Think Sealless Smart

Magnetic drive sealless pumps from HMD Kontro have many key design features for increased reliability, cost effectiveness, enhanced safety and environmental friendliness.

Why sealless pumps are the smart choice

The smart choice is usually to say yes, however, our customers seem to like it when we say no:

HMD Kontro pumps are built to last and we have many examples of extended pump life in our seventy year history, we have more experience than any other manufacturer. In many installations HMD Kontro have run without maintenance for ten years and often more.

In most HMD Kontro pumps we use silicon carbide bearings, a material so hard that under normal process and conditions it will not wear for many years. When you add permanent samarium cobalt magnets and the unique way we engineer our pumps, this results in a very long service life with minimal maintenance and cost. Although it is difficult to give a MTBF (mean time between failure) because of the wide variety of applications they have, on clean liquid it can be in the region of 10 years or more.
