Abstract A well pump shield is disclosed. The shield comprises a hollow cylinder of outer diameter substantially equal to the inner diameter of a well casing and a smaller diameter hollow cylinder integrally formed at one end of the first cylinder and protruding therefrom; the two cylinders have a common longitudinal axis. The smaller diameter cylinder has an inner diameter slightly larger than the outer diameter of the pump pipe. The shield is slid onto the pipe and held in place by a hose clamp provided over the small diameter cylinder. The shield prevents foreign objects from reaching the pump and jamming it in the well case. The shield is also provided with an opening through which an electric cable to the pump may pass.
