Pump Impeller

Application Guide from SimScale

A pump impeller, or simply an impeller, is a rotating component of a pump device. This rotor transfers energy from the motor that moves and accelerates the fluid outwards from the center of rotation.

What is a pump impeller

Typical Pump Impeller Types Include:

Pump impellers can be applied in a variety of use cases, and exisit as 3 main types:

  • A closed impeller where the vanes are in between 2 discs with closed casting
  • An open impeller that has free vanes on both sides
  • A semi-closed impeller where vanes are open on one side and enclosed on the other

Why Is Online Simulation with SimScale Needed for This Application?

A pump impeller needs to be e simulated and evaluated early in the design process to determine the performance of different pump impeller designs. Using CFD simulation from SimScale, you can evaluate parameters of interest like the pressure head and hydraulic efficiency. Users can also use FEA to test the stress and strain applied to pump impellers, as well as pressure from the water flow.
