A bellows assembly for a fluid delivery system is a multi-component device that includes a cylindrical pressure jacket and a bellows syringe that is received within the pressure jacket. The bellows syringe includes a cap member and a bellows member. The bellows syringe in one embodiment is adapted to be secured to the pressure jacket by the cap member. The cap member is formed with a discharge port, which may be formed as conventional luer fitting. The discharge port is disposed coaxially within an annular wall on the outward facing side of the cap member and may be recessed within the annular wall. The bellows member is a hollow body that includes a series of bellows sections or rings. A distal end of the bellow member is formed with a discharge neck terminating in a discharge port, and the proximal end is formed with a closed end wall.
