Understanding pump efficiency starts with knowing where you are on the pump curve. But OEM (original equipment manufacturer) pump curves - while useful - don't always match what's happening in the field. That mismatch can throw off energy insights and decision-making.
With our latest update, SAM4 now supports calibrated pump curves based on telemetry - giving you a much clearer picture of pump performance and efficiency.
Real-world performance, not just specs
SAM4 now lets you:
- View actual pump head and flow performance based on historical telemetry
- Toggle between OEM and calibrated curves directly in the dashboard
- Get more accurate calculations of the Best Efficiency Point (BEP)
This helps operations and energy teams:
- Validate how well a pump is performing relative to real-world conditions
- Spot pumps that are chronically off-curve and wasting energy
- Build stronger business cases for replacement or reconfiguration
"OEM curves are a good starting point - but they're not the full picture. This update gives our customers a real, data-backed view of pump performance," said Gianlucca Frasso (Lead Energy Efficiency Analysis at Samotics).
OEM documentation pump curves show what's expected. Calibrated pump curves show what's really happening. By comparing the two, SAM4 reveals how pumps actually perform in the field - turning assumptions into actionable insights.
How it works
When telemetry is available (head & flow), SAM4 now overlays a calibrated curve that reflects observed pump behavior. This allows the system to:
- Detect shifts in pump performance over time
- Deliver more accurate energy insights (e.g., kWh/m³, BEP deviation)
- Improve prioritization of energy-saving recommendations
For customers without complete telemetry, this work lays the foundation for future estimation models using proxy data.
Available now
The calibrated pump curve feature is now live for supported pumps across all customers. It's already improving the accuracy of energy analyses in major water utilities.
