An LVP that provides peristaltic pumping to removably couplable administration set tubing assemblies supplying medical infusate. The LVP includes a housing, a drive-train assembly, and a controller. The housing includes an assembly receptacle configured to receive an administration set tubing assembly. The drive-train assembly provides mechanical peristaltic movement within the assembly receptacle. The drive-train assembly includes a stepper motor located within the housing and a camshaft assembly, driven by the stepper motor and at least partially extending into the assembly receptacle. The camshaft assembly includes a unitary camshaft and a plurality of tube engaging members that cooperatively move according to rotation of the unitary camshaft. Further, the controller is located within the housing that controls operation of the stepper motor and the camshaft assembly.
