Success stories in the environmental & energy sector

NEMO® Progressing Cavity Pump Conveys Healing Water

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. More...

NEMO® Progressing Cavity Pump with FSIP® Ensures Uninterrupted Loading

Turning two into one: A water company needs one less unit thanks to FSIP® pump design

A water company in Northern Italy used two progressing cavity pumps of the NEMO® BY type in block construction design. One of them has being used to convey sludge into the centrifuge, while the second was permanently in standby mode. More...

NEMO® Progressing Cavity Pump with xLC® Stator and FSIP® Delivers Reliably

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 Progressing Cavity Pump with aBP-Module® Prevents System Downtime

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...

TORNADO® T.Envi® Rotary Lobe Pump Facilitates Industrial Wastewater

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, the T.Envi® is designed for a long service life with minimum wear. More...

Rotary Lobe Pumps Convey even Highly Abrasive Residual Water

Reliable sludge removal for water jet cutting: Robust rotary lobe pump even pumps highly abrasive residual water

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 area. A cutting aid, an abrasive, is mixed into the water to increase cutting performance. More...

NEMO® B.Max Progressing Cavity Pump Convinces through its Robustness

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...

Low Material Wear in spite of High Loads with the NEMO® BT Immersible Pump

NEMO® BT immersible pump conveying beet pulp straight from the lagoon with low material wear

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...

Hydroelectric Power Stations Rely on NOTOS® Multi Screw Pumps

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. More...

Save Electricity and Substrate Feeding with the NEMO® B.Max® Mixing Pump

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). More...

NEMO® Progressing Cavity Pumps Process Everything

Robust pumps enable a range of substrates to be conveyed, from liquid manure to food waste

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...
