Premodrill 50: The new technology for efficient drilling

The own developed STDS-Jantz drilling rig Premodrill 50 sets new dimensions to the well drilling industry.

Premodrill 50 convinces with its simple operation via a remote control panel for driving , all drilling functions and also winch, mud pump and hydraulic casing extraction clamp.

Strong advantages for practical use:

Compact and robust design
Remote control for safe and ease of working
Emission and energy efficient
Use of Regulated power motors and pumps
Only components from renowned manufacturers

More power and energy efficiency with electronically controllable valve technology. The drive concept consists of a load-sensing pump unit (variable as a closed center) and a constant circulation pump (open center). By using modern electronically controlled valve technology, consumers can adjust for variety drilling processes – for example, by variable controllable preference functions, load independence and power shifts.

The machine has a 4-cylinder Kubota diesel engine (meets emission standards including EPA Tier 4 and EU Stage 3A) with 36.5 KW / 50 HP. The maximum torque of the 2.6 litre TDI engine is 170 Nm at 1600 rev / min at maximum speed of 2700 rev / min.
