Different Types of Mechanical Seals

• In any centrifugal pump, there are various
  components. But mechanical seals are one of the
  critical components. They preserve the integrity
  of the pump system because seals prevent fluid
  leakage. Thus, they keep contaminants out of the
  system. Mechanical seals are used on several seal
  designs to detect leakage and control the sealed
  environment. Three types of mechanical seals are
  used in process equipment Cartridge. Component.
  Air.
• Depending on the type of centrifugal pump and the
  process variable, various types of mechanical
  seals are used. Each seal variant has some unique
  design and characteristics. They make the seal
  suitable for a particular application.

• Various Types of Mechanical Seals for Centrifugal
  Pumps
• Balanced seals
• Unbalanced seals
• Pusher seals
• Non-pusher seals
• Conventional seals
• Cartridge seals
• Lets know the highlights of various types of
  seals and their benefits and limitations.

Balanced and Unbalanced Seals

• In a Balanced Mechanical Seal, the forces acting
  on the faces of the seal are balanced. When the
  lower face gets loaded, there is more even
  lubrication of the seal faces. These seals last
  longer. Balanced seals are more suitable for
  applications where the operating pressure is
  high. They are ideal for handling liquids with
  high volatility and low lubricity.

Pusher and Non-Pusher Seals

• In Pusher seals there is one spring or multiple
  springs to maintain the seal closing force. The
  springs can be in the rotating part or the
  stationary part of the seal. Pusher seals offer
  high-pressure sealing but there is a probability
  of wear of the spring. The wear is high because
  the seal face moves along with the shaft or
  sleeve.
• In a Non-Pusher seal, there is an elastomeric or
  metal elbow to maintain the seal closing force.
  For applications where the temperature is high,
  these seals are suitable. They can be used in
  dirty applications also. The only thing is they
  can be used in applications where pressure is low
  or medium.

Conventional Mechanical Seals

• Conventional seals are low-cost. They are
  installed in general service equipment. The skill
  required is higher to use the skills because they
  are installed as an individual component.

7
Cartridge Mechanical Seals

• These are composite seals where all of the seal
  elements are incorporated in one single unit.
  They reduce the chances of errors in assembly.
  Also, the time for seal replacement is lesser
  than for other types of seals.
• Beston Seals is ISO certified company specializing
  in providing solutions to all types of leakages
  by manufacturing mechanical seals and sealing
  components as per customers drawings, samples,
  or requirements. We are one of the best rotary
  union and mechanical seal manufacturers in
