Low Shear Design
Proven by IndustryThe magnetic levitation principle and pump design guarantee that no components come in contact with one another enabling a continuous and smooth flow that virtually eliminates all shear.

PuraLev® Single-Use flow controllers are designed for demanding fluid applications in bioprocessing where extremely low shear, a pulsation-free, and continuously controlled flow ensure the highest product yield. 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.

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).
Accurate, stable, and reliable flow and pressure 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.
Up to 17 lpm / 4.5 gpmIn comparison to positive displacement pumps, there is a continuous discharge of liquid resulting in high flow capabilities at a small footprint.
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.
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.
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.
