An impeller is a rotor inside a pump through which the liquid flows to create a pressure gradient.
A propeller is used to propel a vessel.
In pump impeller liquid moves i.e. pump is stationary. In a vessel propeller the vessel moves through a liquid or gas!

What is the effect of changing the number of impeller blades?
Normally, by increasing number of vanes, curve shape becomes flatter and flow increases
What is the difference of an axial flow and centrifugal compressor?
The centrifugal flow compressor has a single or two stage unit using an impeller. The axial flow compressor is a multi-stage unit using alternate rows of rotating (rotor) blades and stationary (stator) vanes.
Why backward curved vanes are used in ordinary centrifugal pumps?
Back ward curved vanes only suitable for Better centrifugal force, because the pumping medium slip well when it rotating, because of centrifugal force pumping medium throw without restriction by impeller:
What is the difference between blade and vane?
A blade is a rotating airfoil, while a vane is a stationary airfoil. A set of blades is referred to as a rotor, while a set of vanes is called a stator. Compressors and turbines are comprised of alternating sets of rotors (blades) and stators (vanes).
How many vanes are in a body?
There are a lot of vanes in a human body. Everywhere you look on your body there probably will be vanes
What are different types of vanes used in centrifugal pump?
there are three major types vanes are used for a centrifugal pumps those are 1.forward curved vanes 2.backward curved vanes 3.flat vanes
What are the vane pumps?
A slotted rotor is eccentrically supported in a cycloidal cam. The rotor is located close to the wall of the cam so a crescent-shaped cavity is formed. The rotor is sealed into the cam by two sideplates. Vanes or blades fit within the slots of the impeller. As the rotor rotates and fluid enters the pump, centrifugal force, hydraulic pressure, and/or pushrods push the vanes to the walls of the housing. The tight seal among the vanes, rotor, cam, and sideplate is the key to the good suction characteristics common to the vane pumping principle.
Do airports have wind vanes?
Weather vanes, or wind vanes measure the direction of the wind. Airports generally have high tech instruments to measure the weather as opposed to regular weather vanes.
What is the weather vane collective noun?
There is no standard collective noun for weather vanes, most likely because weather vanes are seldom found in groups.However, a place that sells weather vanes might have a display of weather vanes or someone who loves all types of weather vanes might have a collection of weather vanes.
What is a sentence using the word vanes?
The weather vanes spun crazily. The bomb had vanes to make sure it landed nose first.
What is a structure called with revolving vanes?
A windmill is an example of a structure with revolving vanes.
When was Vanes Martirosyan born?
Vanes Martirosyan was born on 1986-05-01.
