Engineered with simplicity and sophistication, the ROTAFLOW Centrifugal Pump is one of the smallest centrifugal pumps available. It is a highly flexible modular component for systems integration.

The ROTAFLOW Centrifugal Pump is the only centrifugal pump without a metal shaft or seal. This pump features a peg-top, one-point sapphire bearing that lowers friction substantially. Its spiral housing ensures an optimized flow ratio with no stagnant zones. The Centrifugal Pump's minimal priming volume of 32 ml reduces hemodilution.

The ROTAFLOW pump head is the perfect choice - reliable and efficient for standard procedures as well as high-performance situations.

The ROTAFLOW Centrifugal Pump features:

  • Minimal priming volume
  • Minimal surface area
  • No stagnant blood zones and less hot spots
  • Minimal hemolytic index
  • Minimal MTT (Mean Transit Time)
  • Hydraulic optimized flow channels
  • Spiral housing for best flow ratio
  • Low-friction one-point bearing (sapphire ball & PE calotte)
