HMD Kontro HPGSP – High Pressure OH2 API 685 General Service Petroleum Sealless Magnetic Drive Pump

The HPGSP sealless magnetic drive pump from HMD Kontro is a high-pressure pump used in the oil & gas, petrochemical and chemical industries.

It provides reliable, safe processing and handling of hazardous and valuable hydrocarbons and chemicals.

It is a centreline mounted single stage pump built to API 685 specifications and suitable for heavy-duty pump applications. The pumps are extremely versatile and safe and are capable of handling system pressures of up to 2680 psi and higher if required, depending upon temperature extremes. The design has support brackets on the casing to minimise vibration and allow for thermal expansion.

HMD Kontro HPGSP pumps are available in eleven hydraulic sizes and two basic frame sizes to meet power requirements. Standard materials of construction are A-8 and S-5 with silicon carbide bearings with other variations available on request.

The pumps comply with all specifications required by the oil & gas, petroleum and heavy chemical industries and are typically used in toxic, aggressive, hot, crystallising and high value processes.

Our pumps combine cutting-edge technology with over seventy years of expertise and experience to give you complete piece of mind.

Product Security – Magnetic drive sealless pumps are the safest and most robust means for liquid transfer. By eliminating the seal, the primary opportunities for leaks associated with traditional sealed pumps are completely removed.

Efficiency – By improving performance and reducing maintenance calls, sealless magnetic drive pumps can dramatically lower downtime and lost production. In sum, this equates to maximised efficiency that can be seen on your bottom line.

Reliability – Sealless magnetic drive pumps have proven their reliability in even the most severe climate conditions, from the frozen tundra of Siberia to the deserts of the Middle East and the humid climes of Louisiana’s refineries. In fact, there are  HMD Kontro pumps that have been in operation for over 30 years and are still running today.

Safety – HMD Kontro sealless magnetic drive pumps are manufactured to conform to international design and safety standards, including ATEX, ISO, API and ANSI requirements.  Plus, with no mechanical seals to leak hazardous chemicals, these pumps offer a clear choice for process industry professionals who regularly deal with volatile or high value materials.

Cost-effective – Sealless magnetic drive pumps require less monitoring and maintenance than traditional sealed designs, equating to substantial savings over the life of the pump.

Service – Global service centres keep HMD Kontro sealless magnetic drive pumps operating with peak performance.  Standard pumps and parts are available from the factory and in the field.

Installed in the Motor Control Centre (MCC), a power monitor measures the power required to operate the pump.  By setting High and Low trip points, the power monitor is the perfect solution for protecting your pump from:

  • Dry running
  • Low flow operation
  • High flow operation
  • Severe cavitation
  • Magnet decoupling

A gas detection system designed to bolster the reliability and eliminate dry-running of HMD Kontro API-685 sealless magnetic drive pumps. This warning system mitigates costly pump component replacements and downtime that can result from dry running, entrainment or cavitation.

The VapourView® is powered by an industry standard 24 VDC supply and returns a 4-20 mA signal suitable for monitoring using a distributed control system (DCS). It features both light emitting diode (LED) and liquid crystal displays (LCD) to provide information on process fluid conditions inside of the pump to process engineers.

The VapourView® has been performance tested and is compliant with explosive atmosphere and electro-magnetic compatibility requirements. The VapourView® non-intrusive gas-in-liquid detector can be easily retrofitted into any HMD Kontro API 685 pump and will operate at temperatures between -40 and +350 degrees F (-40 and +180 degrees C).

HMD Kontro sealless magnetic drive pumps are available with secondary control devices to restrict any leaks. Mechanical devices are fitted to the drive shaft assembly and are activated in the unlikely event of containment shell failure. The pump coupling housing is also fitted with gaskets to eliminate any leaks across the joining faces.

All HMD Kontro pumps, as standard, can handle up to 5% hard solids and 150 microns diameter. The solid size can increase to 8% solids and 250 microns by fitting a self-cleaning in line filter.

For larger solids, HMD Kontro can provide pumps with a clean flush system or filter built into the flush pipework.
