<p>An apparatus and method for a centrifugal pump (10) for pumping sensitive biological fluids which includes (i) an integral impeller and rotor (21) which is entirely supported and rotated magnetically by electromagnets (52, 54), (ii) a pump housing (12, 14) and arcuate passages for fluid flow and containment, (iii) a brushless driving motor (40) embedded and integral with the pump housing (12, 14), (iv) a power supply, and (v) specific electronic sensing and control algorithms-all fitly jointed together to provide efficient, durable and low maintenance pump operation. A specially designed impeller (21) and pump housing (12, 14) provide the mechanism for transport and delivery of fluid through the pump to a pump output port with reduced fluid turbulence.</p> |
