Sensia Unico’s Sucker-Rod Pump Drive (SRP™)

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.

Our sucker rod pumping system drive will help you increase your production process by making it more efficient and less time-consuming. It comes in power levels ranging from 10 to 200 hp with stroke lengths of 24 to 360 inches.

The drives can operate all basic types of artificial lift systems, including the beam balanced, crank balanced, air balanced, phased crank, reverse mark, bent beam, and Rotaflex pumping units. Unico’s SRP drive has many features, including packaging for hostile outdoor (topic to arctic) environments, automated identification of system parameters, well report generator, down-hole pump leakage estimator, pump travelling and standing valve check, patented sensorless measurement of surface and down-hole dynamometer cards, and many others.
