Multi-stage Pumps

Multi-stage Pumps:

Simerics-MP+ can predict the head rise, pump power, pump efficiency, Net Positive Suction Head (NPSH), cavitation damage, parasitic losses, pump aeration, bubble formation, pressure ripples, pump leakage, axial loads and side loads in multi-stage pumps. (Testimonial)

Discriminators:

  • Models both free and dissolved gases
  • Models Cavitation
  • Superior speed enables transient simulations which are inherently more accurate
  • Can model the full range of operating conditions including shutoff
  • Superior treatment of rotating-stationary interfaces
  • Can include complex features and tight clearances
  • Ease-of-use

Design Issues/Benefits:

  • Predict performance to within 5 %
  • Determine the effects of aeration and cavitation
  • Analyze and reduce damage
  • Determine the required Net Positive Suction Head (NPSHr)
  • Predict loads
  • Predict leakage and parasitic losses
  • Reduce pressure ripple and noise
