18 July 2024: Contaminant-loaden stock flows in pulping systems for recovered paper can only be conveyed reliably and largely blockage-free with a special pump. Whether in the LC or HC system, the new IntensaPump reliably pumps critical contaminants to the next machine in both systems.

“Compared to its predecessor, the Contaminex CM, the IntensaPump combines a wide range of benefits for our customers, such as higher throughput with reduced energy requirements, lower maintenance requirements and improved runability. These advantages make the IntensaPump a new addition to our comprehensive BlueLine portfolio and the Intensa family,” says Wolfgang Müller, Global Product Manager Pulping.

Voith’s BlueLine portfolio includes modern machines and products for stock preparation that are characterized by efficient energy and other raw material consumption as well as gentle fiber treatment.

Technical advancements enable customer benefits
Large debris can easily pass through the pump housing, as the large nozzle and housing space, as well as the recessed vortex impeller, prevent the IntensaPump from clogging. A frequency converter enables optimized pump speed with reduced energy consumption for discontinuous pump operation. During pumping pauses, when no medium is being pumped, sediment and wear-promoting parts are deposited in the horizontal nozzle and prevent further circulation in the pump housing.

“By installing the IntensaPump on our OCC 3, we had far fewer blockages in the pump and were able to save a lot of time and maintenance work. At the same time, we need less energy during operation, which has a positive impact on our CO2 emissions and costs,” says Osman Özkeser, Project Manager of the OCC 3 rebuild at Modern Karton.

In combination with the IntensaPulper, IntensaMaXX and IntensaScreenDrum, the IntensaPump is part of Voith’s BluePulpLC system, which is likewise designed for the lowest fiber consumption, lowest maintenance costs, reduced energy consumption and best runability.
