Heidenheim, Baden-Wuerttemberg, Germany, 2011/03/23 - With the new DeaerationFoamPump (DFP) 4000, Voith Paper sets a new benchmark for foam deaeration - VoithPaper.com. FSE: VO2A
The pump reduces the air content in the foam mass to as low as 8%. At the same time, it takes up less space and can be placed on the same level as the flotation machine.
The DFP 4000 is both a pump and deaeration machine in one unit. As one compact unit, it replaces the foam destroyer, foam tank, stirring unit and pump. For the papermaker, this means a clear reduction in their investment costs, while expenses for an additional tank, stirring unit, pipes, and pumps are eliminated. Another plus is that the DFP 4000 creates additional floor space, since it does not necessarily have to be positioned underneath the flotation machine. Instead it can be placed right at the foam outlet of the system.
The DFP 4000's deaeration works in two process steps. In the upper part, the fed-in foam is pre-deaerated mechanically; in the lower part, the centrifugal forces bring about a subsequent deaeration. Use of a separate foam tank is no longer required with the DFP 4000. After deaeration, the suspension is conveyed to the next process stage with an air content of as low as 8%. The DFP 4000 thus achieves a better deaeration result than conventional systems, which have 12% air content on average at the outlet.
The DFP 4000 (patent pending) has already convinced many customers in Europe, Asia and America. Due to the excellent results achieved by this new development, the DFP 4000 will in future be implemented as standard in all Voith flotation systems.
