Rock-It Mud Motor Rental

Get more power. Use less fluid. Rock-It Mud Motors convert drill fluid pressure into maximum torque so you get more drilling time before stopping for maintenance. It’s not magic. It’s just Melfred Borzall engineering.

  • High-performance mud motor designed specifically for HDD
  • Can be operated at a slower speed for more compatibility with tri-cone bits
  • High torque-to-flow ratio means more drilling power with less fluid
  • High-quality internal parts result in more drilling time before regular maintenance is required
  • Mud-Motor rentals available
  • Bearing packs are designed to be completely sealed
  • Rotors and stators are designed for HDD. They are shorter in length to help with the steering of the motor. All stators are manufactured with a new “hard” nitrile rubber resulting in more power from the motor.
  • Built tough to withstand the harsh conditions of horizontal drilling. Stator tube walls are twice as thick as other brands for maximum durability.
