ABSTRACT:
A portable pump removal equipment is provided which includes a collar to be secured to the upper end of a well casing, a pair of arms extending outwardly and upwardly from the collar with a wheel rotatably mounted on the outer ends of the pair of arms. A V-shaped guideway is mounted around the periphery of the wheel which releasably engages pipe pulled from the well casing. A latching mechanism on the wheel permits rotation of the wheel in a direction to withdraw the pipe and the pump from the well casing. Rollers mounted on horizontally extending axes on the upper surface of the collar permit the pipe to be withdrawn from the casing without engaging the casing wall.
