It's All About The Seal: Solutions for reliable mining & ore processing

It's the little things in life that count, and in the world of mining they don't come much smaller that the seals that drive the efficiency of rotating, stationary, and fluid power equipment platforms.

When it comes to reliability, much effort is directed to the larger components so vital for processing ability. However, a failure to pay the same devotion to the quality of the sealing solutions within these assets can lead to a variety of unfavourable outcomes, including:

  • Reduced lifespan of components
  • Lowered productivity
  • Increased maintenance costs
  • Unnecessary repairs
  • Catastrophic failure incidents

When considering the ultimate in hydraulic seals for example, it's necessary to focus on the four following attributes:

  1. The seal material: Overwhelmingly, the most important improvement that can increase reliability is to upgrade the material that the seals are made from. A high-performing polymer ensures the ultimate suitability to the fluids within a system, the environment, the equipment itself and the operating conditions.
  2. The seal profile: This must be designed for the specific application, be able to effectively withstand high stresses and of the correct size to fit the equipment.
  3. The bearing components: The ability to handle incredibly potent radial forces is key for seal protection. Bearings should also keep contaminants out and prevent any metal-on-metal contact within cylinders.
  4. Configuration of the seal system: Customised, application-specific solutions designed by engineers is the crucial difference that ensures the highest level of performance.

Together, these key components of hydraulic sealing are what makes a very real difference in asset longevity, output, lowered maintenance costs and reduced downtime.

When determining the right seal solution, it's vital to ensure that all four of these factors have been adequately addressed. Only by selecting those that've been wholly designed in such a manner will the outcome be improved, thanks to reliability combined with maximum mining and ore processing performance.

The following lines in sealing solutions combine all of these attributes and are giving companies the crucial edge over their competitors.

Hydraulic and Pneumatic Sealing Solutions

Cutting edge polymer technology has been tested and embraced by those who demand the highest level in sealing applications. Such solutions extend the longevity of hydraulic seals, meaning machinery can work for longer before needing maintenance. Unique seal geometries are applied to both custom and turnkey cylinder repair kits, so improving productivity and consistency.

Mechanical Seals: Pumps, mixers, agitators, and rotating equipment

Utilising the four crucial components mentioned above, the highest grade of a variety of seals can be determined to achieve the most cost-effective and long-term solutions. These include:

  • Cartridge seals
  • Split seals
  • Gas seals
  • Dual seals
  • Mixer seals
  • A variety of sealing support solutions


Lubrication/MRO Specialities

Getting the crucial aspect of lubrication correct has a hugely beneficial impact on performance and production. Taking advantage of technologically advanced industrial lubricants, automatic lubricant dispensers, cleaners and greasers is the key component to ensure seal longevity.
