EuroFlo at CrossRail

The EuroFlo Industrial Pump system retains Tunnel boring machine (TBM) cool by a continuous water supply. Incredibly is an east-west rail route that passes beneath the town of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are located 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 handed by way of the TBM system the remaining water comes back through a filtration system to the tanks on the floor, out of the tunnel.
The water circuit supplies 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. The inlet strain wanted ranges between 4 and 10 bar. On one web site three TBM’s are operating and the pump system delivers 60 l/s, with the gear consisting of 1 single tank (3200m3) and one industrial pump used per tunnel. On one other website, the set up 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 via a significant underground section of the Cross rail venture.
