When failure isn’t an option, hermetic sealing becomes essential.
German pump manufacturer KSB has launched its EtaSeco type series—a new generation of canned motor pumps engineered for the most demanding applications where reliability, silence, and zero leakage are non-negotiable. With a service life exceeding 30 years, these pumps are built for the long haul.
Built for Mission-Critical Environments
The EtaSeco series targets applications where pump failure could mean catastrophic consequences:
- Data center cooling circuits – Keeping AI infrastructure running 24/7
- Transport engineering – Rail vehicles and modern wind power module cooling
- Environmental and industrial applications – Where leaks simply cannot happen
The EtaSeco series combines hermetic sealing with 30+ year service life
The Hermetic Advantage: No Seals, No Leaks, No Surprises
The EtaSeco’s completely encapsulated design eliminates shaft seals entirely—a game-changer for reliability. By removing the weakest link in conventional pump designs, KSB has significantly reduced the risk of unscheduled downtime while ensuring whisper-quiet operation.
