NOTE! The BPS-4 is part of the first generation of ultrapure bearingless pumps. For new applications, please visit the successor model BPS-2000 High Flow.
The Levitronix® BPS-4 First Generation pump is 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 fluoropolymer resins. Fluid flow rate and pressure are precisely controlled by electronically regulating the impeller speed.
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.
Significantly lower than air-operated pumps
The wet surface area of a Levitronix® pump is several times smaller than that of a pneumatic pump of comparable hydraulic power.
Ideal for Slurry and delicate plating liquids
The absence of mechanical bearings, narrow gaps, fissures, and dead zones combined with the smooth wetted plastic surfaces allow for the gentle processing of sensitive liquids.
Improved filter performance
The open pump head design, high flow resolution, centrifugal pump principle, and the absence of valves lead to a pulsation-free flow, thereby improving the performance of ultrapure filters.
No more flow throttling – highly accurate flow and pressure
The Levitronix® pump allows for precise control of flow or pressure over a wide operating range due to its variable speed and high resolution.
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.
From a few mlpm up to max flow
BPS pumps 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.
Substantially smaller than air operated pumps
The highly integrated design of the pump and motor combined with the absence of a mechanical bearing greatly reduce the footprint and allow for installation in confined spaces.
More than 25 years experience
Levitronix® pumps are firmly established in other highly demanding industries such as biopharmaceutical
Smart Pumps for Smart Manufacturing
BPS pumps allow for high-performance data acquisition that is ideal for predictive maintenance and factory wide system integration.
Substantially less noise than with pneumatic pumps
The magnetic coupling of the impeller and pump casing produces virtually no vibration resulting in an extremely quiet operation.
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.
