In most cases where boreholes are drilled in Africa it is to install hand pumps or solar pumps with a size smaller than 6" .For that reason on mud rotary holes we needed a 8" capacity and on DTH a 6" capacity. This is big enough to install water pumps.
The rig must be able to handle 6" PVC casing installations. Uses proven technology like the deutz F3L912 engine and even after long periods of drilling you can still keep your hand on the hydraulic tank.We have decided to use roque valves.
This rig uses 89mm drill pipes with 2 and 3/8 API IF threading. That reduces the friction in the case of mud rotary drilling as the internal joint diameter is 44mm.The drill tower is telescopic and uses earthalite blocks to reduce friction and is directly connected on the feed cylinder.The drill head is powered by a white drive product with 2200 Nm torque.So if you want a quality product that can drill up to 200mm holes.
The TWD200 drilling for groundwater can use air, foam or mud rotary for percussive drilling according to different textures. It is widely used in industrial and agricultural water conservancy projects, such as drilling wells, testing wells or other exploration boreholes.
In particular, in drilling hole for geothermal heating it can also meet the engineering basis for reinforcement,loose gravel drilling rock formation connected with a variety of engineering.
