Instructions
The YONDA YDR12000V hydraulic rotary head features a variable-displacement piston motor with stepless speed control, allowing rotary output to be adjusted to different drilling requirements. Depending on the displacement setting, it delivers torque up to 16,500 Nm or rotation speeds up to 230 rpm for drilling rig integration and upgrade projects.
An integrated air/water inlet and compact structure support installation and piping layout. For offshore drilling projects, ball valve and API connection configurations can be evaluated to match the required drill string interface and operating arrangement.
Key Features
- Variable displacement and stepless speed control: Adjust rotation speed and torque to suit different drilling requirements.
- Torque up to 16,500 Nm: A low-speed, high-torque operating option.
- Rotation speed up to 230 rpm: A higher-speed operating option at the corresponding displacement setting.
- Integrated air/water inlet: Air and water inlet provision incorporated into the rotary head.
- Project-specific configuration: Ball valve and API connection arrangements can be evaluated for the rig and drill string requirements.

FAQ
1. Does the YDR12000V have only three fixed speeds?
No. The YDR12000V uses a variable-displacement piston motor for stepless speed control. The three speed and torque combinations in the catalog are reference operating points at different displacement settings, rather than three fixed speed options.
2. Can the YDR12000V deliver 230 rpm and 16,500 Nm simultaneously?
No. These values correspond to different displacement settings. The catalog lists 5,000 Nm at 230 rpm and 16,500 Nm at 70 rpm. Selection should be based on the speed and torque combination required for the application.
3. Can the YDR12000V be configured for offshore drilling?
Yes. Project-specific configurations can be evaluated for offshore drilling. The featured unit includes a ball valve and API connection for planned offshore use. Suitability must be confirmed against the drilling method, drill string specifications, hydraulic system and mounting requirements.
4. Can the YDR12000V replace an existing rotary head?
Replacement can be evaluated after reviewing the existing rig and rotary head specifications. Please provide model details, mounting dimensions, hydraulic pressure and flow, required speed and torque, and drill string connection specifications.
