Abstract: Maintenance-free pumps(MFPs) without moving parts are designed and developed for pumping hazardous fluids that are radioactive, high-temperature, toxic or corrosive. MFPs satisfy two criteria:(1) They should be capable of remote operation and control, and(2) There should be no moving parts(even electronic components) directly in contact with the hazardous fluid. Operating principles and performance for steam-pumps, air-lift pumps, vacuum operated slug lift pumps, diode pumps, forward flow diverter pumps(FFD pumps) and reverse flow diverter pumps(RFD pumps) are reviewed. Due to its excellent performance, RFD pump is preferentially presented.
