ABSTRACT:
A magnetic pumping system includes a pump, capable of urging a fluid therefrom during a forward stroke and a return stroke, having a piston disposed within a cylinder defined by a pump body, and a driver disposed external to the pump body. The driver is capable of moving the piston by a magnetic field interaction between the driver and the piston. The system further includes a check valve bridge, spaced away from the pump and in fluid communication with the cylinder, capable of allowing ingress and egress of the fluid into and out of the cylinder in response to a movement by the piston.
