When a mechanical seal fails, it’s rarely sudden. In most cases, the pump has been giving warnings for days, weeks, or even months. Small changes—slight drips, minor heat increases, subtle vibrations—can escalate into leaks, bearing damage, and full system shutdowns if left unaddressed.

Understanding Pump Curves: The Key to Efficient Performance Choosing the right pump isn’t just about size or horsepower—it’s about performance. And the secret to understanding performance lies in the pump curve. A pump curve is your roadmap to efficiency, showing how a pump will behave under different flow and pressure conditions. What a Pump Curve Shows A standard pump curve plots flow (GPM) against head (pressure). The sweet spot, called the Best Efficiency Point (BEP) , is
