Advantages

  • Engineered and manufactured in-house to ensure end-to-end quality and assurance
  • Worldwide operating service network
  • Versatile product sizes and designs for almost all application areas
  • Maintenance-free
  • Internal volume and pressure compensating motor design for high operational safety and reliability in extreme installation depths
  • Minimal noise emission
  • Protected against vandalism
  • Flood-proof (IP68) and frost-proof
  • Environmentally friendly
  • Easy installation without complex adjustment or alignment work

Applications

  • Mining (dewatering and water supply)
  • Process pumps
  • Crude oil export pump
  • Pumping of refinery products like diesel, gasoline and liquid gases like LPG (Propane, Butane) and LNG 
  • Cavern storage of crude oil and refinery products
  • Leak water pumps for caverns
  • Offshore und onshore
Our leak water pumps for caverns operate continuously below the oil or water surface removing the leak water. The explosion prove design including the cables make them the ideal solution for caverns.
