Impellers vs. Propellers
Feb 22, 2017

Impellers appear very similar (or even identical) to propellers, and the two are often used interchangeably in the fluid power industry. Indeed, the two base terms involved — propel and impel — are both defined as "driving or moving forward." In industrial applications, however, the two are used to describe two different devices which drive two different objects or substances.

Propellers commonly refer to devices which move an attached object. For example, a ship's propeller moves the ship itself forward or backward. Impellers, on the other hand, are designed to move the substance — fluid or gas — passing through it without moving the object it is attached to.
