Masterflex® Sealless Self-Priming Magnetic Drive Centrifugal Pumps, PVDF

Lower cost of ownership achieved by reliable sealless pump technology
  • Superior lift capability lifts fluid from as deep as 25 feet below the pump
  • Fast priming—primes from 18 feet in as little as 90 seconds
  • Powerful, rare earth magnetic coupling uses standard NEMA (60 Hz) or IEC (50 Hz) motor
  • Greater efficiency translates into reduction in energy usage
  • High working pressure safely handles high specific gravity fluids
These horizontal, self-priming, PVDF magnetic drive centrifugal pumps offer many features which improve performance. The volute and impeller design allow for high efficiency, resulting in energy usage reduction, especially when compared to other established pump technologies. As a result of the high working pressure, high specific gravity fluids can be safely pumped. Another benefit is the protection against unexpected surges in system pressure. The standard NPT or BSP connections allow for easy installation. The wetted materials of construction were chosen and engineered for aggressive liquids.
Pumps feature carbon bushings that allow extended run-dry ability. The thrust balance system has generous balance holes and rear sealing ring to reduce axial thrust. The replaceable dual bushings ride evenly on the shaft for optimal alignment and reliability. The internal spiral groove helps to flush and lubricate the bushings during operation. PTFE bushings are the ideal choice for chemicals like sodium hypochlorite (bleach), chromic acid, chrome plating solutions, and nitric, chromic, and hydrofluoric acids.

Self-priming centrifugal pumps are extremely versatile. The priming ability allows the pumps to handle applications difficult for standard centrifugal pumps, such as pumping fluid from below grade, emptying tanker trucks or rail cars, and transferring fluids from the top of tall bulk storage tanks to reduce the possibility of leaks from sidewall-mounted bulkhead fittings.
