Akkerman Inc.

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.
