Beam Balanced pumping units have been designed to API (American Petroleum Institution) standard requirements for pumping unit design. In addition, all individual components of the unit and the unit as a whole represent the very best engineering design, production facilities, quality and field experience.
The Beam Balanced pumping unit is a Class I lever system having beam counterbalance. The Beam Balanced unit may be operated in either direction of rotation. The four bar lever system converts rotational motion at the crank to reciprocating motion at the horsehead and in turn to the downhole pump.
Beam Balanced pumping units have been designed to API standard requirements for pumping unit design. In addition, all individual components of the unit and the unit as a whole represent the very best engineering design, production facilities, quality and field experience. The Beam Balanced unit will give many years of dependable service when properly installed, maintained and operated within its load and torque ratings.
