Magnetic pumping systems and methods of pumping using such systems are disclosed. In one embodiment, a system for pumping fluid comprises: a substantially cylinder-shaped pump housing (200); a magnetic piston (210) residing within the pump housing (200) for displacing the fluid; a magnetic actuator (220) surrounding the pump housing (200), wherein the magnetic actuator (220) is configured to move the piston (210) by a magnetic force between the magnetic piston (210) and the magnetic actuator (220); and a magnetic ring (230) surrounding and attached to the magnetic actuator (220) for increasing a magnitude of the magnetic force. In another embodiment, a system for pumping fluid comprises: a pump housing (10); a magnetic piston (20) residing within the pump housing (10) for displacing the fluid; an electromagnetic actuator (150) outside the pump housing (10) comprising a movable conductive coil (160), wherein the electromagnetic actuator (150) is configured to move the piston (20) by an electromagnetic force; and an external driver for moving the conductive coil (160).
