ePAC™ Electric Submersible Pump (ESP) System

Designed for oilfield pumping applications, the ePAC, goes beyond conventional variable frequency or speed drives, incorporating flux vector technology for precision control of both speed and torque. This system allows optimization of electric-driven artificial lift systems. The drive provides a number of features specifically designed for ESPs.

• Overload and underload detection protect submersible motors and pumps from damage
• Current limit control increases production from gassy wells by increasing motor speed during periods of reduced pump load
• Auto-restart returns the drive to operation, after an adjustable period of time, once the fault has been cleared
• Extensive electronic protection circuits reduce failures
• Rapid restart minimizes lost well production due to momentary power outages
• Real-time data logging of production information
• Flux vector operation for precise control of motor current and torque
