Since decades the users of TOYO-heavy-duty-slurry-pumps value the good performance of it in the slurry-trench-wall application in the special heavy construction. In Germany nearly all notable building companies are using TOYO-pumps in the special heavy construction. 

In the last years the requirements in the slurry-trench-wall processing have grown. One reason for this is the risen pricing of land in the cities. This requires more constructions in the deepness for the maximum using of all levels of a building. Therefore slurry-trench-walls with a depth of more than 40 m are more common. For the exchange of the slurry in the trench-wall process TOYO developed the HD-version. These are types of the ET- and the DP-range with a surge tank. It is necessary for the pressure balance in sealing sector because the high atmospheric pressure in the depth of 40 m could damage the sealing and therefore cause the break-down of the complete TOYO-pump. The application of HD-version is not only limited to the special heavy construction but also to off-shore-services in the pipe-line laying.
