WHAT IS CFD?
Computational Fluid Dynamics (CFD) is simulation software that models how fluids move through pump systems. At United Flo, we use CFD to analyze flow behavior, pressure distribution, and turbulence inside pump chambers and impellers - allowing us to optimize hydraulic efficiency before manufacturing. This digital testing eliminates trial-and-error prototyping and ensures every pump we design performs exactly as specified.

HOW CFD HELPS IN PUMP DESIGN
CFD allows us to test hundreds of design variations digitally and identify the optimal configuration for your specific application. We can simulate how fluid moves through different impeller geometries, predict head and flow performance across the entire operating range, and pinpoint areas of turbulence or energy loss. This means we deliver pumps with less than 5% deviation from predicted performance - no guesswork, no field adjustments.
Predictive accuracy: Performance curves validated before manufacturing
Optimized efficiency: Hydraulics tuned to your exact flow and head requirements
Reduced cavitation risk: NPSH requirements calculated and verified digitally
Faster delivery: No prototype iterations - we get it right the first time
Lower energy costs: Impellers designed for maximum efficiency at your operating point
CFD PREDICTIVE PUMP PERFORMANCE

CFD generates performance curves that show how a pump will behave under different conditions, like varying flow rates and pressures.
These curves help engineers:
Find the pump's most efficient operating point.
Detect potential issues like cavitation or energy losses early in the design phase.
VISUALIZING PUMP CONTOURS: PRESSURE ANALYSIS

CFD creates detailed pressure contour maps that show how pressure changes throughout the pump as fluid flows from suction to discharge.
High-pressure zones indicate where the impeller is doing work efficiently, while low-pressure areas reveal potential cavitation risks or turbulence that could damage components.
By analyzing these pressure maps, we optimize impeller blade angles, volute geometry, and internal clearances to eliminate problem areas before the pump is ever built.
With the combination of CFD simulation and precision measurement of your existing system, United Flo delivers replacement pumps that are both custom fit to your installation and hydraulically optimized for your application. The result: better performance, longer service life, and zero modifications to your existing piping, mounting, or electrical systems.
