Reliability in use – for generations

Many years of experience and material expertise for critical applications

HERMETIC pumps have proven themselves in various reactor cooling water circuits as well as in secondary applications for boric acid dosing or decontamination. Our canned motor pumps are the only ones in Europe designed for motor temperatures up to 400 °C in primary and secondary circuits – without any additional motor cooling. Thanks to heat-resistant materials, precise welding processes, and decades of experience in handling contaminated, corrosive, and critical media, they guarantee maximum reliability under extreme conditions.

Primary and secondary circuits

Process regulation and dosing

Auxiliary circuits and safety circuits
