  • Selecting Pumps for Mining Applications Pumps & Systems

    Considerations For Proper Mine DewateringUnderground Applications & Submersible PumpsAboveground Applications & Self-Priming PumpsMetallurgic CompatibilityThis article focuses on mine dewatering. Proper mine dewatering is a critical component to every successful mining operation, regardless of the type of mining that is being done. If the pumps used for dewatering are too small or there is an insufficient number of them, there is a possibility of being flooded out and losing critical equipment and operational time. Conversely, if the selected dewatering pump is too large, the motor could burn on See more on pumpsandsystems
