For highly viscous, compacted and crumbly substances that have a tendency to bridge, the NEMO® BP Progressing Cavity Pump is your solution. Use the NEMO® BP in nearly any industrial market to provide continuous, pressure-stable, gentle and low-pulsation handling with metering in proportion to rotation speed. This model features the patented, horizontally positioned auger, the integrated bridge breaker and the enlarged rectangular hopper. The design of the coupling rod with auger and the conical force-feed chamber optimizes feed into the pumping elements. The bridge breaker prevents bridging and makes the mixing of aggregates possible. Custom hopper sizing is available. The block construction of the NEMO® BP with close coupling is particularly compact and economical.
