Low Shear Multi-Use
Pump Systems for

Levitronix® PuraLev® multi-use pump systems are 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.

Levitronix® pump systems offer distinctive advantages to the bioprocessing industry that will greatly improve your product yield.

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

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.

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
All wet materials are fabricated from biocompatible (FDA, USP-VI, and BSE/TSE free) fluorocarbon resins or stainless steel 316L.

Biocompatible Wet Material

Multi-use pump head
The pump head can be cleaned in place (CIP), steamed in place (SIP) or autoclaved. Additionally, the pump head is available with or without a drainport.

Easy to Clean

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.

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.

Ideal for Continuous 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.

Highest MTBF (>100 years)

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

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 Turndown Ratio

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.

Integrated Flow or Pressure Controller

No particle agglomeration
PuraLev® pumps have the unique capability to deliver solid-liquid mixtures without particle agglomeration or pump wear out.
