The invention relates to a method for supplying washing liquid to a digester ( 1 ) for cellulose pulp and a subsequent diffuser washing device ( 2 a, 2 b). A high, disturbance-free production capacity can be obtained by using a common feed pump (P 1 ) which, via a main feed line ( 10 ), supplies both the diffuser washing device and the digester with washing liquid in parallel. The first pump (P 1 ) establishes a pressure on the washing liquid which is in the interval 2-6 bar, and is preferably 4 bar, while the second pressure level, which is established by the diffuser pump device (P 2 a, P 2 b), is in the interval 6-12 bar, but is at least 2 bar higher than the first pressure level, and the third pressure level, which is established by the digester pump (P 3 ), is in the interval 12-25 bar The system becomes self-regulating in the event of any operational disturbances in the flow of washing liquid and, if the pumps are appropriate, a countercurrent flow of washing liquid through the system is essentially maintained. |
