NEMO® BF Open Hopper Pumps

The NEMO® BF open hopper pump 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.

Compact Progressive Cavity Pump Design

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.

NEMO® BF Open Hopper Progressing Cavity Pumps offer you:

  • gentle product handling
  • pump connections in accordance with national and international standards, as well as in specially designed models
  • easy serviceability

The NETZSCH NEMO® BF Open Hopper Pump works based on the progressive cavity principle, where a rotating eccentric screw inside a stator creates a continuous flow in the pump chamber. The open hopper design allows for easy feeding of the product into the pump and ensures efficient conveying of even highly viscous, abrasive, or shear-sensitive materials. The pump’s unique geometry also enables gentle pumping action, minimizing product damage and ensuring consistent performance over its operational life.

The NETZSCH NEMO® BF Open Hopper Pump has several key features and benefits:

  • Gentle pumping: The pump’s open hopper design ensures gentle handling of shear-sensitive and viscous fluids, reducing the risk of product damage.
  • Solids handling: The pump is capable of handling high-solid content materials up to 12% by volume, making it suitable for a wide range of applications.
  • Low pulsation: The pump’s progressive cavity design provides low pulsation flow, resulting in a smooth and consistent flow rate.
  • Easy maintenance: The pump’s modular design allows for easy maintenance and replacement of individual components, reducing downtime and maintenance costs.
  • Versatility: The pump can handle a wide range of fluids, including abrasive, corrosive, and highly viscous fluids, making it suitable for a variety of industries such as food and beverage, chemical, and wastewater treatment.
