high quality silicon carbide mechanical seal problems

Plant Engineering | Mechanical seal rings

Low viscosity liquids are difficult for mechanical seals because the hydrodynamic film that they create between the two rubbing seal faces is extremely thin. The M-444 is able to counteract this with a self-polishing feature as well as the high dimensional stability of both solid silicon carbide and antimony impregnated carbon-graphite that enables these two materials to run in the required

Back To Basics: Mechanical Seals for Water and …

Because mechanical shaft seal failures are the nuer one cause of pump downtime, the writer decided to dedie this column to mechanical seal basics. Years ago, most pump shafts were sealed using rings of soft packing, compressed by a packing gland, but this type of shaft seal required a fair amount of leakage just to lubrie the packing and keep it cool.

Why Mechanical Seals Fail?

2. Use low-friction face materials. Carbon vs silicon carbide is the best choice. 3. Use a clean liquid flush or product recirculation to carry away heat. Mechanical Seal materials attacked: When the correct materials are not selected, 1. The o-rings may 3.

The Trouble With Silicon Carbide | Pumps & Systems

Traditionally, pump manufacturers used SiC (silicon carbide) for bushings and bearings in these pumps because of its high hardness and ability to withstand abrasive wear in solid media. Since the early 1980s, OEM pump manufacturers have been using sintered SiC bearings for the stationary and rotating components of tubular casing pumps.
