Centrifugal Pump Efficiency: BEP, VFD, System Optimization
Most facility managers focus on a pump’s purchase price. But here is a startling fact: for an industrial centrifugal pump running 24/7, the purchase cost represents only 5–10% of its total lifecycle cost. The remaining 85–90% is electricity consumed over its 15–20 year service life. A pump ...Read more -
