Abstract
An apparatus and method for a centrifugal pump for pumping sensitive biological fluids which includes (i) an integral impeller and rotor which is electromagnetically supported and rotated, (ii) a pump housing and arcuate passages for fluid flow and containment, (iii) a brushless driving motor embedded and integral with the pump housing, (iv) a power supply, and (v) specific electronic sensing and control algorithms--all fitly joined together to provide efficient, durable and low maintenance pump operation. A specially designed impeller and pump housing provide the mechanism for transport and delivery of fluid through the pump to a pump output port with reduced fluid turbulence.
