Bentonite Lubrication System

More effectiveness in pipe jacking thanks to direct bentonite control

• the initial injection directly next to the machine in order to fill the annular space, provide support and lubricate the pipe, and
• the subsequent injection into every third to fifth pipe in order to maintain and keep up the lubricant film that has been established.

• automatic volume-controlled distribution of the bentonite along the route
• quantities can be set for different underground conditions
• up to 4 bentonite supply lines and pumps can be controlled simultaneously
• all data saved (injection quantities, pressures, distribution, etc.)
• additional pressure sensor in the tunnel
• functional pipe sequence plan
• skin friction is displayed
