Chesterton’s SpiralTrac™ Revolutionises Slurry Sealing Solutions

Category: Mining

Slurry pumps are only as good as their seals. As every industry operator knows all too well, the replacement and maintenance of packing and mechanical seals often represents extended asset downtime and the related loss of revenue during lengthy upkeep procedures.

Enter Chesterton, fluid sealing and equipment protection specialists, with an innovative remedy to this historical problem – the game-changing SpiralTracTM. Designed to work with both packing and mechanical seals, the unique design of this environmental controller is simple to install and greatly enhances sealing reliability that can be utilised within all rotating equipment.

So let’s delve a little deeper into why this is such an advantageous addition to the slurry industry.

The Challenge

Ensuring patent seals within operational assets is crucial to a company’s bottom line. However, in an industry where the integrity of seals or their packaging can be measured in weeks or, in harsh conditions, as little as days, the challenge of ensuring optimal production is further compounded by having to deal with multiple suppliers to meet their needs.

No matter what type of seal is in use, it’s generally recommended to replace mechanical packing or service mechanical seals. However, in reality, this can be a time consuming and difficult task. This often leads to less than ideal practices, such as leaving lantern rings in place while repacking the rings above.

Add in the, at times, difficulties of installing mechanical seals and determining the best solution for the particular rotating machinery in use, and it’s easy to see why various short-cuts often become the norm to keep downtime to a minimum and production at a maximum.

The Solution

The way forward was to draw up mechanical seal and mechanical packing standardisation guidelines for the slurry industry. This was done through a program of expertise and the ability to effectively produce not only the mechanical seals and packaging, but an effective solution that extended the life of both and had a positive impact on the many environmental aspects related to slurry.

The real lightbulb moment came with the creation of the industry-changing SpiralTracTM environmental controllers. This simple, yet highly-effective addition enhances sealing reliability thanks to removing solids and improving the cooling of the stuffing box. In turn, this extends both seals and packing reliability and also reduces the cost of flushing in abrasive applications.

Of course, despite its complex role, it was imperative that the addition of SpiralTracTM with packing and mechanical seals was easy to install. The end result was a range of environmental controllers to be used with either mechanical seals or packing, and that offer the following:

  • Installation requires no modifications to the pump or seal cavity
  • Available in split versions
  • Split design installs easily in the seal cavity
  • Greatly reduces the flush
  • Can be easily installed between the seal and seal cavity
  • Multiple configuration options
  • Enables venting of air from the chamber

With a variety of designs and that can be used with all slurry rotating applications, advantages over and beyond that of the purchase price soon become apparent. These include:

  • Longevity of seals, packaging and shaft sleeves
  • Less downtime
  • Less maintenance costs
  • Conservation of water
  • Power saving
  • Simple repairs
  • Increased reliability
  • Strong resistance to chemical aggression and abrasion

Chesterton’s far-reaching expertise that spans the globe yet provides a truly local service has been crucial in the provision of such a ground-breaking solution. Technological advances and industry-specific knowledge have been tantamount in the production of a variety of slurry focussed mechanical seals and mechanical packing. By creating a range of leading seal solutions that offer simplified installation, improved reliability and extended performance, customers can easily target their bespoke application needs.

Seals and solutions on offer include:

With application parameters that support extremes of temperature and pressures, as well as a variety of capacities and in varied conditions, the use of SpiralTracTM is proving hugely beneficial to organisations that have taken advantage of this innovative opportunity.
