Success Stories in the Environmental & Energy Sector

Sea and Salt Water Transfer Pumps

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...

Sludge Transfer Pumps

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

NETZSCH Thickened Sludge Transfer Pumps

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


NETZSCH Pumps in Wastewater and Sludge Treatment

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. The sewage sludge is transported via a pressure pipe around 25 metres in length with several right-angled turns – ten metres of it being geodesic – to a silo and from there it is later spread over agricultural areas. So that the mix can be stored, it is first dewatered in an angle press and flocculating agents are added. More

NETZSCH Pump in Wastewater Sewage and Sludge Treatment

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...

NETZSCH Water Jet Cutting Pumps

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...

NETZSCH Biogas Pumps

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

NETZSCH Pumps for Biogas / Agriculture

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

NETZSCH Pumps for Hydroelectric Power Plants

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

NETZSCH Pumps for Small Biogas Plants

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.

Bio Waste Processing Pumps

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

NETZSCH Product Range of the Environment & Energy Industry

NEMO® Progressing Cavity Pumps

NEMO® Progressing Cavity Pumps have a very broad application range and are used in all branches of industry for the continuous, pressure-stable, gentle and low-pulsation conveyance of almost any substance. One advantage for the operator is that such a valveless positive-displacement pump is also capable of transporting stringy material safely.
