DOP Pump 250 with leveller head

Confined spaces are the right challenge for the DOP250.

The German city of Hamburg is working on its public transport infrastructure. The expanding city’s underground network, or “U-bahn” as called in German, required the construction of a tunnel. The tunnel site consists of sheet piles at either sides with heavy steel beams at regular intervals. This construction results in a very small operating area. The solution to the required bed leveling was using a DOP Submersible Dredge Pump 250. The 195 kW hydraulically driven DOP250 was attached to a crane, running on it’s hydraulic power.
