- Closed Impellers The first, and arguably the most, rugged design is the closed impeller.
- Semi Open Impeller The semi open impeller is very similar in its design to the closed impeller.
- Recessed Impellers The third and slightly less common slurry impeller is the recessed impeller.
What are the different types of impellers? Impeller flow designs can take on three distinct types: axial, radial, and mixed. Because centrifugal pumps are also classified in this manner, the impeller selection depends upon matching the pump’s flow characteristic to that of the impeller. Axial flow impellers move media parallel to the impeller.
What is a closed impeller? Closed Impellers The first, and arguably the most, rugged design is the closed impeller. In this design, the liquid follows a path down a tunnel formed on the sides by the vanes and is “ closed ” in on the top and bottom (or front and back depending on shaft orientation) by two shrouds. The two images below illustrate this design.

What is the difference between an impeller and a propeller? An impeller is part of the centrifugal pump of the boat engine that sucks sea or lake water into the pump housing and circulates it for cooling. On the other hand, a propeller is a component that propels fluid or pushes water to move the boat in a particular direction. What is an Impeller on a Boat? How Does Impeller Work?
types of impellers
What are the types of pump casings and impellers? The impeller of a centrifugal pump can be of three basic types:
- Open impeller. Open impellers have the vanes free on both sides. Open impellers are structurally weak.
- Semi-open impeller. The vanes are free on one side and enclosed on the other. The shroud adds mechanical strength.
- Closed impeller. The vanes are located between the two discs, all in a single casting.
What are single impeller pumps used for? The single-stage centrifugal pump, consisting of one impeller, is the most widely used in production operations. They are used in pumping services of low-to-moderate TDHs. The TDH (total dynamic head) is a function of the impeller’s top speed, normally not higher than 700 ft/min. Single-stage pumps can be either single or double suction.

What impeller do I Need? Radial flow impeller types include:
- Radial Flow Anchor – An impeller designed for mixing higher viscosity products. An anchor is normally “U” shaped, and follows the contour of the tank.
- Radial Flow Paddle – Used for mixing. Impellers that convey the media outward to the side of the tank.
- Radial Flow Turbine – Used for mixing.
What are the different types of impellers?
What are the different types of pump impeller? Common Pump Impeller Types 1 Open Impeller Types. An open impeller has vanes that are attached to the eye or hub which at the same time is coupled to the pump shaft. 2 Semi-Open Impeller Types. 3 Closed impeller Type. 4 Vortex impeller Type. 5 Screw Impeller Type. 6 Chopper or Cutter Impeller Type.
What is an impeller in a mixer? The impeller is the component of a mixer that does the actual mixing and produces the results. That’s because when it rotates, it creates fluid flow and shear patterns. While there are many types of impellers, there are 4 main types we use when engineering mixers. 1. Airfoil
What is the difference between an open and closed impeller? An open impeller has vanes that are attached to the eye or hub which at the same time is coupled to the pump shaft. There is no shroud or wall surrounding the vanes front or back making open impellers more susceptible to vane failure than a closed or semi-closed impeller.
What is impeller design? Basic theoretical impeller design, showing the eye (shaft), vane assembly, and flow direction. Impellers are typically found in — and are integral components of — pumps, agitation tanks, washing machines, and other devices requiring fluids or gases to move in a specific direction.
