DOWNHOLE MOTOR/ MUD MOTOR

1. About the Manual
The SEACO Drilling MOTOR is a powerful and reliable positive displacement motor. The motor generates an optimum balance of rotational speed and high torque to drive a variety of drill bits at speeds that maximize tool life and performance. SEACO MOTORS offers a choice of flow rates, speeds, and torques to match a wide range of operational parameters. SEACO MOTORS are used in applications such as straight hole drilling, directional (steerable) drilling, horizontal drilling, hole opening, and re-entry(work over).
