NEMO® Progressing Cavity Pumps

NEMO® B.Max Progressing Cavity Pump

Ideal Pump Solution for Mixing and Conveying of substrates in Biogas Production

The NEMO® B.Max Progressing Cavity Pump Model is the result of the continuous development of the NEMO® progressing cavity pump in order to suit specific application needs. The pump is designed with a hopper at suction and a feeding screw along with an inlet port for substrates, designed for homogenous mixing and conveying of substrates in biogas production. Their capability of homogenous mixing and efficient conveyance of the various raw substrates to the biogas plant ensures higher levels of gas yields. This Pump in Block Design with a directly flanged drive from NETZSCH for a short foot print. 

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. 

NEMO® B.Max Progressing Cavity Pump: Maximum mixing of substrates 

The various substrates that the NEMO® B.Max Progressing Cavity Pump convey include Agro waste, food waste, press mud, municipal solid waste, and pre-processed slaughterhouse waste. Substrate feeding in biogas production often pumps choking and thereby high service and maintenance requirements.  The NEMO® B.Max Progressing cavity pump comes with optimally positioned liquid feeding ports and an excellent screw design for the ideal mixing and conveying of dry substrates.

NEMO® B.Max Mixing Pump Construction

Innovative Design for Optimal Performance

The NEMO® B.Max progressing cavity pump comprises a pump housing with a large, rectangular feed hopper and a conically-shaped stuffing chamber for continuous feeding of the homogenous slurry into the pumping elements.

The coupling rod features a patented, position-optimized conveying screw. This ensures optimal mixing and product feed into the conveying elements, maintaining efficiency across varying pressures and viscosities. The conveying screw is in two parts which enables to replace the part on the pressure side, which is exposed to stress. This saves costs and facilitates easy service.  

The pump design has metal protection sleeves and joints that provide further safeguards. The reinforced and staggered spiral lobes of the conveying screw ensure maximum homogenous mixing and conveying of the substrates. The optimally positioned feeding screw is connected to the conveying chamber contra to the direction of conveyance, guarantees an optimum feed of liquid to the conveying chamber, which ensures maximum mixing of substrates.

The large, easily accessible inspection openings on the conveying chamber ensures easy cleaning and maintenance.
