Technical Data Sheet

 Application Area

It affords longer service life under severe conditions which conventional asbestos packing can bot provide satisfaction, such as mine, tin ore, paper pulp, feed water pump of power stations, 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.
