Revolutionary Magnetically Levitated Centrifugal Pump

Levitronix® has developed a revolutionary centrifugal pump that has no bearings to wear out or seals to break. Based on the principles of magnetic levitation, the pump’s impeller is suspended contact-free inside a sealed casing and is driven by the magnetic field of the motor.

The impeller and casing are both fabricated from chemical resistant, high-purity fluorocarbon resins. Together with the rotor magnet they make up the pump head. Fluid flow rate and pressure are precisely controlled by electronically regulating rotor speed and eliminates pulsations.

Bearingless Pump Design

By eliminating a mechanical bearing, no mechanical friction occurs that could cause local hotspots. Moreover, no narrow gaps exist where metal other particles could precipitate. The low-shear, dead-zone-free pump design and the smooth, wetted plastic surfaces further aid in avoiding deposition in the pump.

Perfect Match to Your Flow and Pressure Requirements

Levitronix® bearingless pump systems all come with variable speed control so that the pump speed can be selected to optimally mach your operating point. Compared to mag-drive pumps which are operated with a variable frequency inverter, significantly higher speeds can be achieved since there are no limiting mechanical slide bearings. This feature allowed Levitronix® to design pumps with much higher pressure capabilities compared to mag-drive pumps. Levitronix® pumps are ideally matched to the typical pressure requirements of filtered recirculation loops. This provides you with the reserves needed to run your filters up to the recommended change out pressure with the added benefit of significant cost savings.

Save on Your Electric Bill

The optimal match between pump speed and pump operating point ensures that you are always able to operate your pump at the point of greatest efficiency. This can result in significant energy savings compared to the typical throttling control of a fixed frequency pump.
