Tunnel Boring Machine (TBM), is a large machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They can bore through anything from hard rock to sand. Tunnel boring machine is used as an alternative to drilling and blasting methods in rock and conventional "hand mining" in soil.

Our hose pumps are installed into the Tunnel Boring Machine to be the bentonite slurry pump or foam pump.

As a long-term & excellent supplier of the parts of TBM, our company invited to take part in the meetings about the technology research & development of the tunnel boring machine. With the development of the tunnel boring machine, our company constantly launches the new-design hose pump to meet the request of the customers. Recently, in the big diameter ф12.14m earth pressure balance tunnel boring machine researched by China, four sets of our RH76 hose pumps were installed.
