Type FZ

Torque flow pumps - Type FZ

The free-flow immersion pumps type FZ are equipped with a recessed impeller that makes this model ideal for pumping heavily polluted or abrasive fluids 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.
