In Finland, as a by-product of mining operations, Gypsum is produced and utilized as a soil enhancer and for water conservation. The customer's objective was to maintain a dry environment in this area and effectively manage on-site water removal.
Skanska, one of the largest construction groups in the world, was looking for reliable pumps for a water cavern project.
New shafts were being excavated for the expansion of the underground mine in Serbia. Contractors in charge of the project used submersible pumps of other brands but had very bad experiences with too short lifespan of the pumps due to the heavy abrasive medium that has been pumped.
In Sweden, a company had issues in one its main production processes: heating extracted ore to extremely high temperatures, just shy of its melting point. Following this heating process, the ore undergoes cooling. During the process residual water needs to be pumped which can be a challenge as well. The temperature of the residual water reaches up to 60 degrees celcius. As an added hardship the water is also loaded with abrasive ore particles.
A large open pit coal mine used to install dewatering pumps from European manufacturers and had issues with pumping water during heavy rain events and snow season when the water became mudy and loaded with solids. When the water became loaded with abrasive material a lot of problems started.
An open-cast mine in Cyprus produces extremely acidic seepage water with a pH value between 2 and 3. Pumps from different manufacturers only lasted two weeks to a maximum of three months in test operation. Therefore they were looking for a mobile submersible pump that would function permanently under the extreme conditions and be as maintenance-free as possible.
