Grundfos contributes to cleaning diesel gas


In a strategic co-operation with the engineering firm of Haldor Topsøe, Grundfos is developing equipment for the cleaning of heavily polluted exhaust from diesel-driven vehicles such as trucks, busses and vans. By entering this co-operation Grundfos is moving into a completely new market.

Whereas Haldor Topsøe possesses the technical competence within the waste gas cleaning area and catalytic converters, Grundfos is contributing with competence within development and production of pumping electronics and mechanics.

The Grundfos pump in question is a special version of the digital dosing pump introduced in the market last year. The dosing pump makes it possible to monitor and regulate extremely precisely the injection of urea in the catalytic converter. By doing so a heavy reduction of the injurious gasses and particles, straining the environment, takes place.

Grundfos Group President, Mr Niels Due Jensen, is pleased that the Grundfos Group - via the digital dosing pump- will contribute to a sustainable development in a completely new area:

"Normally our pumps are utilised in residential housing projects and the industry - this is the first time that a Grundfos pump is built into a car. This proves that our conscious efforts in respect of visions and innovation do result in ground-breaking products which can contribute considerably to a sustainable development in many fields - to the benefit of the environment and the daily lives of many people", the Group President said.

Both the EU and the USA are working on regulations for the limitation of pollution from trucks. The newly developed catalytic converter will meet these by removing a number of unwanted and injurious substances from the gas exhaust. At the same time it contributes in saving fuel, so that the pay-back time will be limited to two to four years.

The Danish catalyst converter will remove about half of the particles from the truck gas exhaust and almost all nitrogen oxides contributing to the smog in big cities. Finally, most hydrogen carbonates giving the diesel cars their bad smell will vanish.

Grundfos and Haldor Topsøe have both great expectations to the strategic co-operation and to the positive perspectives appearing when environmentally damaging gasses and particles from the diesel exhaust can be removed almost completely .

For the time being there will be a test period before the equipment is considered released for commercial production.

Multi screw pump moves highly viscous heavy oil at low NPSHa

22.02.2024 -

At a tank farm in a Brazilian sea port, two centrifugal pumps were used for transferring heavy oil from storage tanks to road tankers or vessels until February 2020. This required the high viscosity of the medium to be reduced by means of diesel injection, costing the owner at least 2,000 US dollars each day. In addition, the centrifugal pumps regularly broke down due to cavitation damage. The owners decided to initially replace one of the two centrifugal pumps with a NOTOS multi screw pump from NETZSCH. Due to its very good suction capabilities, the selected four-screw 4NS is also suitable for highly viscous media with up to 200,000 cSt, achieving a flow rate of up to 3000 m³/h.
