The free-flow immersion pumps type FZ are equipped with a recessed impeller that makes this model ideal for pumping media with high solids loading or abrasive media such as lubricants and waste water. These pumps are particularly suitable for the use in systems in which centrifugal pumps with closed or semi-open impellers would not be acceptable.
