WEDA D40N Drainage Pump is used for various general dewatering purposes on construction sites. During construction, it is crucial to remove shallow water and groundwater to keep the project on schedule. Overall, the Atlas Copco D40N Pump is portable and easy to move from site to site.
Quarries require dewatering for a variety of reasons. In order to mine the aggregate for concrete and other construction materials, it needs to be sufficiently dry at the quarry. The D40N Pump can provide the dry sump needed for proper working conditions.
