HMD Kontro CS – Chemical Service Sealless Magnetic Drive Pumps

A unique sealless magnetic drive pump for heat transfer in hot oil systems.

Isolating the pump from the heat source has always been essential in a hot oil system –until now. Thanks to its unique torque ring, the CS pump from HMD Kontro requires no cooling fluids or heat exchangers during operation. The pump is totally self venting and the magnetic coupling is immersed in the hot oil. Not only that, but the torque ring design offers a built-in soft start for viscous liquids, and the energy created adds to the efficiency of the system.

Simple to operate and maintain, cost-effective to run and capable of operating up to 842°F without cooling –all this makes the Sundyne HMD Kontro CS pump the ideal choice.

  • Ideal for heat transfer liquids.
  • Sealless design –total product containment.
  • No product cooling required for temperatures up to 842°F.
  • One joint casing/containment shroud/shell.
  • Fully confined to eliminate ‘blowout’ risk.
  • Torque ring drive positively contributes to the efficiency of the hot oil system.
  • Built-in soft start feature.
  • Ideal for viscous start up.

The heavy duty line of chemical service sealless magnetic drive, end suction centrifugal pumps complies with specifications required by the oil, gas, petroleum and heavy chemical industries. The CS is typically used in toxic, aggressive, hot, crystallizing 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.

Standard materials of construction

  • Carbon Steel with Stainless Steel Option, complete with Carbon internal bearings.

Other material options are available on request

  • Duplex Stainless Steel
  • Alloy 20 and Alloy C276


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

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.
