The ROTAFLOW Centrifugal Pump System offers state-of-the-art centrifugal pump technology for best performance and maximum safety.

The ROTAFLOW Centrifugal Pump System is a natural part of the HL 20 Heart-Lung Machine and can also be used as a fully independent stand-alone unit.


  • The ROTAFLOW Console operates independently as stand-alone with its own battery back-up and power supply.
  • It also perfectly complements the HL 20 product line.
  • Its compact design includes display for all vital information at a glance.
  • The unique flow and bubble measuring function is an integral part of the ROTAFLOW system.
  • Its compact design includes display for all vital information at a glance.

Integrated into the Heart-Lung Machine HL 20

  • The ROTAFLOW Console as HL 20 pump module, fully integrated into the Heart-Lung Machine HL 20.
  • In this configuration, all HL 20 supervising units will control and monitor parameters like pressure, bubble and low-level sensors.
  • The centrifugal pump operates quietly and smoothly on safe, low-voltage power supplied by the console.
  • There are no additional cables to connect.

Compact in size and low in weight

  • The ROTAFLOW Console is flexible: it can easily be removed from and reinstalled onto the HL 20, simply by lifting and positioning the unit according to guide pins.

Additional Features as HL 20 Pump Module:

  • Controlled by all supervising units (bubble, pressure, level)
  • Pulsatile flow mode option

One cable - three functions

  • The unique set-up of the ROTAFLOW Pump Drive also incorporates flow sensor and bubble detection into one advanced unit.
  • The blood flow is precisely measured in the pump outlet by ultrasonic transit time technology.
  • Costly disposable flow probes and time-consuming tubing connections are a thing of the past.

Optimum flexibility

  • The swivel-joint bracket assures ideal positioning with greater flexibility in handling, and allows shorter tubing lengths.
  • For further convenience, this sturdy drive's special cooling system has no dirtcatchingribs: a smooth surface for quick and easy cleaning.

The ROTAFLOW Emergency Drive

  • The emergency drive is designed for secure handling and fast fixation on the mast when every second counts.
  • While operating in manual mode, the LED displays the rpm
