Drive Rods (TM)
Item Code: 9302
A key component to any PC Pump system is the rod string. It must transmit the necessary torque from the surface drivehead down to the pump rotor, while resisting the axial loading created from the hydraulic forces in the pump and weight of the rods themselves.
Drive Rods™ have been specifically designed to be able to transmit high torque requirements while at the same time, minimizing flow losses created by the rod couplings. Patented connections with cold-formed rolled threads and only the highest quality raw material make the Alberta Oil Tool Drive Rods™ the premier choice for PC Pump applications. That is why we are proud to be an exclusive distributor for the AOT Drive Rods™.
