Maximizer II® Pumping Unit
Recovering more uid with less energy The Maximizer II pumping unit offers benets typically not found in conventional pumping units. Through its unique design features, the rear-mounted pumping geometry of the Maximizer II unit exhibits higher mechanical efciency and allows more crank rotation during the upstroke pump llage. The pump design of the Maximizer II unit allows the counterbalance moment to be phased in a way that optimizes the lifting cycle, further decreasing gear-reducer torque and energy requirements. Enhanced geometry delivers greater productivity at a highly efcient rate.
Tangible benets over conventional geometry • Gearbox reducer torque is lower in some cases, allowing for a smaller unit. • Lower horsepower requirements enable the use of a smaller prime mover to reduce lifting costs. • Slower upstroke allows more time for pump llage.
Tangible benets over push-up special geometry • Extended distance from the wellhead for easier and safer well servicing. • Reduces structural imbalance. • Smaller torque factors provide higher mechanical efciency. • Improved permissible load characteristics, including reduced loading on low-speed shaft and bearings. • Reduces polished-rod acceleration during the critical rst 40 percent of the downstroke. • Reduces uid pound effects, resulting in longer rod lift and less downtime. • Increases useful permissible-load range when both types are loaded with counterbalance to achieve maximum structure loading. • Increased uniform loading of prime mover results in lower energy costs. • Requires six to eight percent less energy to lift the same amount of uid as push-ups.

Pumping Units–Enhanced Geometry
Another means of eva luating the efcien cy of a pumping uni t is the shape and r ange of the permissible-load diagram. The horizontal shape and wide permissible-load range for any given counterbalance value makes the Maximizer II® unit ideal for a broad range of operating conditions. The geometry of the Maximizer II unit also contributes to reduced torsional loads on the gearbox, which can result in signicant reductions enabling the producer to use a smaller gearbox in some cases. These reductions may increase some internal structural loads, which are fully compensated for in the Maximizer II unit by using heavier structural materials and larger structural bearings. By design, the Maximizer II pumping unit provides more open area around the wellhead for personnel and equipment when workover is required. This advantage results in easier, safer working conditions. The Maximizer II pumping unit is available with gear-reducer sizes 320 to 1824.

StrapJack® Pumping Unit
Rod pumping under irrigation systems and visually sensitive areas The StrapJack pumping unit combines maximum stroke length and minimum height requirements for continuous operation under active irrigation systems. With its low-prole design, this unit is uniquely suited for special applications where visibility should be minimized, such as in parks and r esidential areas.
Engineered for safety and economy The StrapJack unit is designed so that the carrier bar remains above the base of the skid at the bottom of the downstroke. This conguration means that wellhead cellars can be much shallower and in some cases eliminated. Where a cellar is required, it is often less than 4 ft (1.2 m) deep, eliminating the “conned entry” designation and saving considerable maintenance expense.
Irrigation System Clears StrapJack Unit
Features, advantages and benets • Low-prole design makes the StrapJack unit suitable for low-clearance applications, such as rod pumping under sprinkler systems. • Low visibility contributes to positive relationships with landowners. • The design of the StrapJack unit in many cases eliminates the need and associated costs of a cellar, alleviating the risks associated with gas collection and conned entry. • Upstroke/downstroke velocities are essentially equal, resulting in the same geometry in both directions for smooth, consistent operation. • The StrapJack pumping unit is designed to operate without a horsehead, reducing visual impact. • The unit ships fully assembled for reduced setting time and costs and easy transport. • Samson-post third leg folds for easy well servicing.
