Revolution Centrifugal Pump
Performance Overview Rev 2.1
Bearing Failures Leaks Decouple Noise & Fractured
Magnets Thrombus Generation &
Hemolysis Air Entrapment Vane Impeller = Blender
Flow Sensor Issues Ease of Set-up
Centrifugal Pump Challenges
Designed by the experts in centrifugal pump design.
Unique molded magnet driver:
• Fills internal space
• Assures balanced magnet
• Consistent performance
Pump Assembly Manufacturing Process
100% Quality Control Process Designed for manufacturability Simple assembly Minimal parts Ultrasonic weld
Simple Assembly = High Quality
Assembly
1. Patented Curved Inlet
Port
3. Patented “Spin-Inducer”
2. Patented Seal-less, Low Friction Upper
Bearing
5. Ultrasonic Weld

Internal Features
4. Impeller floats while
pumping
Flow enters the inlet rinsing the top bearing
Centrifugal force moves fluid to the outside
Fluid not leaving the pump moves
back to the low pressure center,
rinsing the bottom bearing Recirculation is
completed by fluid moving up thru the central channel
As fluid moves up thru the central channel, it lifts the impeller off the bottom bearing, opposing the magnetic forces, reducing
bearing load and bearing friction. The impeller literally floats.

Computational Flow Dynamics
Large changes in velocity would indicate vortexing.
Note steady increases from center to end of vane tips.
