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.

Performance Under Pressure!

When the pressure is high, such as in densitometer sampling and similar applications, the high pressure HPGSP range are the perfect pumps.

Original equipment manufacturers worldwide have discovered the benefits of the HPGSP pump when checking the quality of the product passing down a high-pressure pipeline. The pump is used on these densitometer skids to take a sample of the fluid out of the main product pipeline, which can be up to 2m / 80” in diameter, and return it after analysis.

Many of these pipelines and metering stations can be located in remote regions. Therefore, a pump with no mechanical seals or seal support systems, with non-wearing silicon carbide bushes and a duty point that, once the pump is set, does not need adjustment, is great from a service viewpoint. The HPGSP pumps are fully compliant with the requirements of API 685.

The HPGSP pump’s ability to withstand high system pressures, together with its sealless construction, providing enhanced safety in operation, means that the HPGSP eliminates the need for expensive callouts, downtime and repairs associated with mechanical seals, which can be very expensive for this application.

The HPGSP range is a comprehensive family of pumps able to withstand high system pressures up to 185 bar / 2700 psi and flow rates of 290 m3/h / 1500 USgpm, suitable for applications involving volatile products such as crude oil, diesel, jet fuel, condensate, propane, as well as other similar petrochemical products.

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.

Think Sealless – WHAT is a Sealless Pump?

Essentially, sealless pumps are centrifugal pumps without packed glands or seals. Instead of a seal, there is a static containment shell or shroud, which forms a completely sealed liquid end or pressure boundary.

Prime mover energy is transmitted to the sealed liquid end by a bank of external magnets, which pass force through the containment shell to the inner magnets attached to the impeller shaft, meaning there is no risk of leaks or emissions.

Sealless v Sealed Pumps

It’s necessary to understand what a mechanical seal is to differentiate between the two types of pump. Mechanical seals are designed to maintain their sealing capability by leaking small amounts of fluid in order to keep the seal faces lubricated.

Mechanical seals are widely regarded as the weakest point in any pumping system. In fact, they account for 80% of all pump failures, with the remainder being leakage through static seals such as gaskets or O Rings and bearing failure.

Seals, like bearings, will ultimately wear and, 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 reduced worksite and environmental safety.

WHAT makes a HMD Kontro Sealless Pump different?

  • Welded metal containment shell to ASME VIII pressure vessel standards
  • Optional ZeroLoss® shell. To improve efficiency and reduce life cycle costs
  • Dynamically balanced rotating parts for smooth operation and longevity
  • Modular cartridge construction reducing maintenance time
  • Many common components reducing spare part inventory
  • Fully encapsulated outer magnet ring for protection and easy cleaning

It Can Take The Heat! The CS Sealless Pump For Heat Transfer in Hot Oil Systems

A Unique Sealless Pump for Heat Transfer in Hot Oil Systems

Isolating the pump from the heat source has usually been essential in a hot oil system.  However, thanks to its unique torque ring, our CS pump requires no cooling fluids or heat exchangers during operation.

The CS Sealless Pump is the perfect choice

The pump is totally self-venting and the magnetic coupling is immersed in the hot oil. Not only that, the torque ring design offers a built-in soft start for viscous liquids, and the energy created adds to the efficiency of the system.

Simple to operate and maintain, cost-effective to run and capable of operating up to 350°C / 660°F without cooling as standard (a 450°C/842°F option is available on request), this all makes the HMD Kontro CS sealless pump the ideal choice.

Benefits of the CS Pump

  • Ideal for heat transfer liquids
  • Sealless design provides total product containment
  • No product cooling required for temperatures up to 350°C / 660°F as standard
  • One fully confined Casing Gasket to eliminate ‘blowout’ risk
  • Built-in soft start feature, which is ideal for viscous start up

In addition, the torque ring drive positively contributes to the efficiency of the hot oil system and the CS can also be used in toxic, aggressive, hot, crystallising and high value processes.

The recent upgrade of the outer magnet ring (OMR) on the CS range now offers significant additional advances in magnetic coupling robustness, leading to increased MTBF (mean time between failure), reduced downtime / increased uptime and increased operational efficiency.

The OMR upgrade maintains similar performance and maintains reliability

The retro-fittable OMR provides shielded magnets that retain the same level of performance and eliminate any potential for damage.  The new OMR has improved cyclic thermal duty whilst the identical coupling power produced means that the upgrade maintains similar performance to maintain reliability.

The encapsulated magnets on the OMR are made of samarium cobalt and have increased resistance in corrosive applications.  They also provide higher efficiency by reducing slip and improved reliability because no tie bolts are used in the retention of the magnets.

However, these are now coming further to the fore due to recent and more stringent environmental, health and safety requirements. For the Guide to Sealless Magnetic Drive Pumps click here.

Environment, Health and Safety (EHS)

In these days of increasing EHS concerns, and the resulting legislation and litigation, leakages of process product can cause significant problems. Damage can be caused not only to personnel and property onsite, but also to reputations, plus also the loss of production uptime and valuable productivity.

Choose the safe option – a sealless magnetic drive pump

Unlike pumps that include a mechanical seal, which is designed to leak a little for lubrication, but which could also fail, a sealless pump is the safe option. With a sealless pump, the product is completely contained at all times with no potential for leaks, no escapes to the atmosphere, no emissions, no health issues, no safety concerns and no environmental hazards. No How!

A virtual lack of maintenance and repair meaning less downtime

A further advantage of the sealless pump is the almost complete lack of maintenance and repair required. Not only does this reduce the work and requirement for routine and replacement parts, it also eliminates the associated downtime.

Sealless pumps are now an option on new applications

You may be surprised. The capabilities and operating parameters for sealless pumps may well now be much higher than you think. As a result, they are finding many new applications and are often being used on installations where traditional mechanical sealed pumps would be first considered.
