Abstract: A modular fluid delivery system is disclosed which comprises at least one supply station for supplying at least one fluid, and a pressurizing unit for pressurizing the at least one fluid, the pressurizing unit comprising at least one driving unit and at least one disposable pump module assembly. The disposable pump module assembly comprises at least one disposable pump module and a fluid circuit tubing. The disposable pump module comprises a supporting element which defines at least one chamber, at least one inlet fluid circuit pathway, at least one outlet fluid circuit pathway and at least one recirculation fluid circuit pathway. The fluid circuit tubing comprises at least one inlet fluid circuit tubing, at least one outlet fluid circuit tubing and at least one recirculation fluid circuit tubing.

Abstract: A fluid delivery system is disclosed which comprises at least one first supply station for supplying a first fluid and at least one second supply station for supplying a second fluid different from the first fluid. The fluid delivery system further comprises a pressurizing unit for pressurizing the first and second fluids, said pressurizing unit comprising first and second pump modules, and each pump module comprising a chamber and a piston provided with a plunger to define first and second variable-volume sub-chambers. The fluid delivery system further comprises first and second inlet fluid circuits, first and second outlet fluid circuits, and a first recirculation fluid pathway fluidically connecting the first and second variable-volume sub-chambers of a pump module. Moreover, a first actuator is associated to said first recirculation fluid pathway for managing the fluid passage in both directions between said first and second variable-volume sub-chambers of said pump module.
