An improved beam pumping unit for pumping fluids from a well having a foldable support structure to allow storage of the pumping unit in a low profile position. The beam pumping unit utilizes a walking beam pivoted on a central bearing, a drive means connected to one end of the walking beam to oscillate the walking beam and a horsehead at the other end of the walking beam for connection to the polished rod of the downhole pump. A foldable Samson post supports the central bearing of the walking beam. The foldable Samson post allows lowering of the pumping unit from a first, fixed standing position in which the walking beam is raised for normal pumping operation and a second, fixed lowered position for storage.
