The Levitronix® BPS First Generation pumps are designed for ultrapure processing of delicate fluids in microelectronic wet applications. Based on active magnetic levitation, the pump impeller is suspended and driven by the magnetic field of the motor. The wide gap ensures that there is no mechanical contact between moving parts and therefore no wear. There are no bearings to wear out or seals to break down.The impeller and casing are both made from chemical-resistant high purity fluorocarbon resins. Fluid flow rate and pressure are precisely controlled by electronically regulating the impeller speed.

Levitronix® BPS pumps offer distinctive advantages in microelectronic wet applications that will improve your product yield.

Benefits

The Purest Pump

Proven by industry experience - The purest pump within semiconductor manufacturing (and beyond)!

Since there is no mechanical coupling between the impeller and the pump head casing, there is no wear and therefore virtually no particle generation.

Very Low Trace Metal Contamination

Significantly lower than air-operated pumps

The wet surface area of a Levitronix® pump is several times smaller than in comparison to pneumatic pumps of comparable hydraulic power.

Low Shear Design

Ideal for Slurry and delicate plating liquids

The smooth wetted plastic surfaces and the absence of a mechanical bearing, narrow gaps, fissures and dead-zones allow for gentle processing of sensitive liquids.

Pulsation Free Flow

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 pulsation-free flow.

No more flow throttling – highly accurate flow and pressure.Due to its variable speed and high resolution, the Levitronix® pump allows precise control of flow or pressure over a wide operating range.

High Controllability and Wide Flow Range

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.

Highest MTBF (>100 years)

Widest flow range – From ultra low flow to maximum flow.The high speed and resolution of a Levitronix® pump allows to control and maintain the flow from a few ml/min up tothe maximum flow rate.

Highest Turndown Ratio

Substantially smaller than air operated pumps.The highly integrated design of the pump and motor combined with the absence of a mechanical bearing results in a system that greatly reduces the space requirements and allows for installation in confined spaces.

Small Footprint

More than 25 years experience. Levitronix® pumps are firmly established in highly demanding industries beyond semiconductor manufacturing such as biopharmaceuticalproduction.

Long History

Smart Pumps for Smart Manufacturing. Levitronix® pumps allow high-performance data acquisition, ideal for predictive maintenance and for factory wide system integration.

Constant Data Acquisition and Condition Monitoring

Substantially less noise than with pneumatic pumps.Since there is no mechanical coupling of the impeller and the pump casing, the pump produces virtually no vibrations resulting in a very quiet operating pump system.

Low Noise and Low Vibration
