Still Not Sure About Switching to Sealless?

See what you know – Read this article at Fluid Handling Pro

As much as sealless pumps are very much a proven technology, some specifiers in the chemical industry remain cautious about making the changeover from conventional sealed pumps.

Magnetic drive pumps have evolved to become a cost-effective and above all safe option for the transfer of fluids including those that are toxic, pungent, extremely hot or cold, corrosive or otherwise hazardous.

Often seen as the more expensive choice, when looked at as a whole-life proposition, sealless pumps are in fact a highly cost-effective alternative.

Less Is More – When Less Means More

A simple business case:  Sealless magnetic drive pumps mean less cost and more savings, leading to greater competitive advantage.  In addition to significantly reduced costs, sealless, magnetic drive pumps bring savings in time, resources, skill sets, ongoing maintenance and also reduce the potential for lost production. They also reduce health and safety risk, and potential damage to the environment.

Making cost savings is essential to help improve profitability. Ideally, you need to cut costs faster than your competitors.  Increased competitiveness and profitability will not be made by small savings alone. You need to cut large elements of cost. To achieve this, a step-change in the technology you utilise is required.  The adoption of sealless pumps can make those savings:

 

 

When Less Means More

  • Less Time More Savings:  Time is money.  Magnetic drive pumps save the time of personnel, and money, throughout their life.
  • Less Complication More Simplicity:  Specifying magnetic drive pumps is easier.  Because there are no seals or seal support systems, plus all of the associated ancillaries, utilities, connections, instrumentation etc.
  • Less Risk More Peace of Mind: Safety first.  There is no potential for leaks or emissions, to cause environmental damage or harm to staff, visitors and the wider public by using sealless pumps.

 

Have you recently considered the cost savings and safety benefits of sealless pumps?  You may be surprised at how often sealless is now the solution, and how making a step-change in your process technology could reduce cost and so benefit your business.

We have a passion to inform the process industry about this engineering revolution and the benefits of magnetic drive pumps. Contact us today to learn more.

Think Sealless System – Why are HMD Kontro magnetic drive pumps different?

We have manufactured only sealless pumps since 1947 and so the design is specific and not a modified mechanically sealed pump.  They are made to a very robust design and engineered to last and to perform.

 

The containment shell of an HMD Kontro Sealless Pump is either of welded construction to ASME VIII pressure vessel standards with a thicker and guaranteed wall thickness or is the latest composite ZeroLoss® shell. The latter resulting in improved efficiency and reduced equipment life cycle costs.

Other magnetic drive pumps usually have hydroformed / deep-drawn shells, which are much thinner and weaker than the HMD Kontro design.  Rotating parts in our pumps are dynamically balanced ensuring smooth, quiet operation and longevity.

The magnets are fully encapsulated on the outer magnet ring, ensuring their protection from being chipped during pump re- assembly and against corrosion from the pumped liquid in the unlikely event of containment shell breach. It also means that the component can be easily cleaned in usual workshop conditions.

HMD Kontro pumps utilise a modular cartridge, which can reduce maintenance time considerably. This method of construction means that there are many common components for each product line throughout the HMD Kontro portfolio, reducing the need for a large stock of spare parts in a multiple pump installation.

Sealless pumps don’t leak, meaning that they can help reduce process inefficiencies, maximise output and minimise the risks posed to your process environment by hazardous and volatile materials.

Think Sealless System – Why are magnetic drive pumps different?

A sealless pump is similar to a conventional centrifugal pump, but without packed glands or mechanical seals. The dynamic seal that would normally be used to seal the impeller shaft is instead replaced by a static containment shell, or shroud, to form a completely sealed liquid end or pressure boundary.

 

Prime mover energy is transmitted to the sealed liquid end and the impeller by a bank of external magnets, which pass force through the containment shell to the impeller shaft.

