摘要： A pump comprises a frame and a docking platform connected to the frame. A motor is mounted to the docking platform and has a rotatable drive shaft extending therefrom. Roller bearings are mounted to cross beams attached to the frame. A vertically reciprocable slide bar driven is reciprocable through the at least one pair of roller bearings. A pump rod connector is attached to the slide bar and connectable to a pump rod extending into a well.
