    • A machine and process for washing paper stock pulp and other vacuum-filterable materials includes a wash drum (10) mounted in a tank (30). Two endless filter belts (50 and 52) are trained to pass around the wash drum (10) and through wash liquid contained in the tank. A mat of pulp is formed between the two endless filter belts (50 and 52) and carried on the wash drum (10) and through the tank (30) for washing therein. Wash liquor is pulled by vacuum through the pulp mat as it travels under the drum (10) thereby washing the pulp mat. After the pulp has been washed it is removed from between the two belts (50 and 52).
