CSI chemical service pump range expands to meet demands of global ISO market

With the introduction of additional models to our CSI chemical service pump range, we are expanding our ISO sealless magnetic drive pump offering and meeting the needs of an even wider range of chemical pump applications.

The CSI chemical service sealless magnetic drive pump range has been expanded to include additional models, providing comprehensive hydraulic coverage with a total of 13 Frame 1 and 16 Frame 2 sizes.   Meeting ISO dimensional and construction standards 2858 and 15783, the expansion of the CSI range has focused primarily on additional hydraulics and a feature set which allows greater variation in the inlet and outlet sizes, allowing a wider range of flow rates of up to 120 m3/h and heads up to 62m, all optimised for high performance.

CSI Chemical Service Pump Range Expansion

HMD Kontro’s CSI sealless pumps set the standard for metallic magnetic drive ISO pumps.   With space-saving close-coupled or separately mounted/long coupled configurations, the CSI range is specifically designed to handle aggressive, corrosive, or acidic liquids in chemical applications.  With zero leaks or product emissions, the CSI magnetic drive pump is well suited to many of the pumping services found within these chemical facilities including the processing of chlor-alkali, agricultural chemicals, fine and inorganic chemicals, isocyanates, plastics, and polymers. Also, within other manufacturing industries such as battery manufacturing, water and wastewater, and petro-chemicals.

“The expansion of the CSI range ensures that we can continue to offer a world class chemical pumping solution for the ISO markets with not only the highest levels of robustness in the field but with an enhanced customer driven feature set. We can also maintain maximum pump configurability with rapid availability regardless of the specification needed” explains Hannah Verrall, Product Line Manager, HMD Kontro.

The CSI range is engineered specifically to deliver high performance and superior safety when pumping hazardous fluids.  Key benefits of the CSI and other HMD Kontro sealless magnetic drive pumps include:

  • Total fluid containment providing better environmental protection and operator safety
  • No seals or support systems eliminating possible leakage and resulting pump downtime
  • Dimensionally interchangeable options for existing installations for a more simplified procurement and commissioning process
  • Global availability and full online selection and configuration capabilities

In addition, the CSI range comes with a wide range of additional features that can be selected especially for applications requiring an additional layer of protection including Secondary Control/Containment, and the ZeroLoss containment shell, which significantly improves efficiency.

Complimenting the HMD Kontro CSI line is the new Ansimag ALI line of non-metallic lined sealless magnetic drive pumps.   All Ansimag wetted parts are moulded ETFE (Ethylene Tetrafluoro Ethylene) components that can safely handle a wide range of corrosives and solvents without corrosion.

Think Sealless Survey – The Take to Date

Survey Still Open

Thank you to those that have completed our ‘Sealless Survey’, which seeks to assess operators’ experience and to establish specifier and user priorities in terms of the benefits of sealless pumps.  The survey is still open for a few weeks for others to input and advise their opinion.

Sealless Survey Results

Early indications reveal that the primary uses stated for sealless pumps at present is for chemicals (87% of respondents) and industrial applications (46%). Collectively 52% of respondents would also consider sealless pumps for upstream or downstream oil and gas processes.

When asked which attributes of sealless pumps were considered important, specifiers cited safety as a key factor, closely followed by environmental concerns.

Process operators highlighted a range of fluids where safety is an issue, including hot fluids or high temperature processes and acids – ranging from mildly acidic to sulphuric acid and HF acid. Confidence too, was seen as a major factor, in respect of assuring zero leaks and preventing failures or breakdowns.

Additionally, with no need for seal support systems and reduced instrument wiring and configuration requirements, the magnetic drive design is easier to install and maintain, an important consideration for specifiers, with reliability and low maintenance on the list of attributes recognised as key by early survey respondents.

Think Sealless – Standards

Pumps using sealless technology can be supplied to the relevant international standards including API, ASME, ANSI and ISO. These relate to the compliance of pumps and their components in regard to efficiency, dimensions, design, testing and dynamics. You can be sure of complete compliance as our magnetic drive pumps are built to the relevant standards, without deviations. The manufacturing and design of HMD Kontro pumps is also fully in accordance with ISO 9001.

Think Sealless Standards

 

ASME Standards

ASME is the registered trademark of the American Society of Mechanical Engineers, the leading international developer of codes and standards associated with the art, science, and practice of mechanical engineering. ASME B73.3 is the ASME specification for sealless horizontal end suction centrifugal pumps for chemical processes. This standard applies to horizontal, end-suction, overhung, radially split, single-stage sealless pumps and defines both dimensional and best-efficiency head and capacity parameters (ASME B73.1 is the equivalent specification for mechanically sealed centrifugal pumps).

