1. 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.

3. 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.

4. 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.

5. 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

6. 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.
