Pump station hydraulic design

What We Can Do:

NHC provides hydraulic analysis and design recommendations for operating pump station sumps and wet wells. Pump stations that operate with unsuitable approach flow hydraulics can suffer damage from cavitation, vibration, and bearing wear, and may be unable to meet design requirements. Focused analysis using physical and CFD modeling provides key information for optimal pump design, thus improving performance, reducing maintenance costs, and increasing the lifespan of equipment.

Our services may be applied to projects involving water supply, wastewater, stormwater, flood control, fire water, and power plant cooling water systems.

Experience & Services:

  • Physical Modeling
    NHC has conducted more than 200 physical model studies for new and existing pump stations including water, wastewater, stormwater, and flood relief pump stations across North America.
  • Numerical Modeling
    Our team uses CFD modeling, STAR-CCM+, FLUENT, and FLOW-3D to evaluate the approach flow to many pump stations for water, wastewater, flood relief, fire water, and industrial pumping projects.
  • Troubleshooting
    NHC's experienced professionals regularly troubleshoot pump station problems. Together with our outside vibration experts, we comprehensively analyze performance problems and develop feasible solutions.
  • Conceptual Design
    We prepare design reviews and conceptual designs for many engineering firms and project owners. Our work has been published in scientific journals and our membership on several design committees demonstrates our capability to develop dynamic designs and troubleshoot pump performance problems at an early stage.
  • Capacity Optimization
    We use physical modeling as a design tool to maximize station flow capacity. Simple modifications can be made that significantly increase capacity of pump approach flow, thereby eliminating or delaying major capital costs.

Technical Approach & Capabilities:

  • NHC operates four permanent physical modeling laboratories and a variety of numerical models to assist in evaluating, designing, and troubleshooting new and existing pump stations.
  • We often use physical modeling to evaluate the design of large pump stations and diagnose pump station problems.
  • We primarily use CFD (3D numerical) modeling to assess the approach flows for larger pump stations, and to assist in the hydraulic design of smaller pump stations.
  • NHC experts serve on design committees and publish research in scientific journals.
