Case Studies
  • Pumping equipment in phosphate fertilizer processes
    Pumps are at the heart of phosphate fertilizer production, and correct equipment selection that takes into consideration hydraulic design, materials of construction, application knowledge, duty point and maintenance regime are critical to achieving reliable long-term pumping operation and maximum plant production.

  • Better performance and lower costs at a steel mill
    After years of changing new casings and propellers every three months to their process pump, a metal industry operator switched their worn-out pump to one of Sulzer’s EMW slurry pumps at their melt shop. The client considered the change a leap forward in their slurry pumping technology since the maintenance interval grew significantly, pump efficiency improved, and the change reduced power consumption.

  • Driving up efficiency
    The adoption of electric vehicles across the world is increasing rapidly and this demand needs to be matched by the supply of batteries. As new processing plants and manufacturing facilities are constructed, it is important that they employ the latest in pumping technology to ensure optimum reliability and efficiency. Read the article.

  • Expert solutions for mining and quarrying
    The mining, quarrying and construction industries present some of the most challenging applications encountered by pumps. The range of process fluids handled varies quite significantly across these processes, ranging from clear water to heavy slurries and from alkaline, pH neutral to highly corrosive fluids. As well as having to deal with the process requirements, products must also be compliant with the environmental and legislative constraints in play across geographies. Read the whole article.

  • Pump solutions for mine water management
    Mines require water. At the same time, because many mine working areas are below the water table, the removal of water is a major challenge. Water is critical for every mine site – without water the mine could not operate. Pumps are, therefore, one of the most used machines in mines today. In this article we will review the concepts of mine water and mine water management as well as the most common pumping applications. Read the whole article.

  • When faced with challenging process conditions
    Ma’aden Wa’ad Al Shamal Phosphate Company (MWSPC) is a leading player in phosphate fertilizers. Its complex in Umm Wu’al, Kingdom of Saudi Arabia, includes a worldclass phosphoric acid plant. Sulzer was selected to supply the gypsum evacuation booster pumps needed to evacuate gypsum cake resulting from the filtration of phosphoric acid slurry.
