FEDCO MSD-160 Multi Stage Duplex Pump
Manufactured by Fluid Equipment Development Company (FEDCO), Monroe, Michigan, USA — supplied by ForeverPure Corporation, an authorized FEDCO distributor based in Santa Clara, California.
The FEDCO MSD is a horizontal multistage centrifugal high-pressure pump engineered for seawater and brackish-water RO feed duty, with an industry-leading hydraulic efficiency up to 87% and FEDCO's patented Water Bearing™ technology that uses product water (no oil or grease) for thrust handling.
? Made to Order — Call for Availability
Each FEDCO pump is built to order at the FEDCO factory in Monroe, Michigan, sized to the customer's specific duty point (flow, pressure, feed TDS, recovery, materials of construction).
Typical lead time: 6–8 weeks (Super Duplex 2507) or 3–6 weeks (other materials). Call for current availability.

Theory of Operation
Multiple Super Duplex impellers stage the pressure rise from suction to discharge; FEDCO's Water Bearing™ takes the entire impeller-stack thrust load by using product water as a hydrostatic film, keeping the shaft in tension to eliminate buckling. Investment-cast Super Duplex internals resist chloride pitting and crevice corrosion. A removable mechanical-seal cartridge and rotatable inlet flange simplify installation and service.
Key Engineering Advantages
- Up to 87% hydraulic efficiency — among the highest in the industry for SWRO HP pumps
- Patented Water Bearing™ — no grease or oil to manage
- Investment-cast Super Duplex SS for chloride-rich service
- Balanced impellers and removable mechanical-seal cartridge for low maintenance
- Rotatable inlet flange and precision leveling feet for fast alignment
- Low-noise, smooth operation
