Class Information
Number: 417/423.1
Name: Pumps > Motor driven > Electric or magnetic motor > Rotary motor and rotary nonexpansible chamber pump
Description: Apparatus under subclasses 410.1+ in which the working members of both the pump and the motor perform their work by means of a unidirectional rotary motion; the pump working member acting to pump fluid by a centrifugal, centripetal or screw effect, i.e., not by positive displacement of the fluid by an expansible chamber effect.
