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.

High Pressure Sealless Pumps

If you, or rather your process, is under pressure, then you need the HMD Kontro HPGS,  a sealless magnetic drive pump designed specifically for high-pressure applications.  This sealless pump is particularly suitable for use in the chemical and petrochemical industries as well as site utilities.

HPGS

The HPGS magnetic drive pump can withstand system pressures of up to 2680 psi (185 bar) and is available with 7 hydraulics. It comes with a range of synchronous magnet drives, which are rated for prime mover performance. Standard construction is stainless steel with silicon carbide internal bearings although other metallic materials are also possible.

As an example application, HPGS pumps are very suitable for use when checking the density of process fluids in a high-pressure pipeline. The HPGS pump is positioned on a pipeline skid, in order to take out a sample of the fluid from the main product stream and then return it to the main pipeline after analysis through a densitometer.

HPGS pumps comply with all specifications required by the petroleum and heavy chemical industries and are typically used in toxic, aggressive, hot, crystallising and high-value processes.

Benefits of the HMD Kontro HPGS Pump include:

The Latest Sealless Technology to Improve Site Safety

CSA/CSI Modularity = Versatility / Reliability / Safety / Serviceability / Availability

The safety of your staff team and eliminating or minimising the impact of manufacturing and other operations on both the local and wider environment is an essential, legal and moral obligation.  The containment shell in a magnetic drive pump provides a complete mechanical barrier, preventing leaks, escapes and emissions. There is no reliance on any internal or external seal system or method of prevention.

When it comes to applications that involve toxic, fine, corrosive, aggressive and valuable liquids, our new CSA (ASME) / CSI (ISO) magnetic drive pumps for chemical and industrial processes deliver the ultra-safe, dependable, and reliable performance that engineers demand and that both environmental health and safety, plus industrial regulations, require.

CSA CSI Safety

In certain highly challenging applications, compliance with stringent standards calls for a secondary control or containment option to be available, completely eliminating the possibility of a leak of pumped product to escape, in the highly unlikely event of a containment shell failure. In the CSA / CSI product line we have taken the secondary control / containment options further by not only ensuring both options are available on separately mounted pumps but also on close-coupled units, which we believe is unique to HMD Kontro.

The new HMD Kontro CSA (ASME) / CSI (ISO) sealless pump range is specifically designed to be completely leak and emission-free, keeping the pumping media completely enclosed within the body of the pump, exactly where it should be.

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.

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.
