The International Organisation for Standardisation is an independent organisation that oversees, creates, and promotes internationally accepted standards for numerous industries, ranging from agriculture and manufacturing to technology. ISO safety symbols are recognised across all countries and in all languages for increased hazard awareness and safety compliance.
The ISO 15783 standard specifies the requirements for sealless rotodynamic pumps which are mainly used in chemical processes, water treatment and the petrochemical industries. It includes design features concerned with the selection, installation, maintenance and operational safety for magnetic drive pumps.
The ISO 2858 Standard refers to all end suction centrifugal pumps and specifies the main parameters and the pump designation. It details the principal dimensions, mounting details and nominal duty point of end-suction centrifugal pumps having a maximum operating rating of 16 bar.
The ISO 5199 standard specifies performance requirements including minimum bearing life and construction features such as general layout. In some aspects, including maximum permissible vibration levels, ISO 5199 is more stringent than ASME B73.1.
HMD Kontro pumps comply with all relevant aspects and specifications of ISO pump standards. In addition, our manufacturing and business processes also comply with ISO 9001, 14001 and 45001 standards. Additional details are shown on the certification and compliance page of our website.
For further information on HMD Kontro sealless pumps built to the ISO standards, including the CSI, GSI and GTI ranges, please take a look at the products section of our website.
Hydrofluoric acid alkylation poses particular challenges to process operators, requiring special care in the handling of HF Acid, a lethal, highly corrosive fluid that poses a potential hazard to plant equipment, the people who work on site and the wider environment should a leak occur.
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate: a high-octane additive and critical safety component that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies.
As reviewed online by World Pumps, HMD Kontro’s next generation pumps have been refined using new materials and technologies to provide an effective solution. The result of close collaboration between UOP Honeywell, the leading licensor of HF alkylation technology and using an innovative development process, the HMD Kontro HF pump features a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW).
This has been tested using new methods of Non-Destructive Examination (NDE) and has been proven to offer the necessary resistance to corrosion to meet NDE standards. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the possibility of leakage into the environment, and reducing operational risks and the associated costs to meet the industry’s stringent environmental and health and safety goals.
A broad range of hydraulic sizes for a wide range of applications
The CSA (ASME) and the CSI (ISO) magnet drive end suction centrifugal pumps are a modular range of chemical pumps that cover a wide range of hydraulics. Initially, the CSA / CSI pump range will provide comprehensive hydraulic coverage for flows up to 64 m3/hr / heads to 60 m for the CSA (ASME), and 130 m3/h / 60 m for the CSI (ISO). This will be extended to flows up to 600 m3/h and heads to 140 m with the next phase of the product launch later in 2022.
The range is based on multiple hydraulic sizes that fully conform to the dimensional, performance and construction requirements of ASME B73.3, ISO 2858 and ISO 15783. Close coupled and separately mounted variants are available across the entire range.
The broad choice of hydraulics ensures that a wide range of applications are catered for, and for convenience and ease of onsite service, this scope of hydraulic sizes is designed for maximum part interchangeability. The range also has a wide number of site upgradeable features.

