Best efficiency point (BEP) is one of the key indicators of pump performance. BEP is the flow rate at which the pump operates most efficiently. Generally speaking, most pumps will deviate from the flow point to some extent. However, you need to make sure that your pump only works to a small extent.

When monitoring pump performance and efficiency, monitoring the pump's distance from the flow point is one of the best places to start. By monitoring BEP, you can make adjustments and ensure your pump is operating at the most efficient flow, maximizing performance and reducing maintenance and repair costs.

If you are running too far from the BEP, you will not be able to use the pump as efficiently as possible. Running a pump too far from the BEP for extended periods of time can also cause excessive wear on the system, leading to pump failure.

Operating the pump too far to the right of the BEP increases the risk of cavitation, which occurs when air bubbles in a liquid burst under force.

Cavitation can damage the pump casing and, over time, may lead to pump failure because operating the pump away from the BEP causes an imbalance of forces within the system, which wears the system down.

Consider the flow rate of the fluid in the system. If the flow rate is low and bubbles form and collapse violently, the casing inside the pump will obviously be impacted. If your pump continues to experience this beating over the course of a year, you can see how cavitation can cause excessive wear on the system, leading to increased maintenance and repair costs. excessive vibration

Vibration is another effect of running the pump too far from the BEP, causing the shaft area to buckle, resulting in poor pump performance. Hydraulic imbalance caused by running too far from the BEP can cause problems within the impeller as the liquid evaporates.

Excessive vibration causes the fluid to implode with great force, which then sends a sock wave throughout the system. Over time, continued operation in this manner can lead to impeller damage, system corrosion, and ultimately, possible pump failure. flow recirculation

When you operate the pump near the BEP, the fluid inside will flow in a more even manner. The further away from the BEP, the stress becomes distorted and your system suffers. When operating too far from the BEP, pressure gradients may cause local flow reversals, a phenomenon known as flow recirculation.

Recirculation can occur at the impeller suction, discharge, or both. The phenomenon of recirculation can cause severe instability and reduce flow, which not only stresses the system but can also lead to pump failure if parts of the impeller break. When parts of the impeller break, repair costs can be high.
