Abstract: A sand check filter for preventing solids from reentering into a pump. The filter is designed to mount atop a conventional rod pump. The filter allows well fluid, that contains high solids, to pass through the pump under normal operation while eliminating the solids from being swept back into the pump barrel. The filter includes a sleeve that has radial flutes that allows the sleeve from hanging up, sticking to or wedging itself to the valve rod. The sleeve is rotated on the valve rod to create a valve effect atop the filter. This prevents the fluid from passing through the inner diameter of the screen and forces solids within the fluid to be redirected to the outer diameter of the filter. This allows the fluid to be filtered before reentering the pump.
