• When people choose a mechanical seal, the choice
  of wear face material depends on factors such as
  the reliability and safety of the material, the
  complete lifecycle cost of the mechanical seal,
  and its usage and wear.
• Also, the selection depends on the sealed or
  pumped fluid How much is the resistance to
  erosion and corrosion. How much is the lubricity
  of the wear face material? Check the capability
  of producing a smooth and flat surface when
  lapped.
• Finally, the temperature, pump speed, and
  pressure are also important points of
  consideration. It is important to use
  high-quality material for longer service life.

HOW IS THE FACE MATERIAL CHOSEN?

• If you compare different face materials, then you
  will find that most materials show poor wear
  behavior when they are sliding in contact with
  another surface fabricated from the same
  material.
• It is the reason two dissimilar materials are
  used in a combination. While choosing the
  materials, one is always softer than the other.
• Only in extremely abrasive or corrosive
  environments, two hard materials are used. It is
  because the softer material will wear rapidly in
  this condition

• In extensively corrosive or abrasive
  environments, combination like Tungsten-Carbide
  and Silicon-Carbide are used.
• In applications where high pressure is used and
  the diameters are large, two faces fabricated are
  used so that the face deformation caused by the
  pressure force gets minimized.
• In such an arrangement, it is extremely important
  to keep the lubrication level high. In case of
  reduced or lost lubrication, the faces will get
  damaged or worn out faster.

TUNGSTEN AND SILICON CARBIDE- THE TWO MOST
PREFERRED FACE MATERIALS

• In widespread applications, Tungsten and Silicon
  Carbide are used popularly. The cost of these is
  higher than pure oxide ceramic and metallic type
  face materials. However, their higher wear
  resistance brings high levels of reliability and
  long service life.
• Also, these materials can work well in harsh
  lubricating environments, high speeds, and
  temperatures, and so on.
• In clean fluids, they are paired with softer
  materials such as carbon and graphite. In dirty
  fluids or fluids that contain abrasive particles,
  they are paired or matched against the surface of
  the same material.

• Looking at their properties and capabilities of
  giving a great performance in varied
  applications, these two materials are used
  commonly. The developments in products and
  industry standards in the past decade have shown
  the trend towards more use of silicon carbide.
• It is important to consult experts while picking
  the best combination of wear face materials.
