Carl Hamm ZSM in deep-well sinking

The ZSM Technology has been used for more than 20 years in German brown coal open-pit mining to manage the groundwater level. Especially in well galleries with a high amount of interconnected wells the advantages of the ZSM-connection are emphasized.

The frequent pump changes – due to high solids content of the pumped medium and the moving open-pit – can be executed much faster because of the very short assembly and disassembly times.

The low installation dimensions of the connection allow higher pipe diameters. As a result, lower velocity can be achieved at the same pump capacity by even enlarging the system effi ciency. Also this ensures a substantial extension of the service life of a pipeline and the pump used.

The ZSM Technology is also very popular for applications in irrigation projects with deep wells, especially due to the advantage of the low installation dimensions and short installation time and its resultant benefits.
