Tsurumi Europe’s LH and LH-W Series pumps have been developed specifically for pumping water in deep mines and chemically acidic environments.
In this situation, the pH value of the water is as important as the pump used. If the value falls below neutral, there is a risk of serious corrosion damage to the machinery. A pH value of around seven is considered neutral (in fresh water without CO2). Many dewatering water pumps struggle in acidic environments and Tsurumi is one of the few manufacturers which can supply pumps for pH values down to two.
The LH6110 pump has 110 kW motor power and can pump water up to 177 m vertically, achieving up to 3.000 l/min. As a submersible motor pump, it is also pressure-resistant to an immersion depth of 30 m.
If numerous mineral substances are found at the extraction site, the water takes on an acidic character. To deal with this, this series is built with austenitic stainless chrome-nickel steel with a molybdenum addition and uses the material DIN 1.4401, also known as AISI 316, offering higher resistance to the aggressive operating environment.
