The PuraLev® 2000 Single-Use pump is 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 pump head is made of gamma stable polypropylene that meets the highest biocompatibility requirements such as FDA, USP-VI, and BSE/TSE free. The pump head is disposable and can be exchanged in few seconds. Fluid flow rate and pressure are precisely controlled by electronically regulating the impeller speed.
Proven by industry experience – The most gentle pump technology within bioprocessing!
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.
Maintain your liquid purity
Because of the low shear factor plus no wear or mechanical contact between moving parts, particle generation is eliminated, maintaining the purity of your liquid.
No more tube ruptures
Set and limit the maximum pressure according to your tubing specifications, and you rest assured your media is safe no matter what occurs in your hydraulic flow path.
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).
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.
No tubes to wear out or diaphragms to break
The 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.
Extremely high reliability
There 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.
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.
From a few mlpm up to max flow
PuraLev® 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.
Create a feedback loop
Integrate 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.
Up to 140 lpm / 37 gpm
In comparison to positive displacement pumps, there is a continuous discharge of liquid resulting in high flow capabilities at a small footprint.
No particle agglomeration
PuraLev® pumps have the unique capability to deliver solid-liquid mixtures without particle agglomeration or pump wear out.
