Single Use Solutions - for Pharmaceutical and Biotech professionals

Levitronix® Puralev® unique single-use centrifugal pump.

PuraLev® i30SU (Single-Use)

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

Like all LEVITRONIX pumps the PuraLev-i30 pump is a revolutionary centrifugal pump that has no bearings to wear out or seals to break down and fail. 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. 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 impeller and casing are both fabricated from biocompatible (FDA, USP-VI, ABSE/TSE and Animal free) gamma sterilizable poypropylene (PP). The pump casing is fabricated with Barb fittings and has aseptic seal design.
