Levitronix PuraLev Single Use Pumps

PuraLev Single-Use Pump Series

ESI Ultrapure offer the PuraLev 200SU, 600SU, 2000SU & the integrated i-series i30SU & i100SU Single Use Pumps. Low Shear-Force Pump design to fit the most Demanding Biotech and Pharmaceutical Single-Use Life Science Applications.  

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 bio-compatible (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. The pump casing is fabricated with Triclamp fittings and has aseptic seal design.

Save on your Energy Costs

The optimal match between pump speed and pump operating point ensures that you are always able to operate your pump at the point of greatest efficiency. This can result in significant energy savings compared to the typical throttling control of a fixed frequency pump.
