CASE STUDIES

Copper Mine, Nikosia, Cyprus

In one of the largest open-cut copper mines in the world, water is found with a pH value of 2 to 3. This must be pumped out. Numerous pumps from the competitors have already been tested, but have only achieved service life of two weeks to a maximum of three months.

RWE Brown Coal Open-Cast Mine, Inden, Germany

Pumping surface water from the main level of the Inden open-cast mine into the receiving body of water.

Mine in Oberwiesenthal, Germany

Water penetrates the top of the mining shaft, washing away many sediments with a diameter of 0.1 mm to 0.2 mm. Both competitor pumps and hoses quickly wear out under these conditions; the previous pumps had to be replaced approx. every six months.
