CHALLENGES AND CORRECTION OF MECHANICAL SEAL
LEAK FULL CONTACT RING
2

• In the past, most of the pump shafts were sealed,
  leveraging rings of soft packing compressed by a
  precise packing gland. This category of shaft
  seal needed a fair amount of leakage to lubricate
  the explicit packing and make it cooler.
• Then came the use of mechanical seals, which
  confines product leakage across the pump shaft
  with two extremely flat surfaces. One of the
  surfaces is stationary, and the other one is
  rotating. Even though these mechanical seals also
  need some leakage, they naturally vanish and are
  not visible.

CHALLENGES ENCOUNTERED BY MECHANICAL SEALS

• A seal can be uncovered to extensive diversity of
  operating scenarios, many times very diverse from
  scenarios the seal was comprehended for, which
  can cause challenges down the line.
• Seals can even fail quicker than expected, even
  if it is the right one for the task or the
  in-hand job. To evade potential pump downtime, it
  is significant to apply the precise seal for the
  looked-for and fitting function.
• Every time of downtime leads to lost production
  with sustenance and maintenance expenses. When
  this occurs, it is significant to swiftly spot
  the cause behind the leakage. Luckily, leaking
  face seals often showcase contact patterns that
  assist in spotting the reason behind the leaks.
  Amongst the most usual of these scenarios is the
  full contact pattern.

KEY OBSERVATION OF MECHANICAL SEALS

• Full contact is the distinctive and anticipated
  contact pattern for a mechanical seal. Although
  there is full contact on the mating ring and
  primary ring exterior by 360 degrees, there is
  slight to no assessable wear on any seal ring.

SYMPTOMS OF MECHANICAL SEAL FAULTS

• The seal drips progressively whether the shaft is
  explicitly rotating or stationary and misses the
  mark of the allocated emission confines.

POSSIBLE CAUSES OF LEAKS

• Secondary seals are misappropriated on
  installation
• Secondary seals are scratched in the process 
• Dented or leaky secondary seal surfaces
• Solidity set of O-rings
• A chemical outbreak of secondary seals
• Not a low emission seal or prearrangement
• Materials not favourable to low level of emissions

MOVING FORWARD CORRECTIVE PROCESSES AND
PROCEDURES

• You can substitute secondary seals with new ones,
  cross-check secondary sealing surfaces or connect
  with seal manufacturers for authentic materials.
  The precise lead-in chamfers and burrs should
  even be cross-checked.
• The other options are to inclusively alter or
  change the seal to low emission materials,
  arrangement, structure or overall design.
