NEMO® B.Max Mixing Pump in Block Design
Solution for mixing and conveying in biogas technology and environmental technology
The NEMO® B.Max in block design with directly flanged drive from NETZSCH sets new standards in biogas and environmental technology through maximum mixing and conveyance of the media. It is the result of continuous development of the NEMO® helical rotor pump with feed hopper and feeding screw.
Thanks to its pump housing with a large, rectangular feed hopper and removable, conically shaped stuffing chamber, as well as a coupling rod with a patented, position-optimized conveying screw, the progressing cavity pump guarantees optimal product feed into the conveying elements regardless of pressure and viscosity.
B.Max pump: Maximum mixing of substrates
The position-optimized tangential inlet on the hopper housing facilitates maximum mixing of the substrates. The B.Max is particularly suitable for continuous and low-pulsation conveying of fermented renewable raw materials, liquid manure, process water, ground biowaste, food waste, pre-processed slaughterhouse waste, concentrated substrates, thickened substrate and slop.

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.
