Transcription de la présentation

  1. Revolution Centrifugal Pump Performance Overview Rev 2.1

  2. Centrifugal Pump Challenges • Bearing Failures • Leaks • Decouple • Noise & Fractured Magnets • Thrombus Generation & Hemolysis • Air Entrapment • Vane Impeller = Blender • Flow Sensor Issues • Ease of Set-up

  3. Designed by the experts in centrifugal pump design.

  4. Unique molded magnet driver: • Fills internal space • Assures balanced magnet • Consistent performance

  5. Pump Assembly Manufacturing Process • 100% Quality Control Process • Designed for manufacturability • Simple assembly • Minimal parts • Ultrasonic weld Assembly Simple Assembly = High Quality

  6. 1. Patented Curved Inlet Port 2. Patented Seal-less, Low Friction Upper Bearing 3. Patented “Spin-Inducer” 5. Ultrasonic Weld Upper & Lower Housing 4. Impeller floats while pumping Internal Features

  7. Flow Path 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.

  8. Pump-Head Internal Surface Area Revolution’s small surface area reduces platelet activation. Testing documented in Sorin Group Engineering Report SPN0263

  9. General Specifications data source: Manufacturers IFU

  10. Test Circuit 2 cc of air injected Volume collected in chamber

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