The Effective Digital Solution For Production Control
The Guardian™ Variable Speed Drive (VSD) provides an effective digital solution for production control by providing the operator complete control and monitoring of progressing cavity pump systems. A combination of precise torque and speed control in a single durable package is the key to providing maximized production, energy efficiency and total protection of PC pumping systems.

Take Control
The proprietary Guardian software incorporates a complete model of the total PC pumping system. Precision torque and speed control, combined with the proven software program, provide continuous feedback of torque, speed, pump efficiency, fluid rate and estimated down-hole pressure. This feedback, measured against operator set points, allows the Guardian to provide a highly effective control method for protecting down-hole equipment and maximizing production.

Fluid level over the pump intake is controlled with manual speed adjustments, or automatically with the system software. Operator set points allow the Guardian to adjust pump speed to meet ever changing down-hole conditions. A power optimizer reduces electric utility cost for any inflow rate.

Other Guardian VSD Features Include:

• Monitors the PC pump, motor, rod speed and torque
• Pump flow monitor and production accumulator
• Embedded data in software for rod string, tubing, reservoir and PC pump model
• Fluid level monitor and control
• Interface software for remote monitoring by network servers
