An apparatus and a method are described for a versatile, multi-stage, centrifugal fluids-processing device adaptable to efficiently mixing, blending, emulsifying, deagglomerating or homogenizing fluids. Several beneficial features incorporated in the centrifugal-pump-type mechanism comprising an electric motor, an intake screen, an elongate metal body, a central drive shaft extending from the motor to the discharge end of the device. Attached internally to the drive shaft is one impellor per stage, which by rotation of the motor, imparts kinetic energy to the fluid being processed. The fluid discharged from the impellers passes through separate conduits and opposing commercially available nozzles, available for instance from spraying systems co., Wheaton, ILL., into opposite ends of a chamber having the internal shape of an oblate-spheroid with internally-ribbed ceramic walls. Said chamber (hereinafter referred to as the "Parr Chamber") is installed integrally within each impellor housing. Fluid passing through the nozzles gains velocity and kinetic energy as explained by "Bemoulli's Theorem". As a result of the high-velocity fluid streams approaching each other from virtually opposite directions within the Parr Chambers their kinetic energies are increased by approximately 400%; as a result of the incoming fluid streams being slightly divergent upon contact with each other they are mutually deflected at high-velocity and high turbulence to impact against the ribbed inner walls of the Parr Chamber in directions away from the outlet from said Parr Chamber. Said orientation of the incoming fluid streams aids in providing optimum use of the fluid's kinetic energy in turbulence and high-sheer contact prior to the fluids exiting said Parr Chamber. Fluid continually entering said chamber is processed and discharged into an internal conduit to the intake side of the succeeding impellor for repetition of the above process until discharged from the multi-stage device.
