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
Brazilian hydroelectric power stations rely on pump know-how from Germany
While Germany still faces many unsolved problems in terms of implementing the energy turnaround, they have moved significantly further on in South America. Of all the countries, the developing nation of Brazil is proving itself to be the role model when it comes to renewable energies. Around 75 percent of the electricity requirement is covered by hydroelectric power there. 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
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
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
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.
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
Pump technology for maritime applications:
Universally deployable displacement pumps ensure reliable, smooth conveyance of a very wide range of media
When pumps are used on ships and in ports, the technology must meet special requirements: this means the pumps should not only cope with a really wide variety of fluids, such as wastewater and lubricant oil, but should also be as space-saving, maintenance-free and easy to handle as possible. Challenge... read more
A new generation of rotary lobe pumps performs bilge pumping and conveying tasks maintenance-free and in extremely limited space
wo things are severely limited on ships: space and time. Compactness is particularly vital in the machine room, as each centimetre means a loss at the expense of valuable transport capacity. At the same time, the systems have to be robust, as manpower can hardly be switched to repairs at sea and interim port stops are to be avoided at all costs for reasons of time. So maximum demands are placed on safety-critical systems such as bilge pumps. More
