American Maximizer II – Phase Crank Special Geometry

7/16/2019 Max I & Max II


Maximizer II advantages

Higher efficiency

Exclusive crank rotation allows more rotation on theupstroke. This combined with the most effective counter

balance phasing, creates lower net torque in more

applications than any other pumping unit.

The enhanced geometry delivers more lifting with less

horse power which results in maximizing production and

energy efficiency.
