Difference Between Mechanical Seal and Gland
Packing

• Here we describe the difference between
  mechanical seal and gland packing. With the
  development of technology, new and advanced
  sealing methods are getting introduced. The
  sealing technology is also evolving and improving
  every year. For many years, gland or packing
  seals have been the first choice. However, in
  recent years, mechanical seals are also being
  considered for operational benefits.

What are the key differences between these two
types of seal seals?

• Both gland packing and mechanical seals are
  effective and useful. It depends on economic
  viability, personal preference, and requirement
  specification which one will be preferred? Here
  you know the difference between mechanical seal
  and gland packing.

Gland Packing Seals

• As mentioned before, gland packing seals have
  been widely used for many years. These seals use
  rope-like material, which is wrapped around the
  shaft of the pump. It fills in dead space and
  minimizes fluid loss.
• When the gland packing material wears out with
  age, fluid loss increases. It will result in
  impaired lubrication and reduced ease of
  replacement needed for proper functionality.

Mechanical Seals

• They are preferred over traditional packing seals
  in diverse applications where leakage avoidance
  is crucial. These seals are more durable as
  compared to Gland Packing Seals. Also, they are
  designed to take more punishment. Since there are
  multiple sealing points to eliminate leakage
  issues, they are better than gland packing seals.
• One sealing point stays fixed here, whereas, the
  other rotates with the shaft. As the lapped faces
  collapse, the fluid leakage is stopped by
  an O-ring, V-ring, or wedge.

When is a packing seal used?

• Packing seals are typically the most economical
  choice for sealing solutions. It is the reason
  they are widely used. They are easier to install
  than mechanical seals. There is no need to
  decouple the driver shaft. Hence, you have a
  considerably shorter installation time as
  compared to other types of seals.
• These seals can adapt to the conditions and
  maintain the integrity in pumps and agitators
  where a large amount of radial movement is there.
  In mining and ore processing, packing seals are
  an economic choice.

When is a Mechanical Seal used?

• Mechanical seals are ideal when seal leakage is
  not an option for application or equipment. It is
  usually the case when pump leakage may cause
  safety hazards or environmental issues. These are
  more durable than packing seals. Hence, a better
  choice for long-term operation.

• Though mechanical seals are costlier than packing
  seals, you save on the cost of constant packing
  seal repair and replacement. Mechanical seals
  minimize sleeve damage.
• Both types of seals have pros and cons. It is
  important to check the sealing requirement before
  picking one. Based on the needs of the
  application, a suitable type of seal is selected.
