NEMO® BF Open Throat Progressing Cavity Pump with Auger

Solution for highly viscous and crumbly substances that do not tend to bridge-building

The NEMO® BF is used in all industrial markets to provide continuous, pressure-stable, gentle and low-pulsation handling with metering in proportion to rotation speed. This pump is used primarily for highly viscous, compacted and crumbly substances that do not have a tendency to bridge.

For optimal feed into the pumping elements, the pump housing is designed with an enlarged, rectangular hopper and conical force-feed chamber as well as a special coupling rod with a patented, horizontally positioned auger.
In block construction, this pump is particularly compact and economical.
