The BERNOULLI-PRINCIPLE in Filtration Putting a 250 year-old physical principle into practice A disc moved by a piston generates high local increase in flow velocity between the flushing disc as it moves into the screen and the filter insert. The resulting drop in pressure gives contract-free cleaning of the screen and the particles escape via the flushing valve, which, when opened, creates a pressure difference with the working pressure, thus discharging the particles. With its outstanding flow mechanics based design, the filter only generates a very low pressure drop in the system. The result...

KAF Bernoulli Filtration and Flushing Phases DN 40 - DN 1000 Filtration The filter is in the normal filtration phase. Given the laws of flow mechanics, the particles are progressively deposited in the screen in a top to bottom direction. As a result of the design and resulting flow mechanics environment, in this phase no particles are deposited in the filter inlet area. • Very low differential pressure during filtration • Screen with high capability for particles retention Filtration and continuous flushing initiation During the flushing phase, the flushing valve opens, generating a difference in...
