EuroFlo at CrossRail

The EuroFlo Industrial Pump system retains Tunnel boring machine (TBM) cool by a steady water provide. Backed is an east-west rail route that passes underneath the city of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are located at the floor; the water is pumped from there down to the shaft and all alongside the tunnel up to the TBM. Once the water has passed by way of 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 eight l/s is used in the TBM for different works and 12 l/s returns to the tanks. Stunning wanted ranges between 4 and 10 bar. On one website three TBM’s are operating and the pump system delivers 60 l/s, with the tools consisting of one single tank (3200m3) and one industrial pump used per tunnel. On one other website, 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 major underground section of the Cross rail project.
