Rod Pump Controller

Enhanced start/stop pump-off control using surface and downhole dynamometer plots for sucker-rod pumping systems.

Achieve the best start/stop pump-off control of your fixed speed, rod pumped wells with Unico Rod Pump Controllers. Unico RPCs have sophisticated modelling and advanced control to compute surface and downhole conditions to best regulate the pumping unit operation.

Comprehensive monitoring and reporting provide real-time surface and downhole dynamometer plots, daily gauging, fault and event logs, user configurable data logger and more.

The RPC unit can control any conventional pumping unit and most hydraulic lift units, also providing optional engine control.

Multiple communication options are available and when coupled with GMC web-based telemetry software, users can monitor operations from around the world.
