Safety First as Office Staff are Back in the Building!

Having operated throughout the lockdown period, our EHS Manager, David Watson, has been busy ensuring that the working environment at HMD Kontro is as safe as possible for the phased return of office staff to our Eastbourne headquarters. It’s definitely safety first as office staff come back to work.

All of the teams, including the manufacturing crews, are in their own ‘work bubbles’ and have a shift rotation system for the canteen including breaks and mealtimes. A new canteen, so that office and manufacturing staff have their own dedicated facilities is now fully operational.

Staff safety measures in place at HMD Kontro now include:

  • COVID-19 signage according to directives
  • Hand sanitiser stations at all entrances
  • Screens installed between desks and work stations
  • Enhanced cleaning programmes
  • ‘Clean as you go’ for all multiple use surfaces
  • 2 metre social distancing wherever possible
  • 1 way system in the canteen and other areas
  • Grabber for opening and closing doors

Safety notices are refreshed frequently

Safety signage is frequently being changed and updated with the EHS department working closely within PHE directives. Signage is continually being refreshed with new information so that staff members are constantly being reminded of the safety directives in place, which is considered vital so that staff do not become complacent.

‘Clean As You Go’ for all multiple use surfaces

 Areas with a high footfall such as the photocopier and water stations have cleaning materials adjacent so that they can be cleaned before and after use. An enhanced cleaning programme has also been implemented whereby there are two more thorough cleaning practices for multiple use areas including the canteen.

 The Raptor Claw – For safe door opening and closing

 As an added extra action, all staff have been equipped with a unique grabber, which conveniently attaches to their work lanyards and can be used to open doors and switch lights on and off. It’s being affectionately labelled as the ‘Raptor Claw’ by the staff, but it means door handles etc. do not have to be touched, thereby helping to prevent the spread of infection.

Gradual return of staff to the office

The phased return, with most staff expected to be back working in the office by mid October, begins with an orientation session with the EHS department. This goes through actions implemented for the team’s safety, including the rota system for the canteen, the one-way system and basic hygiene including frequent hand washing and sanitising.

GSPVS – Reaching Parts Other Magnetic Drive Pumps Cannot!

GSPVS Pump and Cutaway diagram


Designed for use on tank farms for fuel transfer, as well as in tank applications at oil and gas refineries, chemical and petrochemical processing plants etc, the GSPVS pump meets the requirements of API 685 (as applicable to this style of pump) and is fully ATEX compliant.

The GSPVS pump comes in a compact package with all the benefits of a magnetic drive pump

The vertically mounted GSPVS pump provides all of the benefits of a magnetic drive pump in a compact package, using fewer parts with no seal systems for reduced cost operation. Composed of modules which can be joined to reach a total assembly length up to five metres, the GSPVS is mounted on a base available to ANSI B16.5 or to customer specific requirements, including lifting points as standard. The modular construction uses a flexible jaw coupling to join drive shafts and to absorb misalignment, decreasing vibration and increasing life expectancy.

Maximised seal and lubrication life

Greased for life ball bearings are used along the column, removing the need for lubricating or cooling the intermediate sleeve bearings using system fluid. The use of labyrinth bearing seals and a suction strainer avoids external contamination to maximise seal and lubrication life.

Looking after the safety of personnel

The GSPVS utilises over thirty years’ experience in API applications and over a seventy year heritage in magnetic drive technology at HMD Kontro. With stricter demands for the safety and welfare of both personnel and the environment being imposed, sealless pumps are playing an increasingly important role.

Think Sealless – Why buy a pump that leaks?

Think Sealless represents HMD Kontro’s passion to inform the process industry about this engineering revolution and the benefits of magnetic drive pumps over traditional sealed pumps, including those with complex and costly seal support systems.

Why buy a pump that leaks? How long is it since you evaluated the considerable cost savings and safety benefits of a sealless, magnetic drive pump against the traditional type of pump, which depends upon seals, with their inherent risk of leaks, to maintain integrity and contain your product?  If it is some while, you may be surprised at how often sealless is now the solution, and how making a step change in your process technology could benefit your business.

Sealless pumps are essentially conventional centrifugal pumps without packed glands or seals. The seal is replaced by a static containment shell or shroud to form a completely sealed liquid end or pressure boundary.

Sealless pumps are easier to maintain, have fewer working parts, no potential leak paths and no support systems to design, install and maintain. Maintenance is simple, and the life cost is significantly lower than that of a mechanical sealed pump.

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

When it comes to applications in the chemical, oil, petroleum, gas production, pharmaceutical and general process industries that involve toxic, fine, corrosive and aggressive liquids, our sealless magnetic drive pumps deliver the rock solid, dependable, and reliable performance that engineers demand and that industrial regulations require.

50 & 30 Year Very Long Service Awards at HMD Kontro

We are extremely proud of our team and we are always keen to recognise and congratulate any of our staff who reach long service milestones. This month Richard Baxter and Mick McVay received their very impressive Long Service Recognition certificates for having worked 50 and 30 years respectively at HMD Kontro.

