Environmental & Energy - Pumping Solutions
Almost every industry that interacts with the natural ecosystem would require environmental applications to clean the damage that’s made. NETZSCH has a unique line-up of environmental pump solutions that you can easily integrate into your existing process.
Our TORNADO Rotary Lobe Pumps and NEMO Progressing Cavity Pumps when used in combination with our macerators are not just energy efficient but can also keep your operation environment-friendly. They are highly-reliable and custom-engineered to transfer even the most complex media like wastewater, sludge, and even slurries in the biogas / renewable energy industry.
What are some of the proven environmental & energy applications which use NETZSCH pumps?
Water, Lubricant & Fuel Sector
- Hydro Power Plants
The operation of a hydropower plant heavily relies on fluids such as water, lubricants, fuel, and Environmental Equipment. NOTOS, our multi-screw pumps comes in handy here as it can transport high-density lubricants and fuels, with ease.
- Sludge Conveyance
NETZSCH’s NEMO is an energy efficient Pump that can help you convey sludge into a centrifuge or anywhere you need. Our TORNADO pumps can also help you handle highly abrasive sludge from the waterjet cutting process.
Biogas & Renewable Energy Sector
- Biomass Transport & Mixing
Biogas production involves transporting and mixing highly viscous biomass substances. Owing to their high mixing capacity, one would need a robust machine like our NEMO B.Max pump, to get the job done.
- Small Biogas Plants
Small bio-plants are often forced to use their operational waste sensibly owing to the reductions in subsidies that are provided to them. Our NEMO environmental pumps can ensure increased efficiency, low cost of operation, and effort. The conveyance volumes can be modified based on your requirements.
- Bio-Waste
NETZSCH’s NEMO and TRONADO pumps are an excellent choice of Environmental Pumping Solutions which can help convey a diverse range of substrates, that are produced during biogas extraction with high operational efficiency and low maintenance.
Extraction of saturated brine
Especially designed progressing cavity pump conveys spa water from a Glauber’s salt spring in Saxony
In September 2015, new 4,500 m² salt water thermal baths were opened in a spa town in Saxony that is steeped in tradition. They are fed from a highly-saturated Glauber’s salt spring which an environmental company investigated by drilling in 2009. Ready more...
Turning two into one: regional water company needs one less unit thanks to special, maintenance-friendly FSIP® pump design
A regional water company in Northern Italy used two progressing cavity pumps of the NEMO® BY type in block construction design for sludge dewatering. One of the pumps has being used to convey sludge into the centrifuge, ...more
Tripling service life in a waste water treatment plant
xLC® stator adjustment system permits situation-specific adaptation on NEMO® progressing cavity pump.
The thickened sludge of a waste water treatment plant should be boosted into an intermediate tank. “The solids content is more than eight percent, so that the wear caused by the medium is expected to be very high”, says the head of the purification waste water treatment plant. More
NEMO® BP hopper-shaped progressing cavity pump with aBP-bridge breaker prevent the constructions stop
There are two aspects of wastewater treatment plants at Celle (Germany) which have a direct use: in addition to cleaning waste water, the sewage sludge which arises with the nutrients it contains can be used later as manure in agriculture. More...
Low-wear conveyance of industrial waste water:
Robust TORNADO® rotary lobe pumps make water treatment easier
Used service water from industrial processes is one of the most problematic types of waste water due to its composition, which is often very demanding for conveying systems. In order to enable problem-free treatment of this kind of waste water in spite of this, More...
Reliable sludge removal for water jet cutting:
Robust rotary lobe pump will even pump highly abrasive residual water without any damage
Cutting systems, which are based on high-pressure water jets and do not alter the material structure through their energy input like lasers do, are establishing themselves in more and more areas, such as robotics or automotive manufacturing. A cutting aid, an abrasive, is mixed into the water to increase cutting performance. This abrasive is frequently a fine garnet sand. After the cutting process, the water-sand mixture has to be separated again, so that the sand can be disposed of. A manufacturer of water jet cutting systems offers an automated solution for its systems to remove and separate the sludge from the water. More...
Biogas systems as top exports:
German pump technology proves successful thanks to high mixing performance and
robustness in bioreactors worldwide
The boom of environmentally friendly power and heat generation from renewable biomass continues. Especially countries such as the UK, France, Japan or the US discovered the advantages of renewable energies, primarily the use of biogas. ... more
Conveying beet pulp straight from the lagoon
Beets, particularly sugar beets and specially-bred energy beets, are becoming more and more popular. The storage of the beets in silos or silage tubes is complicated and expensive. Collecting beet pulp in foil-lined reservoirs represents a comparatively simple and cost-effective alternative to this. More
Hydraulics and lubrication for turbines weighing many tonnes:
Brazilian hydroelectric power stations rely on pump know-how from Germany
Responsible for the environment and climate change, renewable energies are becoming increasingly important. Therefore, where the prerequisites are met, more and more hydroelectric power plants are being connected to the grid. Some of the world's largest hydroelectric power plants are operated on large rivers in Brazil. More
Operating small biogas plants efficiently:
special feed and homogenisation technology saves power and substrate
The reason for the slowdown of the large biogas boom in Germany were the reductions in subsidies and above all changes in aid made by the amendment to the German Renewable Energies Act (EEG). For farmers, who are particularly targeted by the current reduction of subsidies for small plants, this is a strong reason to use their operational waste sensibly and to produce environmentally friendly energy from it in the most efficient way possible.

Robust pumps enable a range of substrates to be conveyed, from liquid manure to food waste.
[Translate to English (India):] Biogas is in high demand as a source of energy for power and heat generation. Systems that not only process crops specifically grown for power and heat generation, but also use otherwise useless bio waste, are excellent for the environment and are highly economical. More
