EuroFlo at CrossRail

The EuroFlo Industrial Pump system retains Tunnel boring machine (TBM) cool by a steady water provide. The Cross Rail project is an east-west rail route that passes beneath town of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are positioned at the floor; the water is pumped from there right down to the shaft and all alongside the tunnel up to the TBM. Once the water has handed by way of the TBM system the remaining water comes back 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. pressure gauge 2.5 นิ้ว 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 tools 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 significant underground section of the Cross rail challenge.
