Water Jetting & Cooling
The SC‐115 High‐Pressure Jetting Pump provides high velocity jetting through jetting lines in the tunnel. The jetting travels to the cutter face to break down clay and silty spoil, clean the crushing chamber, and clean the cutter face for efficient spoil intake and flow in the slurry lines.
The Water Cooling Tank provides ample supply to cool the MTBM drive and booster pump motors and flushes seals for optimal system operation. The cool water flow also assists with temperature reduction in the tunnel, contributing to guidance system laser clarity. Water from the Water Cooling Tank, through a jacking frame valve, hoses in the tunnel and concludes the MTBM motor. The Water Cooling Tank assembly includes an electric variable speed, variable output, smart tank sensor, and digital readout of output flow.

Testimonials
Lithos Engineering is focused on providing tunnel design and construction management for underground construction projects across the United States and has worked with many different tunnel contractors on projects of varying sizes and complexity. I am always happy
to see Akkerman equipment on our project sites and I know we can rely on Akkerman products for a high level of performance and reliability.
I had the pleasure of working with Akkerman on one of our projects for which they designed and constructed a project specific hard rock TBM for a curved water conveyance tunnel high in the Rocky Mountains of Colorado. Akkerman not only provided great solutions and technical support for the project but was a pleasure to work with in a collaborative teaming environment that allowed us to not only reduce project risks but reduce construction costs and schedule. During that project, I visited the Akkerman production facility to inspect the TBM under construction; I was extremely impressed with the Akkerman management, staff, and systems for quality control. I look forward to a long future of working with Akkerman and their products on our tunneling projects.
