Which is the Better Seal - Gland Packing or Mechanical Seal?

Gland packing and mechanical seals both are extremely important parts of pumps and shafts. Numerous engineering applications count on these devices to appropriately function.

Although seals and packings have comparable functions, utilizing either depends on spending plan, personal preferences, and more notably, application requirements. Rotary pumps work best with seals because they are capable of collecting, dealing with, and filtering fluid leak. On the other hand, there are applications where a packing is the better suited choice, such as settings with corrosive surrounding, which occur to cause seals to deteriorate faster. A packing will last longer if this is the case.

There are several other benefits and drawbacks to utilizing either seals or packing. Below is a brief comparison in between a gland packing and a mechanical seal.

Gland Packing - Does It Do the Job?

Gland packing is also called the standard shaft seal. Many engineers don't recommend packings for a great deal of applications due to the requirements and expenses of maintenance. Sealing off gases or liquids isn't as efficient either, as a packing is susceptible to occasional leakage. You have to routinely change so that the seal is well-lubricated.

There's also the issue of abrasive liquids triggering deterioration. This typically takes a toll on the life expectancy of a gland packing, hence forcing you to invest more on repairs and replacements.

On the bright side, there are cases where packings out perform seals. They're great with dealing with aggressive fluids, for example. Packing makes another point due to its performance in case there is leak due to the fact that it's simple to adjust to keep the pump fully functional. Because you 'd have to take the pump out of service, you can't do this with seals.

Applications that involve ball valves, valve, gate, and world cocks also enter favour of packing because seals require rotary movement to be able to seal anything. It is precisely this factor that gland packings are integrated in reciprocating pumps.

Mechanical Seals - What Makes Them Any Good?

When it concerns appeal, seals win. They are carried out in a lot more applications partly because they cause very few leak problems, and they are practically maintenance totally free.

Since they have considerably low energy consumption, sticklers for power intake might likewise be inclined to use seals more. Thanks to the couple of leakages, seals rarely experience disruptions, thereby saving time and effort.

Other elements of a seal's toughness are the period of the sealing operation, ambient temperatures, and the liquid being pumped. Pressure and temperatures trigger progressive damage for both seals and packings, particularly with mechanical seals. If seals are your option for sealing devices, keep in mind that unexpected dry running might make seals weaken quicker.

The rate of seals might likewise discourage you since they are a lot more expensive than packings.

Which to Choose

At the end of the day, the best method to approach this is picking the sealing equipment that can get the job done with very few troubles. Whether you pick gland packing or mechanical seals, make an educated decision so that you can avoid snags in your budget and productivity.
