Flow simulations for obtaining world-class energy efficiency
Simulation provides accurate insight of flow/velocity, pressure and hydraulic losses.
UNDERSTANDING COMPLEX FLUID-FLOW IN PUMPS
Fully automated design process and high-end optimization techniques ensures world class efficiency and produceability.
ENERGY EFFICIENCY VS MANUFACTURING
Flow simulations for obtaining world-class energy efficiency
Flow simulations are used by the hydraulic designer to predict and reduce forces and vibrations resulting from e.g. one-channel impellers in waste-water pumps
HYDRAULIC FORCES AND VIBRATIONS
Flow simulations for predicting forces and vibrations
Flow simulations for predicting cavitation
Baseline design Improved design
Flow simulations are used in the hydraulic design process to minimize cavitation and enhance low-NPSH performance
CAVITATION PREDICTION
Flow simulations are used to predict sand wear on hydraulic components. This allows the hydraulic designer to optimize the geometry and maximize life time
SAND WEAR PREDICTION
Flow simulations for predicting sand wear in waste-water pumps

SIMULATION DRIVEN DEVELOPMENT
SIMULATION TYPES
Concept Simulations Used to compare and contrast, sometimes radically, different concepts. The simulations can be used to lay out initial requirements and constraints for the design phase.
Design Simulations Used to drive detailed design decisions and ensure that the design conforms to requirements and constraints.
Verification Simulations Used to verify that designs conform to requirements.
