Think Sealless Situations

For situations involving high temperatures, high pressures and volatile substances, plus many more where regulations are strengthening and safety is paramount, magnetic drive pumps are the clear choice.

When it comes to these applications in the chemical, oil, petroleum, gas production, agrichemical, pharmaceutical and general process industries, including those that involve toxic, fine, corrosive and aggressive liquids, our sealless pumps deliver the rock-solid, completely leak-free, performance that engineers demand and that industrial regulations require.

 

Thanks to the complete containment of the liquid, sealless pumps, are suitable for pumping the vast majority of liquids, especially those applications where fluids present difficult and/or costly sealing challenges.

Examples include: acids, solvents, fluids under pressure, heat transfer fluids, volatile liquids and oil, hazardous liquids and expensive fluids. Also, those fluids are pungent, radioactive and crystallising.

You can find out more about the applications and parameters of our pumps on our sealless sectors website page.

Pumps & Printers

Switching to sealless pumps can make substantial savings.

A sealed pump is a bit like a printer – With a printer, you are often amazed at how little you pay for the machine itself, but that’s because you are then paying for expensive cartridge or toner replacements.

Pumps & Printers

A conventional sealed pump is similar, the cost is lower, although often not by much compared to a magnetic drive pump, but there are high ongoing costs. This means that through the lifetime of the pump, you will pay substantially more.

Sealless pumps are really ‘fit and forget’, unlike sealed pumps that need constant seal replacement and maintenance, with all the associated costs.

Why You Should Switch to Sealless

The mean time between failure (MTBF) for magnetic drive sealless pumps is typically three times that of mechanically sealed pumps.

According to a report by the United Kingdom Health and Safety Executive, mechanical seals are widely regarded as the weakest point in any pumping system that uses them. They account for 80% 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. HMD Kontro sealless pumps are magnetically driven, they have no mechanical seals or seal support systems, and only a single, fully trapped gasket that ensures systems integrity, even at high temperatures and pressures.

 

Sealless pumps are easier to maintain, have fewer working parts, no potential leak paths and no support systems to design, install and maintain. There is less time and cost involved in system design and procurement plus no concerns regarding material compatibility or appropriate buffer liquids.

By specifying HMD Kontro sealless pumps you can be absolutely positive that you have made the right decision. Combining cutting-edge technology with over seventy years of expertise and experience, since we were the first in the world to develop the concept, our magnetic drive pumps provide complete peace of mind.

Think Sealless Savings – Why Sealless Pumps Save Money

Sealless pumps bring savings in time, resources, skill sets and ongoing maintenance, whilst also reducing health and safety risk and potential damage to the environment.

Time is money.  Whether you are the consultant, contractor or the client, reduced design and specification time, even the benefit of less HAZOPS and monitoring procedures, will contribute to faster project times. These then translate into lower costs and quicker implementation, such that a new or refurbished plant can be up and running much faster.

 

With sealless pumps, savings can be made at every stage of the project: design, engineering, procurement, installation, documentation and commissioning.  Then the time savings continue once the pumps are up and running. Less maintenance, longer time between failures (MTBF) and a more rapid return to operation, all contribute to enhanced profitability and margins.

Examples of how costs can be contained include the following:

  • Lower Installation Costs: No Large baseplate and foundation required, no Cooling water piping, less instrument wiring and connections, less instrument configuration (DCS) and no barrier fluid (first fill).
  • Lower Project Costs: Lower Project Costs: Less documentation for system and instrumentation with shorter specification times thanks to quicker HAZOP meetings, due in part to there being no need to consider the PED (Pressure Equipment Directive) and SIL(Safety Integrity Level) requirements.
  • Lower Operating Costs: No Repair or replacement of seals and bearings, no replenishment of barrier fluid, no maintenance hours to operate and maintain seal systems and less lost production during downtime, no removal of barrier fluid from product and no maintaining of seals on stand-by pumps.

 

The adoption of sealless pumps can achieve the step-change savings that are needed from concept to completion of your project and beyond, throughout the life of the pump.

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.

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.
