Top 5 Things Mechanical Seal Users Need To Know

Essential point about Mechanical Seal Users

• Though the mechanical seals are being used in
  centrifugal pumps for more than eight decades
  now, they are still a lesser known element of
  the pump. Moreover, there has been almost
  negligible change happened in their design.
• Despite the fact that seals play a crucial role
  in the proper functioning of the pump, several
  aspects of mechanical seals are unknown to the
  people.
• This blog explains top five things that everyone
  who uses mechanical seals should know. These tips
  will enhance the knowledge of users and help in
  getting the best performance

MECHANICAL SEALS ARE PRONE TO WEAR AND TEAR

• A hydrodynamic lubricating film separates the two
  sealing faces of the seal. It provides the
  leakage path.
• In principle, the seal should last forever.
  However, we all know that it is impossible.
• When the film collapses, and the faces of the
  seal come into contact during the stopping and
  starting condition, wear and tear occur.
• Sometimes, the wear gets accelerated due to
  abrasives get trapped between the faces.
• Process upset conditions also cause wear and
  tear.
• All these aspects must be known to a mechanical
  seal user.

2. MECHANICAL SEALS REQUIRE LUBRICATION

• The design of a mechanical seal is quite simple.
  It has two parallel faces that slide past each
  other. A hydrodynamic film keeps them apart by
  providing lubrication when the seal operates.

• If sufficient lubrication is not obtained, then
  the lubricating fluid is supplied from outside.
  To form the thin film, it is essential that the
  two faces are perfectly parallel to each other.
• When the two faces dont remain perfectly
  parallel, then the lubricating film collapses,
  and excessive wear happens. It results in
  damaging the seals eventually.

3. EVEN WHEN THE SEAL IS ALRIGHT, IT FAILS

• There are situations when there is no problem in
  the working of a mechanical seal. Still, due to
  the heavy use, the lubrication or parallelism
  gets disturbed, and wear and tear happen.
• It happens due to some external reason and not
  because of a problem in the seal itself. For
  example, excess pressure or temperature against
  the seal due to some process upset may damage the
  seal.

4. IT IS NOT POSSIBLE TO PREVENT SEAL FAILURE

• There has been an improvement in the seal design,
  but still, it is impossible to avoid seal failure
  completely.

5. IT IS ESSENTIAL THAT THE SEAL OPERATES WITHIN
DESIGN LIMITS
There are design limits specified by the pump
manufacturers in the process manual. It is
essential to operate the seals within those
design limits.
