Abstract
Disclosed are mechanisms for an impeller (10, 20, 40) and method of reducing noise levels while driving fluids with impellers. Exemplary implementations include a hub (21, 41) and multiple blades (22) separably attached to or inseparably formed on the hub. The hub may be used to effectively reduce noise levels during operations of the impeller by having a first cylindrical feature (261), a first number of first ribs (27, 47, 706), and a second number of second ribs (281, 48, 708), while maintaining substantially similar mechanical properties or operational characteristics. The hub may further optionally include a second substantially cylindrical feature (704) that is separably attached to or is inseparably formed on the hub to further enhance one or more properties or characteristics of the hub while serving to reduce the noise level of the impeller.
