Abstract
A pump assembly having a mounting arrangement which minimizes or eliminates bending stresses which may cause grinding between the pump rotor and its housing includes laterally spaced legs extending from the pump housing at a location adjacent to the end opposite the end coupled to the drive motor. The undersurface of each leg includes a surface upon which the assembly may pivot. Furthermore, the motor is fastened to a support plate at a single point, while another mechanism in combination with that connection prevents relative rotation between the motor and the support plate.
