Various aspects of the subject disclosure relate to a compounder system having a cartridge that includes controllable fluid pathways. One or more rotary piston pump/valves may be used to move fluid and/or gasses through the various fluid pathways of the cartridge. For example, the cartridge may include a dedicated rotary piston pump/valve for each process that moves fluid and/or gas through the cartridge. When turning, the rotary piston pump/valve acts as a pump to move the fluid or gas, and when the rotary piston pump/valve stops turning, it effectively acts as a shutoff valve, preventing any fluid flow. Magnetic couplers for the cartridge may be provided on a pump head of the compounder system. 1. A compounder system , comprising: a plurality of controllable fluid pathways fluidly coupled to at least one diluent port, a waste port, and a receiving container port; and', 'a rotary piston pump/valve rotatable to control movement of a fluid through at least one of the controllable fluid pathways., 'a cartridge having2. The compounder system of claim 1 , further comprising at least one additional rotary piston pump/valve rotatable to control movement of another fluid through at least another one of the controllable fluid pathways.3. The compounder system of claim 1 , wherein the rotary piston pump/valve comprises a gear coupled to a rotary piston having a cavity.4. The compounder system of claim 3 , wherein the rotary piston pump/valve further comprises a cam surface for linearly actuating the rotary piston during rotation of the rotary piston by the gear.5. The compounder system of claim 4 , wherein the rotary piston pump/valve further comprises a housing in which the rotary piston is disposed claim 4 , the housing having an input port and an output port.6. The compounder system of claim 5 , wherein the rotary piston is configured to linearly actuate in a first direction claim 5 , due to cam action on the cam surface claim 5 , as the rotary piston is rotated away from ...
