FEDCO MSD-650 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 in Super Duplex stainless steel throughout, built to order for seawater and brackish-water reverse osmosis, produced-water recycling and industrial process duty. The patented FEDCO Water Bearing™ carries the full hydraulic thrust load so none reaches the motor, and the pump runs with no oil or grease anywhere.
