MG-750-GRA Electric Gear-Reduction Drive Provides a reliable, economical solution for a variety of PCP applications, including heavy to light oil, coalbed methane, and water source wells

Applications
• PCP applications driven by electric motors, hydraulic motors or internal combustion engines
Features and Benefits
• The centrifugal braking system provides a resistive torque that is proportional to speed, for a safe release of the backspin energy. The brake shoes automatically engage and retract based on speed,
which results in a quick, complete, and controlled fluid dump, enabling production to resume quickly.
• A specially designed motor shaft cover enables exchanging the electric motor without removing the driver sheave, which saves time and increases operational efficiency.

Tool Description
The Weatherford MG-750-GRA drive is a belt-driven, gear-reduction drive with a torque capacity of 750 lbf-ft. It is compatible with Weatherford stuffing boxes and various wellhead connections. The
drive features an internal 3:1 gear reduction and up to a total combined speed reduction ratio of 15:1.
