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.
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.
We couldn’t let Stuart Pugh go without a bit of a send-off. He has after all been with HMD Kontro for 36 years and certainly deserves his retirement.
On a recent Friday evening, Stuart thought he was just going to the Eastbourne United Football Club for a couple of beers with some close colleagues. But in true HMD Kontro style, we had other plans!
We wanted to give him a great send-off. The staff were informed of the event and they didn’t disappoint and came along to raise a glass to a well-liked colleague. It certainly was a big surprise for Stuart, which he really enjoyed.
Over the years, Stuart worked at the Unigate Dairy as a Maintenance Engineer before joining us as a Centre Lathe Turner in 1985. He was only with us for sixteen months before joining a rival pump manufacturer. That didn’t last long and Stuart was back with HMD Kontro in 1987 and has stayed ever since.
We would like to wish Stuart a long and happy retirement. We understand he is looking forward to spending more time with his family and beloved motorbikes.
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.
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.
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.
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.
With lockdown restrictions easing, our race driver team member, Neil Jessop, has at last now been out racing once again, although at the moment without spectators. In his heavily modified 1978 Mark 2 Ford Escort, sponsored by HMD Kontro, Neil has achieved some great results, despite a few mechanical issues.
9 May Donington – Winner of Class B in both Race 1 and Race 2
With thirty-seven cars on the grid, Neil won his class in both races and also finished ninth and tenth overall respectively, beating many cars from higher classes. He also set the lap record in his class of 1:17:486.
13 June Mallory Park – Third in Class B in Race 2
This was an amazing result, as Neil had to start Race 2 from the back of the grid after an electrical issue earlier meant no result in Race 1. With skilful driving, he made his way through to eleventh at the finishing flag, giving him third in Class B. He also recorded the second-fastest lap of 51.773 seconds.
See the full video from Race 2 at Donington over on YouTube (it is not for the faint-hearted).
The series continues with races in July at Anglesey and Cadwell Park and then it’s on to Oulton Park and Brands Hatch with the last race at Snetterton in October. We will keep you updated with Neil’s progress!
Preventing HF Acid Harming Employee Health and the Environment.
Operators of the Hydrofluoric (HF) acid alkylation process will know all too well that the pumping of HF acid is an application that presents a set of totally unique challenges.
Working in collaboration with UOP (Honeywell), we have been able to develop proven sealless pumps exclusively for use in HF alkylation units. An innovative approach using alternative materials and a new method of NDE (Non-Destructive Examination) specifically for pumps entering the HF Alkylation process.
Above: Short video introducing the new HF alkylation units.
Due to the hazardous nature of HF acid in the alkylation process, it must be treated with the utmost care and so HF alkylation units demand a fluid handling solution of the very highest standard. This makes magnetic drive pumps eminently suitable. By comparison, pumps featuring failure-prone mechanical seals can leak harmful process fluids, negatively impacting employee health, the environment and productivity. HMD Kontro sealless pumps offer the highest level of safety and reliability with absolutely no leakages, for complete fluid containment.
The Benefits of HMD Kontro Pumps for HF Acid
HMD Kontro has developed a pump design specifically for the HF alkylation process that contains key features and includes an identified core scope of equipment. This package must be supplied, as a minimum, on all pumps destined for an HF alkylation unit and contains the following benefits:
In chemical processing, with increasing environmental concerns and a strengthening of international safety standards, choosing the right pumps is essential when it comes to protecting plants and people against potentially dangerous leaks and avoiding processing downtime.
In a new article, published in Pump Engineer, Darren Martin, our Global Product Line Manager, looks at the latest developments in magnetic drive sealless pumps and how they protect the environment and ensure operator safety.
The article charts the recent evolution of sealless pumps, illustrating how the latest new technologies and materials have been applied to further advance and perfect modern magnetic drive sealless pumps, such as HMD Kontro’s CSA/CSI range. Not only maintaining their highly safe operation, but also making them an attractive proposition in terms of product life cycle time and costs savings, offering greater flexibility and ease of maintenance.

