Rotary pulsation device

Devices using rotating rotors juxtaposed static stators for mixing liquids is well known in the art. A rotary pulsation device having a body, at least one rotor and one or more stators, in which the increased efficiency of the device is effected through the presence of ultrasonic vibrations generated by the bulk vibration of the rotors, stators, or both, the generation of the vibrations is a function of a combination of one or more of: the clearance between the rotors and stators which can be adjusted; turbulizing elements on the rotors, stators, or both; incisions on the rotors; slots in the rotors; and choke channels for controlling and directing recirculated flow within the device.
