PromoTec is a Dutch based company, located in Hilversum, supplying and servicing sealless pumps for Hydrogen carriers and many other applications. Already since the early 1980s, PromoTec has focused on sealless industrial pumps. Like Greenpumps magnetically driven pumps and Wanner Hydra-Cell sealless diaphragm pumps. Sealless means there is no mechanical seal in the pump. Due to the absence of a seal, the pumps offer complete containment of the medium. This makes the pumps completely leak- and emission-free. A packing can leak and that is unacceptable in the field in which these pumps are used.
Sealless pumps require less maintenance, since there are no mechanical seals to replace. Less maintenance means less downtime. Leaks are disastrous for the environment and also no longer acceptable due to increasingly strict regulations.
The sealless centrifugal and displacement pumps are more expensive, but they also last much longer and rarely or never cause problems. As a result, the Life Cycle Costs are actually lower than with traditional seal pumps.
PromoTec offers technical support and pumps to many innovative companies in the new energy sector, for Hydrogen carriers like formic acid, ultra-pure water, electrolytes, hydrocarbons, hydrozine and sulfuric acid. Handling a variety of high pressures, relatively high temperatures, low capacities, gas inclusions, Atex: all leak- and emission free.
