A magnetically-actuated, motorized pump includes a plurality of cylinders extending at radially-spaced intervals between first and second heads. Each cylinder reciprocably receives a piston assembly including a pair of permanent magnets with outwardly-extending poles. Inlet and outlet valves are each provided at opposite ends of the cylinders. First and second rotors are each rotatably mounted at a respective end of the pump outside of a respective head. Each rotor includes a concentric ring comprising alternating permanent magnets and electromagnets for reciprocating the piston assemblies. Perimeter magnets are provided on the first rotor and the first head for interacting whereby rotary motion is imparted to the rotors. The electromagnets are actuated by an electrical distribution system.
