A multiple function pump station (PPN) performs different on-line processing tasks. The pump station can be operated in one mode to draw blood from a donor and can in another mode be operated to return blood to the donor. The pump station used to draw blood from a donor can also be used to perform subsequent blood processing tasks, such as mixing processing or additive fluids with the blood, or transferring a harvested blood component to a storage container, or finishing the processing of a harvested blood component, e.g., by passage through a filter (200) to remove leukocytes.