 

ISO Standards

This is the International Organisation of Standards and is an independent organisation that oversees, creates, and promotes internationally accepted standards for numerous industries.

ISO 15783 is this standard specifies the requirements for sealless rotodynamic pumps which are mainly used in chemical processes, water treatment and petrochemical industries. It includes design features concerned with selection, installation, maintenance and operational safety of the pumps.

ISO 2858 is an international standard and refers to end suction centrifugal pumps and specifies the main parameters and the pump designation. It specifies the principal dimensions, mounting details and nominal duty point of end-suction centrifugal pumps having a maximum operating rating of 16 bar.

ISO 5199 specifies a variety of performance requirements including minimum bearing life and construction features such as general layout and seal configurations.

 

API Standards

API sets the standards in the oil & gas pumping industries.  The API (American Petroleum Institute) standards are used to define systems, tests and equipment design and are predominantly used in the oil and gas, petroleum and petrochemical industries. Pumps that meet these standards are some of the highest quality available in industry.

API 685 relates to sealless centrifugal pumps for use in petroleum, heavy duty petrochemical and gas industry services and covers the requirements for both magnetic drive and canned motor pumps (the equivalent API 610 standard relates to mechanically sealed pumps in the same industries).

 

You can read more about the individual standards for sealless pumps and to which we work on our Certification & Compliance page. Think Sealless. For more information about our sealless pumps and their adherence to international industry standards, please browse the rest of our website.

Think Sealless Skills

How Sealless Pumps Save on Staff Time and Costs

Staff and people are a major cost of any operation. The need to employ the necessary number of people and their skill level can mean the difference between a plant being economic or too expensive to run. This key factor can be evidenced by the way that production has moved to parts of the world where employment costs per hour are lower.

Due to the simplicity of a magnetic drive sealless pump, the ease of commissioning and minimal maintenance requirements means that not only are less people required but also that significantly less specialist skills are needed. This makes them eminently suitable for plants in areas where skilled people may not be readily available.

 

The minimal maintenance also means that less man hours are required per servicing and for any routine requirements.  Even when specifying sealless pumps less design time is needed, with fewer HAZAOPS considerations, less system documentation and minimal specification of instrumentation.

To save staff time and costs, Think Sealless. Please see www.thinksealless.com.

Think Sealless Safety

Why sealless pumps are safe and secure

Minimising the impact of manufacturing and other operations on your staff plus the local and wider environment is an essential, legal and a moral obligation.

 

Any leak is a potential hazard. Sealed pumps, by their operation, are designed to leak. They often also require seal support systems, which have the need to be maintained and topped up on a regular basis.

Sealless pumps are self-contained. The pumped product or liquid is completely enclosed within the body of the pump. The containment shell provides a complete mechanical barrier, preventing leaks, escapes and emissions. There is no reliance on any external system or method of leak prevention.

Lower-cost alternatives often require additional systems and ancillaries, all of which also have the potential for leakage, spillage and cross-contamination. Some even require that the recovered liquid that has been emitted, for example, across the seals, be captured and disposed of safely, which in itself incurs further restrictions.

Health & safety is everybody’s responsibility, from the production and maintenance staff on the shop floor right up to the members of the board.  Magnetic drive pumps are hermetically sealed  eliminating the risk of leaks or emissions and so offering significant health and safety advantages.

Think Sealless – Simple Servicing

Why sealless pumps are simple to service and maintain

Thanks to a modular construction and the ability to dismantle HMD Kontro sealless pumps without special tools, periodic servicing and maintenance of magnetic drive pumps on-site is simple and straightforward.

 

The simple design of HMD Kontro sealless pumps also means that they are usually site repairable with minimal maintenance skills required. Other benefits include:

  • No complex seals or sealing systems.
  • Easy cartridge replacement.
  • Only basic tools are needed.
  • No need for vibration monitoring.

The unique HMD Kontro cartridge design means minimum spares. Indeed, the modular construction and many common components, such as the liquid end bearings, means less spare parts stock and inventory for further reduced operational costs.

Reduce your servicing skillsets and make savings. Think Sealless. Think HMD Kontro Sealless Pumps.

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.

To learn moreThink Sealless

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.

 

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.

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.
