Impeller & Propeller

 · A propeller is an open running device - its function directly is creating the effect (usally a thrust force --> where the word propelling is derived from and which might be one reason of confusions). Sometimes you see a propeller surrounded by a short tube. Now it becomes difficult to decide whether we have an impeller or an propeller.

What is Difference between impeller and propeller?

An impeller as in a pump, moves the fluid, not the thing to which it is attached. One moves the thing to which it is attached, and the other moves the fluid that flows through it. Impeller is used in the pump for pump the water. Propeller is used in ship and air craft for to get the motion. The right answer is that difference of shape...

Types of agitators

2018-4-2 · 5. (1) Paddle Agitators: This is one of the most primary types of agitators with blades that reach up to the tank walls. Paddle agitators are used where an uniform laminar flow of liquids is desired. (2) Anchor Agitators: This simple agitator consists of a shaft and an anchor type propeller and can be mounted centrally or at an angle.

Propeller Fan

Propeller Fans. The propeller fan is a comparatively simple form of a fan with a sheet metal, 3–6 bladed impeller directly driven by a motor mounted in the airstream. Efficiencies up to 75% can be achieved, though pressure development is low and overloading can occur if the fan is installed in a system with too high a resistance.

Types of Impeller Blades | Norstone Inc.

The propeller blade or marine-type impeller blades work well with low to medium viscosity mixtures. They are modeled after the propellers on marine boats. They are used mostly in smaller, portable direct drive mixers because they are efficient and economical. The marine-type impeller blades have a medium shear with medium to high mixing intensity.
