MSD Series Feed Pumps

The FEDCO MSD Pump line emerged from the need of high efficiency combined with superior materials suitable for long term seawater service.

All investment cast stage components, highly refined flow path and the innovative water bearing technology make the MSD the “go to” pump for the most demanding SWRO applications around the world.


  • 20 – 1080 m3/h (88 – 4755 gpm)
  • Pressures to 82 bar (1200 psi)
  • All Super Duplex 2507 construction
  • Up to 87% efficiency


  • Patented Water Bearing Technology
  • All Super Duplex investment Cast Construction
  • Balanced Impellers
  • Rotatable Inlet Connection
  • Mechanical Seal Cartridge Easily Accessible
  • Precision Leveling Feet for Easy Alignment

Loaded with unique features such as the patented Water Bearing™ product lubricated bearings, Super Duplex stainless steel construction, and maintenance-free design ensure years of trouble-free operation. No need for several pumps in parallel, the MSD line has a pump feed flow capacity range of 20 to 850 m3/h and efficiencies up to 86%.
