NEMO® B.Max® Mixing Pump with Conveying Screw
The NEMO® B.Max® is setting new standards with its maximum mixing and conveying capabilities for biosubstrates. It is the result of continued development work on the NETZSCH NEMO® Progressing Cavity Pump with hopper and conveying screw.
The pump housing has a large rectangular hopper and removable conical force-feed chamber, as well as a coupling rod with patented, horizontally positioned conveying screw, that guarantee optimal product feeding to the conveying elements. The positioning of the conveying supports on the hopper housing allows for maximum mixing of the substrate.
The NEMO® B.Max is particularly well-suited for the following substances:
- fermented NAWARO
- liquid manure
- process water
- ground biowaste and food waste
- preprocessed slaughterhouse waste
- cosubstrates
- concentrated substrates
- slop
Advantages of the NEMO® B.MaxTM hopper-Shaped Progressing Cavity Pump
- maximum homogenization of the substrate
- increased gas production
continuous low-pulsation conveyance independent of pressure and viscosity - high pressure capability
- robust drive seals
- low investment and operating costs
- high operating safety
- reinforced screw
Everything from a Single Supplier
To accommodate the various applications in your processes, it is now also possible to procure NEMO® Progressing Cavity Pumps together with the well-known NETZSCH TORNADO® Industrial Rotary Lobe Pumps.

NEMO® B.Max® Mixing Pump
1 Rotor
In wear- and corrosion-resistant designs.
2 Stator
Vulcanized into the tube with sealing on both sides in a variety of elastomers. Stator inlet with hopper-shaped opening for improved feed of the product into the conveying chamber.
3 Mixing and Conveying Screw
The reinforced and staggered spiral lobes of the mixing and conveying screw ensure maximum substance homogenization.
4 Shaft Seals
A single-acting, robust drive seal for the utmost in operating safety.
5 hopper Housing
Optimal positioning of the conveying supports allows for maximum mixing of the substrate. Removable conical force-feed chamber with an opening for inspection or feeding simplifies cleaning and maintenance and allows for additional product input. Hopper can be optionally coated to protect against abrasion and corrosion.
6 Block Construction
The drive is flanged directly to the lantern of the pump, resulting in compact dimensions, low total weight, constant axial heights irrespective of the construction type and size of the drive, and ease of maintenance and serviceability as well as high efficiency.
