pump continues to leak from the front cover after replacement of this while operating, the internal O-rings will be leaking. With time and heat they have all gone hard and brittle now anyway.The internal o-rings have to be sourced from the aftermarket. They are not available as a spare part from MB. They want the whole pump replaced in such case.

Also note, i suggest using something like silcon o-ring grease to allow easy installation of the internal o-rings. Oil on its own may allow the rings to bind and be cut, chipped or shaved, resulting in enormous leaks.
