Unico's Sucker-Rod Pump Drive (SRP™) provides superior control of conventional, air-balanced, beam-balanced, phased-crank, Mark II, Reverse Mark, and Rotaflex artificial lifts. The drive integrates motor control, speed optimization, logic, pump fill control, and rod load control into a single, compact solution that increases production, improves energy efficiency, and enhances the reliability of both new and existing pumping systems.
