Save Space with GSPV


The vertically mounted GSPV pump provides all of the benefits of a magnetic drive sealless pump in a compact package that is particularly suitable for use where space is limited.

The GSPV meets all of the requirements of API 685 2nd edition, making it ideal for booster packages, pipeline injection, heavy duty chemical applications, monitoring and sampling packages, especially those where space is at a premium, such as offshore installations.

With a wide operating envelope of up to 40 Bar / 580 psi and flow rates up to 235 m³/hour /1250 gpm, the GSPV is available in nine hydraulics, which are split between two frame (magnetic coupling) sizes to suit different power requirements, with the option of ZeroLoss® shells in all configurations.

HMD also has a range of non-API vertical in-line units for use in various chemical and general industry applications. Further details can be seen at

A sister product, the LMV 801S, is also available, which is dimensionally interchangeable with the Sundyne LMV and VIP 801 pumps and will simply “drop-in” to existing pipework, making sealless upgrades possible without the need to modify pipe and foundation layout, to help meet increasingly stringent emissions regulations.

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.

Power Control Monitor – The Best Way To Protect Your Pump

Pump shutdowns can be costly, not only in repair costs but also from loss of product and revenue.  Power Monitoring is one of the best ways to protect your pump from not only shutdown, but also system upset damage and equipment failure.


What Is A Power Control Monitor?

The PCM is a device that senses true power input and so almost all pumping conditions that typically damage pumps can be detected quickly and ultimately avoided. It is installed in line with the motor driver of a pump or other rotating equipment.


What Does A Power Monitor Detect?

  • Dry-running
  • High Flow / End-of-Curve
  • Low Flow / Back-of-Curve
  • Jammed Impeller
  • Increased Viscosity / Precipitation
  • Severe Cavitation
  • Deadhead / Closed Discharged Valve
  • Decoupling (Magnetic Drive Pumps)

Advantages & Benefits of Power Monitoring

Power Monitoring has clear advantages over current or amperage monitoring since the input power varies linearly across the entire motor load range unlike current monitoring where the current is almost constant up to 50% of the motor load range, which makes it very difficult to detect changes below 50%.

The Power Control Monitor is therefore, an extremely reliable and accurate detector of system changes and as such most pumping condition changes will be seen in input power fluctuations. The benefits include:

  • Virtually eliminates pump damage due to system upsets
  • Significantly reduces spare parts costs
  • Reduces downtime
  • Reduces service costs
  • Eliminates extra component and installation costs
  • Isolates dangerous high voltage exposure for workers
  • Provides feedback for troubleshooting operational problems



A Power Control Monitor will certainly protect your rotating equipment investment, minimising costly pump shutdowns and reducing your operating costs.  For more information, please call us on +44 (0)1323 452154 or email;
