Masterflex® Sealless Centrifugal Pumps

Experience up to 70% operating efficiency in addition to greater reliability compared to sealed pumps
  • 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 polypropylene magnetic drive centrifugal pumps feature carbon bushings that allow extended run-dry ability. The NPT connections ensure easy installation into your piping system (50 Hz versions have BPS connections). The modified concentric volute minimizes radial loads and distributes pressure evenly across the entire flow range for improved reliability. 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.

Note Some models are available with or without motor. See tables below for details. If there is not a RPM filled in the below table, it is a model that comes without a motor. The ones with 2900 RPM mentioned are the 50 Hz versions.
