Pumping cartridges are disclosed for use in pumping systems. One such cartridge includes a series of fluid flow paths therein and a bypass valve therein, the bypass valve can selectively block fluid flow along one or both of two fluid flow paths through the valve. In some embodiments, the pumping cartridges are removable from a reusable pump drive component. In some embodiments the pumping cartridges comprise a substantially rigid component having one or more channels and/or depressions therein covered by a membrane so that together the rigid component and the membrane define a series of fluid flow paths, pump chambers and fluidic valves, including a bypass valve.
