Pump & Impeller simulation software
Pump Impeller CFD Simulation. Cavitation, Head & Efficiency in the Cloud
Predict cavitation, generate head-flow curves, and validate efficiency for closed, semi-open, and open impellers — entirely in your browser, with no hardware or IT setup.
Cavitation risks, efficiency drops, and long prototyping cycles make pump impeller development slow. SimScale removes the bottleneck. Run impeller variants in parallel, assess NPSH margins, and lock in a design before metal is cut.
Why SimScale for Pump Impeller Simulation
Multiphysics One platform,
CFD and FEA. Run pump-curve CFD, NPSH and cavitation analysis, and impeller blade stress on the same geometry. No file export. No second tool.
AI-accelerated
AI-assisted workflows. Mesh generation, setup, and post-processing analysis accelerated so you can iterate dozens of impeller variants without specialist CFD support.
Cloud-native scale
Cloud Cloud, parallel, instant. Run 20+ operating points concurrently. Get a full head-flow-efficiency curve in two hours, not two weeks. No licenses, no workstations, no queue.
Centrifugal impeller pump curve
Generate head, shaft power, and efficiency vs flow rate across the operating envelope using SimScale's turbomachinery-specific Multi-Purpose solver with full cavitation modelling.
NPSH and cavitation analysis
Diagnose cavitation onset, locate vapour pockets on the suction side, and quantify efficiency drop before field deployment.
Closed, semi-open, and open impeller selection
Compare closed (high pressure, viscous fluids), semi-open (HVAC, water supply), and open (solids-handling) impeller geometries on identical operating conditions.
2 hrs
to generate full pump curve (down from 2 weeks)
“I've run simulations of almost every type of pump I've designed over the past 40 years. The insight obtained from CFD simulations in SimScale is like looking inside a transparent machine using a laser doppler velocimeter. It is priceless!”
— Industrial Engineer and Designer, Guerriero Romani
100x
faster simulation turnaround
“SimScale drastically changed our R&D landscape regarding time (99.9% quicker), cost (no HPC and data storage) and simulation accuracy. It allows us to complete development cycles within days instead of months — which gives us a massive advantage over our competition.”

Yes. SimScale's Multi-Purpose solver includes a full cavitation model. You can predict vapour pocket formation on the suction side, quantify the associated head and efficiency penalties, and determine NPSH margins — all without specialist CFD knowledge.
Set up a parametric study with multiple flow-rate operating points and run them in parallel on the cloud. SimScale extracts head, shaft power, and hydraulic efficiency at each point automatically, so you can assemble the full performance curve in a single session.
SimScale supports closed, semi-open, and open impellers, as well as volute and diffuser casings. Axial, mixed-flow, and centrifugal configurations are all supported. Self-priming, submersible, and pump-as-turbine setups can also be modelled.
SimScale's turbomachinery solver is validated against published impeller test data. Accuracy depends on mesh resolution and the operating conditions modelled; our validation library includes centrifugal pump cases you can use as a reference baseline before starting your own study.
No. SimScale runs entirely in your browser on shared cloud infrastructure. AI-guided setup — including automatic mesh generation and boundary condition suggestions — means design engineers without deep CFD backgrounds can run impeller simulations independently.
