RKuV

Chemical centrifugal pump in plastic

The vertical centrifugal pump RKuV has been specially developed for pumping aggressive media that are contaminated with solids or that crystallize out. The series is insensitive to dry running and operation against closed slide valves, as there is no plain bearing in the pumped medium. The series is also available as lightweight design RKuVL.
