Biogas / Agriculture

NETZSCH Mohnopumpen GmbH – the globally operating producer of NEMO® Progressing Cavity Pumps, TORNADO® Rotary Lobe Pumps and NEMO® Grinding Systems – is your first-rate specialist in biogas technology. A combination of high operating safety with cost effectiveness is of foremost importance in this field – and NETZSCH is your most competent and dependable partner for this interplay.
The “energy” for biogas comes from NAWAROs or organic waste material which is largely converted into methane with the help of diligent bacteria under the exclusion of air. At the beginning of the process, the enzymes are charged with the substrates. At a dry matter content of approx. 5-15%, the fermentation process consists of four biological phases: the hydrolysis phase, acidification phase, acetogenic phase and methanogenic phase. The conversion into predominantly biogas, carbon dioxide and water vapor takes place at a temperature of about 40°C. NETZSCH provides the appropriate importation technology for the stable operation of these processes along with pumping and grinding technology designed to handle a great variety of substances.

Mixing Pump

The NEMO® B.Max sets new standards with its top-of-the-line mixing and conveyance capabilities for your bio-substrate. It is the result of continuous development work on the NEMO® Progressing Cavity Pump with hopper and conveying screw.

NEMO® BY Progressing Cavity Pump

NEMO® BY Progressing Cavity Pumps can be used in any area of industry where a great variety of different substances must be pumped or very precisely dosed.

TORNADO® Rotary Lobe Pump

A TORNADO® rotary lobe pump fastened onto a mobile base – this is the NETZSCH TORNADO® Mobile. The concept of mounting the equipment onto a car or truck trailer makes it possible to pump large quantities of fluids with solid content, wastewater and slurries at the most unusual of sites.

NEMO® Grinding Systems

NETZSCH grinding systems can be used wherever it is essential that solid matter in fluids be broken down reliably to ensure the prevention of pipe clogging and damage to downstream equipment. The NETZSCH M-Ovas® and the NETZSCH Twin Shaft Macerator enable optimal and efficient grinding of solids in the most varied of applications.

NEMO® Immersible Pumps NEMO® semi-submersible pumps are used for emptying barrels, containers, tanks, clarifi ers, pits, etc. They are also used where space is limited and when cavitation may be a danger or where low NPSH is available. Furthermore the pumps are suitable for emptying barrels containing materials harmful to water and the environment where emptying through a connection at the bottom of the barrel is not permitted. Performance Capacities up to 140 m3/h (620 gpm). Pressures up to 24 bar (340 psi). Depending on the application a number of designs/immersion variations are available. The immersion depth is adjusted as required by the application. Description Compact design with directly flanged drive. Four rotor/stator geometries for optimal performance. Immersion depth up to 10 m. The length of the immersed tube can be modified by using an extended pump housing or anadditional suction pipe or a combination of both.

NEMO® Immersible Pump BT with integral Mounting Plate This pump is used in closed pits, tanks and containers where there is the possibility to vertically flange mount the pump to the tank lid. Depending on pump size, speed and immersion depth up to 10 m, an additional support guide is available to secure the pump to the bottom or to the wall near the bottom. Removal of the pump from a full tank is possible because the guide units are self-centering and secure the pump suction without fixings. The pump with discharge connection below the mounting position the discharge connection of the pump is below the tank lid. The product is either piped to the outside vertically through the lid via a 90 ° elbow or horizontally through the tank wall. This minimize the dead space in the pump housing thus reducing the overall height of the pump above the tank lid. This version is normally used where there is only limited space available.		NEMO® Immersible Pump BT with Suspension Bracket This pump is used for emptying open barrels and containers. It is equipped with a suspension bow for crane suspension. Immersion depth up to 3 m.

NETZSCH in the Oilfield General Features of NETZSCH Oilfield Pumps and Systems NETZSCH offers the complete progressing cavity pump range for up and downstream production complete with the necessary equipment such as pump, drive head and motor, control cabinets, rods and other accessories. The range of pumps includes downhole pumps, submersible downhole pumps, transfer pumps, multi-phase pumps and injection pumps. These pump systems are used for a continuous, pressure stable, non-emulsifying, almost pulsation-free conveyance of waste water and crude oil. Wide Range of Applications The pumps are mainly used for fluids with the following properties: High solid content (up to 30 % sand) and also free of solids Low to high viscosities Abrasive High content of gas High content of water High fluid and environmental temperature

Upstream Submersible Downhole Pumps Above all, this system is suitable for deep installation including oglegged and horizontal bore holes. A remarkable feature of this conveying system is that no rods are required and, thus, wear on the tubing is dramatically reduced.

Consequently, operational and maintenance costs are low as well as is the initial investment cost. When treating crude oil in oil field processing, NETZSCH pumps are used for procedures such as separation, H2S and sulphur reduction, and gas purification or filtration, to name but a few. Injection Pumps NETZSCH high-pressure pumps are rated for pressures up to 240 bar (3,400 psi) for universal applications. They are also suitable for water re-injection. The system is insensitive to high solid content in the fluid and has a low energy consumption due to its high efficiency.

Type of Joints The Proper NEMO® Joint for Every Application The type of joint chosen is an important factor influencing the operating safety and the life cycle costs of a NEMO® Pump. Selection of the perfect joint will depend on the application, the operating conditions and the substances to be conveyed, as well as the pump model.

B Universal Pin Joint The NEMO® universal pin joint is the standard joint for NEMO® industrial pumps because of its simple design and outstanding reliability. To achieve a long service life, the joint is oil fi led and sealed by the NEMO® SM® seal. The joint can also be used without seal in case of extremely high temperatures and products where elastomers are not suitable. The joint consists of a minimum number of parts that enables simple dismantling for maintenance.	V Pin Joint The operational characteristics of the NEMO® V pin joint are similar to those of the B pin joint. For longer service life in difficult applications they are strengthened by hardened bushings fitted into boreholes in the coupling rod and the rotor/drive shaft head. The Vpin joints with hardened bushes are easy to remove for maintenance purposes. Standard on the 125 pump size.	H Hygienic Pin Joint The open, patented pin joint was designed specifically for use in hygienic pumps. It is crevice and dead space free, polished and, therefore, easy to clean. The joint is made in accordance with US 3-A Sanitary Standards.

F NEMO® Flextec Flexible Rod The flexible rod is wear- and maintenance free because there are no components moving against each other as in other joint types. Neither lubrication nor seals are required. Therefore, the flexible rod is suitable for high pressures and temperatures. The flexible rod is also free from crevices and dead spaces which allows it to be used for pumping highly sensitive products in aseptic conditions. It is designed in accordance with the US 3-A Sanitary Standards.	K Joint The patented K joint was designed for extremely arduous industrial applications involving constant pump running, frequent stop/starts or shock loads. It is kinematically designed so that the torque and axial loads are borne by separate elements within the joint. The joint is oil fi lled and hermetically sealed by two seals which are resistant (compatible) against the lubricant and the pumped product. Filling the space between the two seals with oil allows the use of the joints at pressures up to 12 bar (170 psi).	Z Double Seal Pivot Joint For the largest flows and pressures possible with NEMO® pumps where the torques and axial loads are at their highest (in bearing housing size NM 125SY and above) the pumps are fitted as standard with a cartridge type precision pivot joint. The joint is oil filled, hermetically sealed by two seals which are resistant (compatible) against the lubricant and the pumped product. It is suitable for continuous operation.