Richard joined us 50 years ago on 20th March 1970 as a Trainee Apprentice and, at the time earned the princely sum of 3 shillings and 10 pennies (19 pence) per hour and 15 days annual holiday. The UK was very different back then with minimal technology, children playing in the streets and the fashion was flared trousers and platform shoes.

At the age of 17, Richard was keen to go to college part time and there he completed his C&G in Mechanical Engineering. Richard still enjoys his job at HMD Kontro, but has reduced to 4 days per week, so that he can spend more time with his wife, Lynne.

Mick joined on 26th March 1990 as a Centre Lathe Turner with a starting salary of £9,500 and has steadily progressed his career with HMD Kontro. Born a US citizen, Mick came to the UK in 1968 in his teenage years and attended school in Wiltshire. Mick lives in Eastbourne and is married to Jane and has 2 daughters. He passed the stringent, “Life in the UK” test and became a Brit in 2017 with HMD honoured to support him.

Both Richard and Mick received their Long Service Recognition certificates as well as bubbly, cake and a beautiful bouquet for their wives.  We thank them for their dedicated service to HMD Kontro.

Sundyne LMV 801 Pump Upgrade

Sealed 2 Sealless to Meet Emissions Regulations

With ever more stringent emissions regulations, including those from such bodies as the EPA (United States Environmental Protection Agency) a simple way to meet these increasingly difficult requirements, while also improving worker and site safety, is to replace existing mechanically sealed pumps and systems with leak-free- sealless magnetic drive pumps.  For vertical pump applications, including those to API 685, the LMV 801S provides an excellent alternative, which can often easily be installed into existing pipework.

Sealless pumps completely contain the liquid with no opportunity for leaks or emissions.  Maintenance is minimised and uptime is maximised plus there are no seals to replace and/or seal systems to replenish.  For particularly hazardous liquids, such as HF alkalis, secondary control and containment options can be incorporated and alternative materials used in the pump’s construction.

Convert Existing LMV 801 Pumps to Sealless Alternative

The LMV801S is dimensionally interchangeable with the Sundyne LMV 801 mechanical sealed pumps (which cannot be upgraded due to space constraints that prevent the use of an alternative cartridge seal).  It can be easily connected to existing pipework and foundations making an upgrade possible without the need for modification.  The LMV801S can also be used to upgrade from VIP 801 canned motor pumps.

A plug-in version of the pump is also available enabling the existing LMV 801 casing and diffuser to be left in the pipeline whilst replacing the mechanical seal drive with a sealless drive end.  The LMV 801S is also a popular choice to replace other existing vertical sealed pumps and canned motor pumps.

The Sealless API Pump Solution

The HMD Kontro GSP heavy-duty API magnetic drive, end suction centrifugal pumps comply with specifications required by the oil, gas, petroleum and heavy chemical industries. Typically, the GSP range is used in toxic, aggressive, hot, crystallising and high value processes.

As with all HMD Kontro sealless pumps, the GSP range eliminate leaks for enhanced safety and environmental protection plus reduces servicing, maintenance and spare parts inventory to maximise process uptime, with no seals or seal support systems resulting in substantial cost savings over sealed alternatives.

The core GSP pump line consists of sealless horizontally mounted pumps covering a comprehensive hydraulic range split across four frame sizes with a number of synchronous magnet drives rated to match prime mover performance.  A corresponding range of torque ring drives is available for high temperature operation and recent developments include:


  • High Pressure – HPGSPCapable of easily handling system pressures up to 185 bar and higher dependent upon temperature extremes.


  • Vertical – GSPV:  Vertically mounted pumps providing all the benefits of a sealless pump in a compact package, requiring minimal floor space.


  •  Low Flow – GSPLF:  A low flow sealless pump with a relatively high head capability, combining Sundyne Barske Wheel hydraulics with the HMD Kontro magnetic drive.


  • Multi-Stage – GSPXAvailable in two or three stages with two diffuser based hydraulic options, to produce higher differential pressures.


  • Vertical Low Flow – LMV 801S:  A vertical variation of the GSPLF, the LMV 801S is conveniently dimensionally interchangeable with the Sundyne LMV 801 mechanical seal pump.

CS Magnetic Torque Ring Upgrade


The upgrade of the outer magnet ring on the CS pump range offers significant advances in magnetic coupling robustness leading to increased MTBF (mean time between failure), reduced downtime / increased uptime and increased operational efficiency.


The retro-fittable outer magnet ring (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.


This upgrade is straightforward as no specialist tools are required and is recommended as the current magnets used in the CS pump are becoming obsolete and so no longer available as spare parts.


With increased safety due to there no longer being a remote possibility for the magnets to come into contact with the containment shell, this upgrade is recommended for all current CS pumps.


Download the Torque Ring Upgrade Leaflet for further information or contact our team to discuss how you can upgrade.
