NEMO® BF Hopper Shaped Pump With aBP-Module®
The solution for highly viscous and crumbly substances that tend to bridge
The NEMO® BF hopper shaped progressing cavity pump with aBP-Module® to prevent bridging is used in all branches of industry for continuous, pressure-stable, gentle and low-pulsation conveyance as well as dosing in proportion to speed, especially for highly viscous, compacted and crumbly media.
For optimum product feed into the conveying elements, the pump housing is designed with an enlarged, rectangular feed hopper and conical force-feed chamber as well as a special coupling rod with patented, positioned conveying screw. The additionally attached aBP-Module® - asynchronous Bridge Preventing - consists of a top shaft with two internal spoke wheels.
NEMO® BF hopper shaped pump prevents bridging
These create “moving shaft walls” which exert a shearing effect on the medium. This reliably prevents bridge formation in the pump shaft. This also ensures the smooth conveying of solid-loaden, shear-sensitive, abrasive, adhesive, thixotropic or dilatant as well as lubricating and non-lubricating materials that have a tendency to bridge. The NEMO® is particularly compact and economical in block construction with flanged drive.

FAQ progressing cavity pumps
Progressing cavity pumps are particularly suitable for pumping highly viscous, abrasive, solid-laden or shear-sensitive media. Typical applications include the chemical, food, environmental, paper and building materials industries, as well as the oil and gas sector.
NEMO® progressing cavity pumps from NETZSCH Pumps & Systems are characterised by gentle, low-pulsation pumping, high dosing accuracy and a wide range of applications. They enable a constant delivery rate even with changing pressures and media compositions.
Progressing cavity pumps can be used to convey low-viscosity to highly viscous media, including slurries, suspensions, pastes, media with a high solids content, and sensitive or gas-laden liquids.
Yes, progressing-cavity pumps are self-priming and exhibit excellent suction performance. This makes them ideal for applications with changing fill levels or difficult suction conditions.
Maintenance requirements are low and predictable. Wear parts such as the rotor and stator can be easily replaced. Maintenance-friendly designs enable short downtimes and high plant availability.
The service life depends on factors such as the medium, speed, pressure and choice of materials. Professional design and the use of original spare parts ensure a long service life and economical operation.
All relevant original spare parts are available for progressing cavity pumps from NETZSCH Pumps & Systems, including rotors, stators, seals, joint parts and other wear-related components. The spare parts are precisely matched to the pump design and ensure high operational reliability.
The correct spare part can be identified by the machine number, serial number, or item number. Spare parts lists, sectional drawings and the operating and maintenance instructions also provide support. Alternatively, the NETZSCH Pumps & Systems service team can provide expert advice on selecting the right original spare part.
The experts at NETZSCH Pumps & Systems will assist you in the design, selection and integration of the right progressing cavity pump – tailored to your specific pumping tasks and process requirements.
