Water Jetting & Cooling - Akkerman


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.

Super Excavators, Inc. has enjoyed a long partnership with Akkerman over the years. We originally bought a competitor’s microtunnel system and had nothing but problems with quality and service. Finally we called Akkerman and bought their SL36 microtunnel system. Since then we have never looked back. We have bought several other pieces of equipment from Akkerman. From GBM equipment to ABIS to several microtunnel cutting heads. They have been great working with our staff to customize the equipment for our specific needs. We have put their equipment to the test on several projects by pushing the envelope in long drive distances and very difficult ground conditions. The equipment has responded well and together we have made modifications to continue to improve on efficiency. In our business it is necessary to have people their when you need them. Akkerman has done a great job at supplying quality equipment and servicing our needs in a timely matter, helping keep our work on schedule.
