Cups seal the cleaning tool within the pipeline while guiding/centralizing it for optimal run behavior. The tool’s forward motion is generated by the flow of the medium and the differential pressure between the front and back of the tool. Cups generally provide inferior cleaning (compared to discs), and they have only unidirectional run capabilities. Cups may be used in the first phase of cleaning campaigns where a large amount of debris is expected. These cups are made of ROSEN's unique polyurethane brand RoPlasthan® 1200 and have a hardness of 75 Shore A. ROSEN's RoPlasthan® urethane material, especially developed for pipeline cleaning and inspection purpose, offers highest wear resistance and therefore offers superior cleaning and sealing ability.
