LH-W | 3-phase / 50Hz

The recent developments of civil engineering and architectural technologies are increasing the necessity of digging deeper into the earth. This requires a submersible pump with a rugged construction that can withstand the high pressure so deep in the water.

Recycling water is needed to cool the residual slag. The mud-laden water must be pumped by high-pressure drainage pumps through a sprinkler system over the still-hot slag. The sprinkler system requires a pressure of about 3 to 4 bar.
