Levitronix®PuraLev®Low Shear Multi-UsePump Systems forBioprocessing

Levitronix® PuraLev® multi-use pump systems are designed for demanding fluid applications where ultra low shear, a pulsation free and continuously controlled flow eliminate any formation of particles resulting in a highly reliable solution. Based on the principle of magnetic levitation, the pump impeller is suspended, contact-free, inside a sealed casing and is driven by the magnetic field of the motor resulting in a continuous smooth flow. It combines all the advantages of a centrifugal pump but avoids problems related to the breakdown of mechanical bearings and seals found in competitive pump systems.

Levitronix® pump systems offer distinctive advantages to the bioprocessing industry that will greatly improve your product yield.
Benefits

Low Shear Design

Proven by Industry

The magnetic levitation principle and pump design guarantee that no components come in contact with one another enabling a continuous and smooth flow which virtually eliminates all shear.

The Purest Pump

Maintain your liquid purity

Because of the low shear factor plus no wear or mechanical contact between moving parts, particle generation is eliminated which maintains the purity of your liquid.

Intrinsically Safe

No more tube ruptures

Set and limit the maximum pressure according to your tubing specifications and you will be assured that your media is safe no matter what occurs in your hydraulic flow path.

Pressure Build-Up In Peristaltic Pumps

FDA, USP-VI and BSE/TSE free and Gamma RobustAll wet materials are fabricated from biocompatible (FDA, USP-VI, and BSE/TSE free) gamma stable (up to 40 kGy) polypropylene (PP).

Biocompatible Wet Material

Accurate, stable, and reliable flow for your processThe open pump head design, high flow resolution, centrifugal pump principle, and the absence of valves lead to a completely pulsation-free flow.

Pulsation Free Flow

No tubes to wear out or diaphragms to breakThe magnetic levitation principle guarantees that no components come in contact with one another which allows for robust and safe processing over a very long time.

Ideal for Continuous Processing

Extremely high reliabilityThere are no bearings to wear out or seals to breakdown, therefore equipment uptime increases, extending the life of your process equipment and reducing maintenance costs.

Highest MTBF (>100 years)

Significantly smaller footprint than positive displacement pumpsAll PuraLev® pumps have a much smaller footprint than competitive pumps of comparable hydraulic performance. The constant flow of these systems also eliminates any noise generation from your process.

Small Footprint, Low Noise Generation

From a few mlpm up to max flowPuraLev® pumps have the highest turn down ratio by being able to accurately control and maintain the flow from a few mlpm up to the maximum flow rate.

Highest Turndown Ratio

Create a feedback loopIntegrate a flow or pressure sensor into your pump system and create a feedback loop which will allow you to automatically maintain your desired process conditions.

Integrated Flow or Pressure Controller

No particle agglomerationPuraLev® pumps have the unique capability to deliver solid-liquid mixtures without particle agglomeration or pump wear out.