As industry leaders in magnetic drive pump technology, the HMD Kontro range includes the vertically-orientated GSPV, a magnetic drive sealless pump that requires minimum floor space and offers a sealless upgrade solution to vertical inline pump installations. Highly configured, yet meeting standard API 685 requirements, the GSPV has been engineered with a high attention to detail, thereby offering a strong alternative to conventional mechanical sealed pump designs.
In a recent webinar, Charlie St Laurence explains how improved magnetic drive technology has increased the application scope for vertical inline sealless pumps.
With nine hydraulics split between two frame sizes, and a standard design pressure of up to 40 bar /580 psi, the GSPV is ideal for offshore installations where space is at a premium and for crude oil, pipeline or fuel terminals’ he explains.
When planning a new pump installation or an upgrade at an existing site, the opportunity to switch from sealed to sealless brings significant cost savings and wider benefits.
How does the GSPV deliver technically?
Utilises a closed impeller and radial diffuser
Rated to 40 bar/580 psi
Max temp 205 C/401 °F
Radial Diffuser offering High and Low flow versions
Dimensionally compliant to BS4082
CMC thrust bearing material comprising of a silicon oxy-carbide matrix with continuous carbon fibre reinforcing.
Compatible with ZeroLoss Shell (meaning no coupling power loss)
How easy is it to take advantage of the GSPV upgrade and replacement opportunity?
The GSPV presents the perfect opportunity to make the migration to sealless, to simplify installations and to make cost savings. With a longer MTBF, and no bearing box required meaning no potential oil leaks, a GSPV replacement can overcome common problems and troubles users have consistently outlined with mechanical seals. For more information on the GSPV, and to listen to a full webinar presentation, please see the video below.
Secondary Control & Containment Options for Complete Confidence
The CSA and CSI ranges of ASME and ISO sealless pumps provide complete containment of the liquid being pumped as standard. However, some situations and some regulations demand an even higher level of protection, which can be offered by a secondary level of control or containment.
Fully compliant to ASME requirements and available on both close coupled and separately mounted configurations, providing a secondary level of control or containment gives further enhancement of the pump and product integrity leading to even higher environmental, health and safety protection.
Suitable for use throughout the CSA / CSI pumps operating temperature limits, the provision of a secondary housing designed for up to 275 psi / 18.9 bar pressure, provides additional security to guard against a breach in the primary pressure boundary. This is particularly useful for those processes involving highly hazardous materials.
In keeping with the modularity of the CSA and CSI range, secondary control and containment is available as a site upgradable feature allowing standard pumps to be enhanced at a later date.
For further information and to watch a video on secondary containment, please click here. Please see the CSA / CSI section of our website for further details.
PEEK Containment Shell Eliminates Eddy Current Heating and Improves Pump Efficiency
Reduced power consumption and hence energy savings, bringing a lower carbon footprint, is one of the significant reasons why the ZeroLoss containment shell is being specified on more and more HMD Kontro pumps, including the CSA / CSI range for chemical applications. ZeroLoss also brings improved handling of liquefied gases and heat-sensitive liquids.
The PEEK (Poly-Ether-Ether-Ketone) composite containment shell is highly durable, combining low weight with a higher specific strength, which will withstand a pressure of almost 19 bar / 275 psi.
Induction losses, associated with a traditional metallic containment shell, are completely eliminated, so allowing significant energy savings during operation. This can often also contribute to lower capital and installation costs because a smaller motor can be used to drive the pump, so also saving space.
Another benefit of the ZeroLoss containment shell, versus a metallic shell, is that less heat is transferred into the liquid being pumped. The CSA / CSI, when fitted with a ZeroLoss shell, can accommodate temperatures of between -40°C and up to 120°C / -40°F to 248°F.
The ZeroLoss shell is provided with a built-in vortex breaker, within the crown, to eliminate shell erosion. For further information on ZeroLoss, please click here. For further information on the CSA / CSI range of ASME and ISO chemical pumps, please click here.
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.
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.
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.
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:
Sealless design for total product containment
Modular / interchangeable high-efficiency wet end
Provides maximum flow and head coverage
Flows to 70 m³/hr / 308 gpm
Heads to 70 m / 230 ft
Temperature range -40 to 205°C / 400°F
High-efficiency magnetic couplings
For further information, please see the dedicated HPGS page.
The new HMD Kontro CSA/CSI range of pumps represents a significant leap in sealless pump technology with its modular design and interchangeability of component parts. Specifically designed for ease of configuration and upgrade, the range has been developed to maximise uptime while delivering cost savings through improved lead times and operational efficiencies.
The new CSA/CSI range is distinguished by its extremely wide operating parameters. The extended space and shaft design of its new external bearing assembly provides resistance at temperatures from as low as -40°C/F up to 260°C / 500°F. Withstanding design pressures of up to 19.0 bar / 275 psi at 38°C / 100°F, the CSA / CSI pumps offer flow rates up to 77 m³/h / 340 USgpm and can process liquids with a viscosity from 0.1 – 200 cSt.
A wide range of high-efficiency hydraulics ensure maximum flow and head coverage for optimal productivity. Low and high hydraulic variants are available to ensure an optimised fit, improving production flow rates and delivering cost savings.
The ‘Frame 1’ naming convention denotes a pump with B73.3 dimensional designations making the CSA/CSI an excellent upgrade path for switching from a mechanically sealed to a sealless pump. Think Sealless!
Please visit the CSA/CSI section of the website for more information, including detailed product specifications, then contact us for where you can purchase or with any questions.

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.
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.
The SPGS pump is a self-priming sealless pump designed for reliable transfer of fluids ranging from water to hazardous and toxic substances.
The SPGS is particularly suitable for offloading liquids where total containment is crucial including emptying sumps, road and rail tankers.
The product line covers a hydraulic range that is split between two frame sizes, with standard construction being 316 stainless steel and silicon carbide internal bearings. Other material options are also available, such as; Alloy 20 or Alloy C, with PTFE gaskets.
Benefits of the SPGS pump include:
Self-priming capability ensures the safe offloading of liquid.
Increased efficiency liquid ends for lower running costs.
Many compatible spares with other HMD Kontro GS range pumps.
Simple installation and easy to maintain onsite.
The larger Frame 1 version of the SPGS will handle flows to 25 m³/hr (110 gpm), heads to 52 m (170 ft), working pressures up to 10 bar / 145 psi and will operate in a temperature range of between -40 to 120°C (-40 to 250°F).

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.
The new HMD Kontro CSA (ASME) / CSI (ISO) sealless pump range, for chemical and industrial processes, is specifically designed for maximum part interchangeability, reduced inventory, ease of onsite servicing and future upgrade.
The new CSA / CSI range is quick to configure, easy to install and maintain a product line that has transformed how we now approach pump order fulfillment.
