EuroFlo at CrossRail

The EuroFlo Industrial Pump system retains Tunnel boring machine (TBM) cool by a continuous water supply. The Cross Rail venture is an east-west rail route that passes under the city of London utilizing new twin-bore 21km tunnels.
Secrets and the tanks are situated at the floor; the water is pumped from there down to the shaft and all along the tunnel as much as the TBM. Once the water has passed through the TBM system the remaining water comes again by way of 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 within the TBM for different works and 12 l/s returns to the tanks. The inlet strain needed ranges between 4 and 10 bar. On one website three TBM’s are working and the pump system delivers 60 l/s, with the gear consisting of one single tank (3200m3) and one industrial pump used per tunnel. On another web site, the installation support’s the excavation with just one TBM with 20 litres/second and the water storage tank capability of 1100m3
EuroFlo use 37 kW vertical multistage Industrial pumps for the cooling system whereas the TBM excavates through a serious underground section of the Cross rail project.
