Valmet Pressure diffuser

Valmet’s pressure diffusers are primarily used for washing in a digester blow line and as a first washing stage in an oxygen delignification system.

Valmet pressure diffusers enhance pulp washing in a number of ways. Among them are very efficient pulp washing, closed design and reliable operation.

Several unique features enable the high washing efficiency of Valmet pressure diffusers. Long diffusion time at a high temperature is the key factor to the high efficiency. The closed design assures complete environmental safety in terms of malodorous gas emissions or liquor spills. Another great benefit is that a pressure diffuser requires very little space, meaning they can be easily fit into a fiber line retrofit or into new lines. Easy connections for piping and support systems simplify installation.
