More Information
Summary:A pump assembly includes a pump with a pump body having a discharge passage, a motor to drive the pump to discharge compressed air through the discharge passage, a casing at least partially surrounding the pump and the motor, and a motor mount at least partially supporting the motor within the casing. The motor mount includes an outer axial wall, an inner axial wall, a radial wall extending between the outer and inner axial walls, a first plurality of projections extending from the radial wall toward the motor, and a second plurality of projections extending from the radial wall away from the motor. The first plurality of projections is arranged in an annular array extending in a circumferential direction of the radial wall, and consecutive projections in the circumferential direction are spaced apart by a distance greater than a width of one of the consecutive projections.
