The PuraLev® 4000MU pump is designed for demanding applications in bioprocessing. Based on active magnetic levitation, the pump impeller is suspended and driven by the magnetic field of the motor. 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. 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 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.
Multi-use pump head
The wet surface area can be cleaned with CIP or SIP. Additionally, the pump head is available with or without drainport.
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.
Up to 200 lpm / 53 gpm
In 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 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.
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 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.
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.
Significantly smaller footprint than positive displacement pumps
All 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 particle agglomeration
PuraLev® pumps have the unique capability to deliver solid-liquid mixtures without particle agglomeration or pump wear out.
