PuraLev® Single-Use Life Science Pump Series

Safe, Clean and Low Shear-Force Pump Design to Fit the Most Demanding Biotech- and Pharmaceutical Single-Use Applications

PuraLev® 2000SU (Single-Use)

Levitronix® has developed a revolutionary pump that has no bearings to wear out or seals to break. Based on the principles of magnetic levitation, the pump’s impeller is suspended, contactfree, inside a sealed casing and is driven by the magnetic field of the motor. The impeller and casing are both fabricated from biocompatible (FDA, USP-VI, ABSE/TSE free and Animal free) resins and together they make up the pumphead. A continuous flow rate and pressure are precisely controlled by electronically regulating the rotor speed, which eliminates any pulsation. With the lack of mechanical bearings plus the self-contained pump head design, the risk of contamination is drastically reduced. The absence of narrow gaps between the impeller and pump casing, plus the low-shear pump design also allows the gentle pumping of sensitive liquids. The pump casing is fabricated with Triclamp fittings and has aseptic seal design.

Applications

  • Pumping of shear-sensitive liquids and cells
  • Bioprocessing (for example perfusion)
  • Recirculation and transfer applications in bioreactors
  • Filtration
