Geothermal drilling with the TERRA-DRILL

    For vertical bores for geothermical power


  1. Maximum drilling depth: 100-120 m (330-400 ft)
  2. The hydraulic power pack and the air compressor may be positioned up to 30 m (100 ft) away.
  3. Modular design of the drilling machine. This allows operation in smallest gardens.
  4. The low weight of the drill (2.1 tons/ 4’600 lbs) and the rubber crawler conserves the lawn.
  5. The transportation width of 0.95 m (37.4”) allows to drive through garden gates.
  6. “Air hammer method” or “mud drilling method” possible, therefore high productivity in nearly every ground.
  7. The duplex connector (“preventer”) allows simultaneous drilling of the casings OD 178 mm (7”) and the drill rods OD 89 mm (3.5”) with simultaneous removal of the drill mud into the mud container.
  8. The optional mud pump delivers 1’080 ltr/min (265gpm) Bentonite drilling fluid. The pump is also used for mixing of the Bentonite.
  9. The duplex piston pump is used for moistening the compressed air for the down the hole-hammer to increase the mud removal.
  10. Triplex clamping and break-apart system allows the hydraulic clamping and unscrewing of the casings and the drill rods.

Bentonite flush pump

    The TERRA-DRILL 4407 V can be used for „straight flush rotary drilling“. Therefore we offer an optional Bentonite flush pump with a separate hydraulic power pack.


    You can easily push both units to the jobsite. You can also lift them easily at their central lifting eyes into small front gardens.


    The power pack drives the Bentonite flush pump. The Bentonite flush pump is connected via large hoses DN 100 mm (4”) with the vertical drill and with the settling container (settling basin). The Bentonite flush pump delivers 1‘080 ltr/min (285 gpm) of a pressure of 3 bar (45 psi).
