Many pump users focus on efficiency ratings when purchasing new equipment, but a much greater source of wasted energy is found when looking at the overall system instead of limiting optimization to the pump design itself. It is rare that a system is operating with equipment that is optimized to deliver flow while operating close to its best efficiency point. More often, pumps are oversized for their systems and achieve the desired flow rate by throttling a valve. The friction added by this valve changes the system curve to achieve the design operating flow; this action is one of the greatest sources of wasted energy in a pump system. Continue reading

Resonant Mode Detected and Resolved in Critical Condensate Pump
A Midwest power utility customer was experiencing increased vibration after a refurbished Condensate pump was reinstalled on-site. They reached out to Hydro Reliability Services to help troubleshoot the vibration issue and determine if it was a problem inherent to the equipment or the result of the refurbishment. Continue reading
