Technical Data

Levitronix® has developed a revolutionary Centrifugal 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, contact-free, 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 pump head. 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. This sanitary pump casing is fabricated with Tri-clamp fittings and has an aseptic seal design.

Stand-Alone System Configuration

The stand-alone configuration of the PuraLev Multi-Use Pump system consists of a controller with an integrated user panel allowing the operator to set the speed manually. The speed is automatically stored in the internal EEPROM of the controller.
