reduction is accomplished by using a gear reducer, and rotary motion of the crank shaft is converted to oscillatory motion by means of a walking beam. The crank arm is connected to the walking beam by means of a pitman arm. The walking beam is supported by a Samson post and saddle bearing. The horse head and bridle are used to ensure that the pull on the sucker rod string is vertical at all times so that no bearing movement is applied to that part of the sucker rod string above the stuffing box. The polished rod and stuffing box combination is used to maintain a good liquid seal at the surface.

is the visible above-ground drive for the well pump, and is connected to the downhole pump at the bottom of the well by a series of interconnected sucker rods. Sucker rods are also commonly available made of fiberglass in 37 1/2 foot lengths and diameters of 3/4, 7/8, 1, and 1 1/4 inch. These are

The surface unit transfers energy for pumping the well from the prime-mover to the sucker rod string. In doing this, it must change the rotary motion of the prime-mover to reciprocating motion for the sucker rod. And it must reduce the speed of the prime-mover to a suitable pumping speed. Speed
