The features of the ROTAFLOW Centrifugal Pump include a peg-top, one-point sapphire bearing to lowers friction and optimized flow ratio with zero stagnant zones due to it's spiral housing. The ROTAFLOW Centrifugal Pump considerably reduces hemodilution and is ideal for both standard procedures and for high-performance situations.
