Choosing the correct oil seal application

Choosing and using the proper sealing devices within oil and gas applications can be vital when preventing dirt, dust, water, and other debris from potentially getting inside and contaminating products.  Of course, all rubber materials and seals will provide a range...

Nitrile rubber, NBR, and Buna-N – how well do you know your o ring materials?

A widely used elastomer, Nitrile, Buna-N, or NBR rubber, are all oil and fuel resistant and provide a great level of strength, making them a popular material for seals across various industries.  Suitable for a range of applications, this versatile rubber material,...

Optimum squeezing force for an o ring

It is true that the more squeeze you place on an o ring, the tighter the seal it will provide. In essence, the more squeeze (compression) you apply, the greater the force between the o ring and its mating hardware.  And ensuring you have the perfect seal is all...

O Ring Squeeze

The squeeze and shrinkage on an o ring are vital to understanding as these factors stand in the way of your application either experiencing a perfect seal or your application suffering from leaks.  You can measure the shrinkage of an o ring during...

Keeping your o rings bonded

EMI o rings. Those seal ring gaskets are made of silicone compounds, combining environmental sealing with electromagnetic interference protection.  Consisting of metal or metal-coated particles, silicone o rings are filled with silver, silver aluminium, or nickel...

How choosing the correct gasket reduces risks

Health and Safety across any industry are vital, especially so in industrial facilities and settings.  Why?  Because harmful leaks and emissions must be avoided at all costs to avoid serious accidents or injury to your teams and property.  That’s why having the right...

How to tighten your bolts perfectly

How to tighten your bolts and which tools you should use to achieve the perfect seal is not as seamless and straightforward as we would like. Various factors come into play in these situations, such as bolt grade, size, and even application type.  Tightening torques...

Static and Dynamic o rings

A range of factors and application dynamics come into play when choosing a particular type of o ring.  You need to understand the type of seal exert you require, the dimensions, and even compounds.  Due to the nature of an o ring and its overall design, o rings use...

Gasket Sealants

Fortunately, no one gasket suits a range of applications, but rather we have a multitude of gasket sealants available to meet various specifications and requirements.  Ultimately, sealants are used to effectively ensure gasket seals.  Helping to extend a gasket's life...

Types of industrial gasket material

Different industry sectors will use different types of gaskets and different types of gasket materials.   And of course!  Different industrial gasket materials will be much better suited to some industrial processes and applications compared to others.  As different...

The importance of mechanical seals when reducing water consumption in mining

The importance of mechanical seals when reducing water consumption in miningEnvironmental considerations are at the top of most industry’s agendas in the 21st century as companies evaluate and improve operations, processes, and systems. 

Conserving water in mining is one such area that is now being investigated further with the rotation of pumps and mixers and sourcing the right and highest quality sealing products that can vastly help reduce water consumption and costs at the top of the list.

Water and the mining industry 

Within most (if not all) industrial applications, for hydraulic transportation of solids, the liquid you will find used is water.  (You may find acid, kerosene, caustics, and potentially alcohol used in very rare cases, but again these are only in very rare situations.) 

However, due to where mines are located, groundwater sources can be scarce; hence there is a large cost associated with water removal and treatment to supplement this.  Then there is the negative effect that removing another water source to produce goods causes on the surrounding ecosystem and environment. 

Reducing water consumption 

The good news is water consumption can be reduced with the right pump, seal, and system in place.  

Choosing the right components for the pump sealing can vastly reduce the volume of flush water used during the mining process, with the possibility of eliminating the need for flush water altogether if the ideal mechanical seal is chosen. 

Of course, you must also consider: 

  • Equipment condition 
  • Cost of downtime 
  • Loss of product 
  • Ease of installation 
  • Techniques to reduce flush water 

Packing 

A cost-effective method when you suffer a slight leak or product dilution, packing offers an effective and quick seal. 

Depending on the application, there are three packing options available to support a flush-free sealing approach: 

Injectables – a thermoset heat-resistant material that is made up of lubricants and chopped reinforced fibres.  To provide effective sealing, the material is injected into the stuffing box through the flush port.  This material must be injected between braided packing end rings as the material itself has no strength. 

Carbon/graphite packing – graphite provides low heat generation matched with outstanding thermal conductivity and high-temperature capability.  However, extrusion can occur using this packing option.  To counteract extrusion, some graphite packing is designed with braided corners. 

Environmental controllers help reduce solids coming into contact with the packing and therefore increasing the packing life.  SpiralTrac ™ is an environmental control that can achieve such goals, reducing the amount of flush water required.  Environmental controller technologies ultimately reduce product dilution, provide a clean flush to sealing rings, and eliminate the need for a lantern ring. 

Industrial seals 

If product leakage and slurry dilution are 100% unacceptable, then a mechanical seal is your best choice.   Often requiring no seal flush water, you can save on costs associated with treatment and product dilution. 

Single mechanical seals are available and will offer you a flush-free system.  In these instances, you will see tighter face loading and clearances around the seal faces maximised around moving parts in order to prevent clogging and particle build-up. 

It’s worth noting that if solids are greater than 40% in some cases, environmental controllers should be used alongside mechanical seals to remove the larger solids, especially from the stuffing box where the seal operates. 

Split mechanical seals can provide you with a unique sealing solution, taking you beyond a flush-free operation, offering water conservation and much-appreciated ease of assembly.  Split seals are quick and easy to install and do not require the disassembling of the pump. 

Environmental controls with dual mechanical seals are required in slurry services that are a little more severe.  Using these industrial seals in conjunction with the proper environmental control will minimise product dilution considerably. 

Combining dual seals with a barrier fluid tank will offer you the greatest water conservation, as using a closed-loop system, the barrier fluid tank has no requirement for the continuous feed from an external water source, so water savings in this respect can be significant. 

If you’re looking to achieve an even greater reliability level, using an internal pump ring and a double seal will provide an even greater barrier fluid flow.
