EuroFlo pumps and the tanks are situated on the surface; the water is pumped from there down to the shaft and all along the tunnel up to the TBM. Once the water has passed via the TBM system the remaining water comes again through a filtration system to the tanks on the surface, out of the tunnel.
The water circuit offers 20 l/s to each TBM and 8 l/s is used in the TBM for different works and 12 l/s returns to the tanks. The inlet pressure needed ranges between four and 10 bar. On one site three TBM’s are working 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 one other website, the installation support’s the excavation with only 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 while the TBM excavates by way of a major underground part of the Cross rail project.
