Optimal power utilization


Our focused product development combined with over 60 years of experience from thousands of applications has led to continuous improvements in our products. The benefits to customers are numerous but the most significant is the life time cost saving that will be achieved by using Orion horizontal slurry pumps.

  • High efficiency hydraulic design ensures optimal power utilization
  • Range optimization ensures operation close to the best efficiency point
  • Use of fluid dynamic software to improve pump hydraulic efficiency
  • Wear parts of highest quality hard metal, rubber and corrosion-resistant materials
  • Robust design with extra thick sections at known points of wear
  • Highest quality of wear resistant elastomers developed by Metso
  • Interchangeability of hard metal and elastomer parts to provide the best solution for each individual application



Specially developed features in our pumps provide trouble-free operation and a minimum downtime improving the cost effectiveness of the operation:

  • Oversized high strength alloy steel shaft is carried in heavy duty grease lubricated
  • bearings in a self-contained cartridge assembly
  • Double seal arrangement provides positive seal of bearings against contamination
  • Proven and reliable gland seal options to meet individual requirements, using expellers,
  • flushed glands or mechanical seals
  • Modular design and full interchangeability of parts minimizes stock levels
  • Back pull out feature allows ease of inspection and maintenance
  • Compact and functional design
