Levitronix Bearingless Pump System BPS-2000 High Pressure


The BPS-2000 pump system is a revolutionary centrifugal pump that has no bearings to wear out or seals to break down and fail. 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 the impeller speed without pulsation. Closed loop flow or pressure control is easy configurable with the usage of an additional pressure or flow sensor. Various system configurations are possible as explained in the following sections.


  • Max. Differential Pressure: 6.9 bar 100 psi
  • Max. Flow: 80 liters/min 21 gallons/min
  • Max. Liquid Temperature: 90 °C 194 °F
  • Wet Materials: PFA / PTFE / Perfluoroelastomer
  • Supply Voltage: 2 kW / 1 or 3 x 200-240V AC


  • Extremely low particle generation due to the absence of mechanically contacting parts
  • Increased equipment uptime
  • Lower maintenance costs by eliminating valves, bearings, rotating seals and costly rebuilds
  • Reduced risk of contamination due to the self-contained design with magnetic bearings
  • Very gentle to sensitive fluids due to low-shear design
  • No narrow gaps and fissures where particles or microorganisms could be become entrapped
  • Smooth, continuous flow without pressure pulsation
  • Electronic speed control
  • Compact design compared to pneumatic and mag-drive pumps
  • Proven technology in medical and semiconductor industry (MTBF > 50 years)
