Easy ways to get the answers you need.
1. Specifically designed to withstand the high torque levels encountered in screw pump applications.
2. Equipped with improved threading to maximize torque capacity.
3. The enhanced threading increases torque force by at least 50% compared to traditional API threaded connections.
4. Drive rods are available in rod body diameters of 1 inch (25.40 mm), 1-1/4 inches (31.75 mm), and 1-1/2 inches (38.10 mm).
5. Full-length heat treatment is applied to eliminate residual stress, with air quenching and tempering to refine and homogenize the grain structure.
