The PuraLev® 4000MU pump is designed for demanding fluid applications where ultra-low shear, 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 and 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. The reusable pump head is made of PFA / PEEK / Stainless Steel that meets the highest biocompatibility requirements such as FDA, USP-VI and BSE/TSE free.
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 which maintains the purity of your liquid.
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.
FDA, USP-VI and BSE/TSE free
All wet materials are fabricated from biocompatible (FDA, USP-VI, and BSE/TSE free) stainless steel 316L.
Multi-use pump head
The wet surface area can be cleaned with CIP or SIP.
Accurate, stable, and reliable flow 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, allowing for robust and safe processing.
Extremely high reliability
There are no bearings to wear out or seals to break down, increasing equipment uptime, 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 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.
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.
No particle agglomeration
PuraLev® pumps have the unique capability to deliver solid-liquid mixtures without particle agglomeration or pump wear out.
