  • Bioprocessing Flow Controllers

PuraLev® Single-Use flow controllers are designed for demanding fluid applications in bioprocessing where extremely low shear, 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.

The PuraLev® Single-Use flow controller offers distinctive advantages to the bioprocessing industry that will improve your product yield.

Benefits

Low Shear Design

Proven by Industry

The magnetic levitation of the pump impeller enables a contact-free operation and a low shear design for gentle pumping of sensitive liquids like cells, proteins, and LNP’s.

The Purest Pump

Maintain your liquid purity

The low shear factor and the lack of wear or mechanical contact between moving parts eliminate particle generation and maintain the purity of your liquid.

Intrinsically Safe

No more tube ruptures

Set and limit the maximum pressure according to your tubing specifications, and rest assured 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 Robust
All 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 and pressure for your process
The open pump head design, high flow resolution, centrifugal pump principle, and the absence of valves lead to a completely pulsation-free flow.

Completely Pulsation Free

Up to 17 lpm / 4.5 gpm
In comparison to positive displacement pumps, there is a continuous discharge of liquid resulting in high flow capabilities.

 

High Flow Capabilites

From a few mlpm up to max flow
PuraLev® pumps can accurately control and maintain a smooth flow from just a few mlpm up to the maximum flow rate, giving them the highest turndown ratio among competitive pumps.

Highest Turn Down Ratio

Significantly smaller footprint than positive displacement pumps
All PuraLev® pumps have a much smaller footprint than competitive pumps of comparable hydraulic performance. The magnetic bearing also eliminates any noise generation from your process.

Small Footprint, Low Noise Generation

No tubes to wear out or diaphragms to break
The magnetic levitation principle guarantees that no components come in contact with one another, allowing for robust and safe processing.

Ideal for Continuous Processing