Mechanical seals are designed to leak, maintaining their sealing capability by leaking small amounts of fluid as a means of keeping the seal faces lubricated. This leakage then reaches the environment as either liquid or vapour via a process referred to as fugitive emission.

Why would you buy a pump that leaks?!  Mechanical seals are widely regarded as the weakest point in any pumping system accounting for a high proportion of all pump failures, the remainder being leakage through static seals such as gaskets / O rings and bearing failure.  It follows that if you eliminate the problem, you eliminate the failures and save costs.

Furthermore, seals, like bearings, must wear. As they wear, the seal faces lose their effectiveness and liquid loss through the seal increases. These fugitive emissions can be costly, resulting in lost time and money, as well as decreased worksite safety.

Sealless pumps don’t leak, meaning that they can help reduce process inefficiencies, maximise output and minimise the risks posed to your process environment and people including from hazardous and volatile materials.

Without seals, which will ultimately fail, requiring expensive maintenance, sealless magnetic drive pumps represent a cost-effective and highly reliable alternative to traditional sealed pump designs.

Thinking Sealless – Process Industry Informer Podcast

Process Industry Informer is a leading magazine for managers and process engineers working in the chemical, food and beverage, pharmaceuticals and utilities industries.  They run an active podcast channel.  In a recent episode David Clark, our Senior Engineering Manager, discusses the evolution of magnetic drive sealless pumps, from their introduction by HMD Kontro over seventy years ago to the very latest developments and materials that are driving the industry forward.

Thinking Sealless Pumps Podcast

He reports how a step-change in design, driven by technology advances and innovative materials has seen the emergence of a new level of agility and flexibility while future-proofing products against ever-more stringent regulations.

The topics included in the podcast

  • Industry compliance – meeting ASME/ISO/API standards
  • Innovations including new bearing technology and use of composites
  • CSA/CSI launch – a complete redesign to meet current and future needs
  • The necessity to get products to the market more quickly
  • Future requirements for sealless magnetic drive pumps
  • Greener production – energy efficient savings of 15-20%

HMD Kontro has always been at the forefront of innovation, which is aimed at delivering what the industry needs. These include:

  • New bearing technology and use of composites:  The last ten years has seen the advent of new materials including composites to increase the efficiency and reduce the heat being put into pumps to increase their overall robustness.
  • Silicon carbide and ceramic matrix composites:  Silicon carbide has been used for over twenty years. However, over the last five years, there has been a move to use ceramic matrix composites as an alternative. This further improves the robustness of the pump.
  • PEEK composite materials:  HMD Kontro produced the ZeroLoss containment shell made from PEEK composite materials almost ten years ago. This provides a more efficient and robust alternative to traditional metallic containment shells.

The CSA/CSI Launch – A complete redesign to meet current and future needs

The catalyst for change and the development of the new range was aftermarket feedback and user comments combined with many years of experience. This led to the complete redesign of an existing product to meet current and future industry needs, involving going back to the drawing board as just a product ‘refresh’ was not going to go far enough.

A complete rethink was needed, resulting in the incorporation of the best of existing pump knowledge combined with new materials, technologies and insights. The result is a range of highly flexible pumps, which are totally configurable with the end user receiving delivery of pumps quickly, often within days.

The pumps can be brought to the market faster thanks to a modular design and configured kits of parts, allowing maximum flexibility in specification and interchangeability to minimise stockholding and to deliver shorter lead times.

Greener production

At the same time, new approaches and materials have been harnessed to improve energy efficiency by 15-20% combined with the peace of mind from total containment, as well as assisting in predicating performance issues.

How does the future look for sealless magnetic drive pumps?

There is more and more acceptance of the magnetic drive sealless pump and the future will see a demand for larger pumps with parts such as internal bearings needing to be bigger and this will demand investigation of further alternative bearing materials.  Containment shell technology is seeing more acceptance, including ZeroLoss and non-metallic shells. It is expected that HMD Kontro will continue to innovate and move the industry forwards.
