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.

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.

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.

Now with Longer MTBF for Increased Operational Efficiency

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.
