Canned motor pumps with explosion protection for potentially explosive atmospheres
Canned motor pumps with explosion protection are used wherever flammable or potentially explosive media need to be pumped safely – for example, in the chemical, petrochemical or energy industries. They are suitable for numerous standard applications where leak-tightness, operational safety and availability are crucial.
Thanks to their modular design, canned motor pumps can be flexibly configured and adapted to the specific process requirements. A range of different models allows for a precisely tailored selection depending on the fluid, temperature range and area of application – ensuring maximum safety and efficiency during operation.

Type / Design
Single-stage standard chemical pump in accordance with EN 22858 / ISO 2858 with canned motor drive
The CN series is the standard version of HERMETIC canned motor pumps. It is suitable for pumping common liquids with a sufficient margin above the vapour pressure (non-boiling media).
Type CNF
Type / Design
Single-stage standard chemical pump in accordance with EN 22858 / ISO 2858 with canned motor drive
The CNF series is designed for liquefied gases, boiling media and condensates. With an integrated auxiliary impeller and internal liquid recirculation, it is suitable for pumping liquids at pressures close to their vapour pressure.
