The MF is a compact submersible pump with large solids passage for reliable and effective dewatering of buildings and sites.



The Sulzer MF 154-804 features a vortex impeller as well as a large free passage for excellent solids handling. This compact, robust pump features a water tight, fully flood proof cast iron motor and a hydraulics section.

All units are available in either automatic or manual versions, and have the capacity to handle grey water with temperatures up to 40°C (60°C intermittent duty). All MF pumps are fitted with chokeless impellers to enable the handling of large sphere-size solids up to 65 mm in diameter. Larger flow rate units are available on request.

Both single and three phase units have in-built overload protection and are fitted with 10 m motor cables.

Pumps can be supplied in either free-standing configuration or on auto-coupling pedestals mounted with guide rails.
