High-Precision Double Mechanical Seal Agitator and Mixing Equipment Operations

Double mechanical seals used for agitators significantly differ from double mechanical seals used in standard pumping systems. Mixing and agitation equipment may have dissimilar shaft dynamics and operating conditions than standard pump systems; for example, agitators typically work with vertical shafts and apply variable loads, and as a result, undergo frequent process changes. As a result, double mechanical sealing configurations support the axial movement and include intermediate sealing spaces that assist with stable operation.

Advantages of Double Mechanical Seal Agitator

Increased Stability of Agitator Shaft

Double seals provide tolerances for the vibration and deflection of shafts associated with an agitator.

Increased Safety During Operation

Double or tandem sealing will allow a process to continue to operate when the first seal is failing, thereby providing additional time to source replacement parts.

Flexible for Any Complex Equipment Arrangement

Tandem seals may be arranged in multiple ways that will accommodate vertical shafting, horizontal shafting, or a combination of both.

Double Mechanical Seal Agitator

Application Scenarios

The application of double mechanical seals agitator goes beyond the pumping industry to include applications where there is increased risk from shaft movement and process failure as well as to provide additional protection.

Typical applications include:

  • Agitators and mixers that have vertical shafts and carry a varying load
  • Processes that require agitation of a fluid or viscous material and therefore may have increased movement on the shaft
  • Tandem mechanical seal arrangements that are utilized to provide additional safety through staged sealing
  • Installations of equipment that are utilized have a secondary form of protection in the event of a failure of the primary seal

All of these applications are primarily concerned with providing a means of continuous operation and controlled failure as opposed to minimizing costs.

FAQ

What benefit does a double mechanical seal provide to agitators?

Agitators experience greater levels of movement on the shaft and therefore require double seals to maintain stable sealing conditions.
Tandem mechanical seals are seals that are set up in a series configuration in order to enhance safety and reliability.
Yes, the correct alignment of the shaft, the support system for the shaft, and the operational parameters for the agitator must all be taken into account.
