The EuroFlo Industrial Pump system keeps Tunnel boring machine (TBM) cool by a steady water supply. The Cross Rail venture is an east-west rail route that passes underneath the town of London utilizing new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are situated on the surface; the water is pumped from there all the method down to the shaft and all along the tunnel up to the TBM. Once the water has passed by way of the TBM system the remaining water comes back through a filtration system to the tanks on the surface, out of the tunnel.
The water circuit offers 20 l/s to every TBM and 8 l/s is used in the TBM for various works and 12 l/s returns to the tanks. Accessible needed ranges between 4 and 10 bar. On one website three TBM’s are operating and the pump system delivers 60 l/s, with the equipment consisting of 1 single tank (3200m3) and one industrial pump used per tunnel. On another website, the installation support’s the excavation with just one TBM with 20 litres/second and the water storage tank capacity of 1100m3
EuroFlo use 37 kW vertical multistage Industrial pumps for the cooling system whereas the TBM excavates by way of a major underground part of the Cross rail project.