Did you know that the home of HMD Kontro in Eastbourne is not just the sunniest place in the UK, but it is also a thriving pump cluster?
Home to not only HMD Kontro, over the years a good number of other pump manufacturers have chosen Eastbourne as the place to set-up shop. There is a reason for this, so let us travel back in time by 75 years to 1946, the year that brothers Geoffrey and Charles Howard founded Hydraulic & Mechanical Developments Ltd, with the first sealless magnetic drive pumps being pioneered the following year in 1947. This of course became HMD Kontro Sealless Pumps, a division of Sundyne, that we are today.
The Howard brothers, as brothers often do, had a falling out and the two went their separate ways. This other company, which became known as ‘APV Howard’ and then onto ‘APV Industrial Pumps’ began operations and that too was started in Eastbourne. Both of the brothers were pioneers of their time and this led to the supply chain around the town building up, which in time put Eastbourne on the pump manufacturing map.
Additional pump companies then chose to relocate or begin operations in Eastbourne as that is where the expertise, experience and supply chains were based. This includes ‘Johnson Pumps’ who are also still operating in Eastbourne today and just a mere stone’s throw away from the HMD Kontro units.
It is because of the Howard brothers and the founding of HMD Kontro back in 1946 that has led to Eastbourne being what is often referred to as a ‘pump cluster’. The decision 75 years ago has left a lasting mark on the town and its rewards are still being reaped today. HMD Kontro has continued to evolve and leads the way in the pump industry. Particularly in magnetic drive 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.
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!

If you have a particular liquid that you wish to pump, then please contact us for advice. There is a very good chance that we have worked with this product in the past and can advise on the most appropriate pump for your application.
HMD Kontro sealless pumps can be manufactured to relevant specifications such as ASME, ISO and API. To check the applications and operating parameters of our magnetic drive pumps, please see the Think Sealless Select page.
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).

HMD Kontro is delighted to be sponsoring Neil Jessop in this season’s Modified Ford Series. Neil was ready and almost on the starting grid for last season’s series when you could say the pandemic literally threw a ‘spanner into the works’. Not surprisingly, there was no racing last year, but Neil is more hopeful that there will be meetings this year as the UK begins to open up. He is prepared and raring to go and race in the Modified Ford Series in his Ford Escort sporting the HMD Kontro logo and brand.
HMD Kontro Branding Doing The Circuit
The series was established to provide ‘the place to race’ for the huge variation of modified Ford (production) cars that have been developed over the last fifty years. The classic Ford cars which must be pre-2010 race in various categories determined by their engine size. Neil and his Ford Escort will be racing in the 2.0 Litre class B, which also features Ford Sierras and Capris. The shiny black Escort is a 1978 Mark 2 classic car. However, Neil points out that all that remains of the original car is the shell as it has been completely refitted with modern racing components. The shiny black Ford Escort certainly stands out with its new livery including red and yellow stripes and orange HMD Kontro branding.
Modified Ford Series
The Modified Ford Series will comprise eight races at famous racetracks including Lydden Hill in Kent, Donnington Park and Mallory Park, both in Leicestershire, the Cadwell Park circuit in Lincolnshire referred to as the ‘Mini Nurburgring’ and Brands Hatch. Neil intends to go to as many as he can although distance sometimes dictates that this is not possible. Although the cars do not have speedometers, they can reach speeds of up to 140mph. Races involve fifteen minutes of qualifying to establish a grid position followed by two fifteen-minute races.
A racing love affair that started at Arlington race track
Neil Jessop joined HMD Kontro in 1998, just over twenty-two years ago and today he runs tests on the sealless pumps once they have been produced. Coincidentally, his love affair with cars and racing started at this time. It was at Arlington race track near Eastbourne where he first started racing stock cars and then went on to hot rods, racing on different tracks in the south east. A progression to circuit racing from the oval racetrack followed some ten years later. It was then that Neil started building his own cars including a Silhouette, based on a Peugeot 206, which is all pretty technical stuff involving a tubular chassis with fibreglass panels. However, for a pump test engineer, it’s just what comes naturally!
Opportunities with HMD Kontro
HMD Kontro is delighted to sponsor Neil in the forthcoming season of racing and demonstrates another way of how we help our staff. If you are looking to work for a progressive company that manufactures sealless pumps, please see www.hmdkontro.com/recruitment.
