Abstract

An impeller includes a hub and a plurality of blades. Each blade extends out from the hub. The impeller has an original diameter defined by respective tips of the plurality of blades. Each blade includes a central axis, a leading edge, a trailing edge, an original profile, and a plurality of trim profiles. The original profile has an outside portion and a trailing portion. The outside portion has an angle within a range of about 40degrees to about 90degrees from the central axis and the trailing portion having an angle within a range of about 10 degrees to about 50 degrees from the central axis. A first selected trim profile of the plurality of trim profiles extends along a first line parallel to the outside portion and a second line parallel to the trailing portion.

Description

technical field [0001] The present disclosure generally relates to an impeller. More specifically, the present disclosure relates to base impellers configured to be trimmed to a plurality of different diameters. Background technique [0002] It is generally known that impellers are used to keep fluids mixed and / or particles suspended (when stored in containers). Typically, the impeller is placed relatively close to the bottom of the vessel to aid in mixing and to allow mixing when the vessel is empty. Based on a number of factors, it may be advantageous for impellers to be available in a range of sizes. Examples of factors that may affect the diameter of the impeller may include, for example: the volume of fluid to be mixed; the shape of the mixing vessel; the size of the opening in the vessel; the speed and / or torque rating of the motor rotating the impeller; viscosity; particle size and / or total volume of the fluid to be mixed, etc. However, it may not be cost-effectiv...
