The Weatherford Rotaflex long-stroke pumping unit combined with ForeSite Power regenerative system VSD and the PMM direct drive creates next-generation energy efficiencies from all three technologies, providing higher levels of production performance and cost-saving value.

Top graph shows ForeSite Power regenerative VSD produces more kWh output than its kWh input, resulting from the reuse of otherwise wasted energy. The bottom chart graphs the efficiency trend resulting from the reuse of the otherwise wasted energy.
