Mechanical Sealing Spring Assembly Solutions

Spring assemblies can be an integral component of mechanical seals, and they are responsible for maintaining the sealing force needed to create an effective barrier. Spring assemblies can ensure that the sealing faces remain in contact and exert the necessary pressure, which is essential in various industrial applications where preventing leaks is critical for safety, efficiency, and environmental protection.

Benefits of Spring Assemblies for Mechanical Seals

Using springs to assist with mechanical sealing offers several advantages, making them a preferred choice for various industrial applications. Here are the primary perks of using spring assemblies for mechanical sealing:


Leakage Prevention



Material Compatibility



How Springs Support Mechanical Sealing Functions

Mechanical seals rely on a specific amount of force to maintain proper contact between their sealing faces. To generate this force, spring assemblies within the mechanical seal assembly are compressed, and the sealing faces are pushed toward one another. The spring assemblies can then enable the sealing faces to maintain consistent contact and act as a barrier against leakage.

Spring Assemblies for Sealing
  • Pumps: Mechanical seal spring assemblies can be used in pump applications, including centrifugal pumps, submersible pumps, and positive displacement pumps, to prevent leakage of the pumped fluids.
  • Mixers and Agitators: Spring assemblies can support the functions of mixers and agitators in industries such as chemicals, pharmaceuticals, and food processing to maintain a secure seal and prevent contamination.
  • Hydraulic Systems: Hydraulic systems, such as those used in heavy machinery and equipment, may rely on mechanical seal spring assemblies to prevent hydraulic fluid leakage.
  • Reactors and Vessels: Industries like petrochemicals and pharmaceuticals can use mechanical seal spring assemblies in reactors and vessels to maintain a tight seal for various chemical processes.

Why PJ Wallbank Springs for Sealing Solutions?

Manufacturers worldwide rely on PJ Wallbank Springs for reliable and effective products. Here are some of the reasons why spring assemblies can assist with their mechanical sealing operations:

  • Over time, the sealing faces of mechanical seals may experience wear due to friction and other factors. Spring assemblies compensate for this wear by continually applying the necessary force, ensuring the seal remains effective.
  • Spring assemblies adapt to variations in operating conditions, including changes in temperature and pressure. They can help maintain a consistent sealing force even when these conditions fluctuate, ensuring the seal’s continuous reliability.
  • Spring assemblies can be easy to install and integrate into mechanical seal assemblies. Their straightforward installation makes them accessible and practical for various sealing systems.
  • Springs in mechanical seals can be tailored to suit the application’s specific requirements. This includes choosing the ideal spring size, material, and spring rate to achieve the desired sealing force and effectively adapt to the operating conditions.
