Simulation Software for Pumps, Motors, Compressors, Valves and Intergated Fluid Systems


PumpLinx® is a 3-D Computational Fluid Dynamics (CFD) tool that provides accurate virtual testing for the analysis and performance prediction of fluid pumps, motors, compressors, turbines, valves, and complete fluid systems with rotating/sliding components. For liquid systems, PumpLinx’s® proprietary Cavitation Module accurately models vapor, free gas and liquid compressibility to enable the analysis of performance, pressure ripple, and cavitation damage.
  • Comprehensive physics

    Flow, turbulence, conjugate heat transfer, aeration, cavitation, particles
  • Accurate predictions

    Excellent correlation with test data over the full operating range
  • Fast model creation, even faster simulation speed

    Less than an hour from CAD to simulation, < 15 min. for steady-state results
  • Able to model complex details down to the micro scale

    Accurately model leakage gaps, tip clearances, balance holes, etc.


PumpLinx® is built on Simerics® MP’s baseline technology to provide a transient 3-D simulation software uniquely suited for the analysis and design of pumps and other fluid devices with rotating or sliding components.
  • Result Accuracy

    Accurate Results:

    PumpLinx consistently provides simulation predictions that are within 5% of physical hardware test results over the full operating range. (Testimonial)
  • Cavitation

    Superior Cavitation/Aeration Module:

    PumpLinx rigorously and independently accounts for the formation, transport, and effects of non-condensable gases (e.g. air) and cavitation vapor, as opposed to using a lumped effective compressibility approach. (Testimonial)
  • Convergence

    Fast Calculation Times:

    PumpLinx has repeatedly been shown to be more than 10 times faster than other commercial codes, enabling more complex simulations, including full transient analysis when needed. (Testimonial)
  • Robust Solver

    Robust Solver:

    PumpLinx is able to converge extremely difficult problems, even those with detailed micro-scale features and/or severe cavitation. (Testimonial)
  • Easy of Use

    Ease of Use:

    Less than 30 minutes is typically required to create a model with the aid of templates, automated mesh generation and a single GUI for set-up, simulation, and post-processing. (Testimonial)
  • Support

    Virtually Unlimited Support:

    PumpLinx comes with extensive training and virtually unlimited support in helping set-up cases. (Testimonial)
