* Our hydraulic rotary heads are supplied with different gear ratios and in different motor configurations to adopt torque and drilling speed to your specific needs.
We also supply air/water swivels and mounting plates according to existing leader dimensions.
Technical features:
- Protecting wear rings prevent shrinking of the seals on the shaft
- Central lubricating pump ensures constant lubrication of the complete rotary head in every drilling position
- Bearing system of the main shaft was taken from our hydraulic drifters which ensures long durability
- Modular design guarantees easy maintenance and reduced spare parts cost
