EuroFlo at CrossRail

The EuroFlo Industrial Pump system retains Tunnel boring machine (TBM) cool by a steady water supply. The Cross Rail challenge is an east-west rail route that passes under the city of London using new twin-bore 21km tunnels.
EuroFlo pumps and the tanks are positioned on 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 via the TBM system the remaining water comes again through a filtration system to the tanks on the floor, out of the tunnel.
The water circuit provides 20 l/s to every TBM and eight l/s is used in the TBM for various works and 12 l/s returns to the tanks. pressure gauge ลม wanted ranges between 4 and 10 bar. On one site three TBM’s are working 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 another site, 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 via a major underground part of the Cross rail venture.
