Pump Impeller I Application Guide I SimScale Simulation Hub

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..

Typical Pump Impeller Types Include:

Pump impellers can be applied in a variety of scenarios, and exist as 3 main types that are then used in turbomachinery systems:

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 simulated and evaluated early in the design process to determine the optimal design. However, the high cost of hardware and steep learning curves of traditional, on-premises tools leave many designers to feel that simulation is not an option.

SimScale has eliminated such barriers , thanks to the power of the cloud. With SimScale, engineers can:

- Run multiple simulations in parallel for faster design optimization
- Get started quickly with an easy-to-learn interface
- Avoid manual updates, installation, or maintenance
- Simulate other CFD, FEA, or thermal applications
Using CFD simulation from SimScale, designers can evaluate parameters of interest, such as 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. Additionally, SimScale offers thermodynamic analysis that can benefit engineers dealing with specific heat parameters within their application.
