ABSTRACT OF THE DISCLOSURE A long stroke, large force electromagnetic lin- ear motor and pump apparatus having concentric inner and outer magnetic circuits arranged coaxially and moving relative to one another in a rectilinear path with recip- rocating motion in response to the interaction of magne- tic fields produced by the inner and outer magnetic circuits, respectively. The invention further resides in a central core pump having a pumping tube connected for movement with the outer magnetic circuit and in coaxially alignment with inlet and discharge tubes and each of the three tubes having a check valve to form variable volume chambers between the pumping and inlet and pumping and outlet tubes respectively so that successive volumes of fluid are drawn into one and discharged from the other when the outer circuit moves in one direction and dis- charged from one and drawn into the other when the outer circuit moves in the opposite direction.
