We are seeking guidance on conducting an investigation to address the issue of high amperage with our recently installed centrifugal pumps. Currently, some pumps are running in parallel to prevent tripping from motor overload. Any suggestions on resolving this issue would be greatly appreciated. Thank you.
Can the attached item rotate freely? What type of product is it? We require additional details to proceed. Was the engineer responsible for this?
The pumps are operating smoothly, rotating freely to handle hydrocarbon products. The motor size has been verified by the pump vendor to prevent undersizing issues. Product specific gravity has been confirmed to align with the pump design, ensuring optimal performance. However, a concern arises as the motors are drawing high amperage, indicating an overload situation. Identifying the root cause of this issue is crucial. What other factors should be examined to troubleshoot and resolve this problem effectively?
Have you verified the motor overload trip setting? This step is essential to ensure that your motor is operating efficiently and safely. Remember to always check and adjust the overload settings as needed to prevent any potential damage or malfunctions. Keeping this in check will help extend the lifespan of your motor and improve its overall performance.
If the pump is correctly sized and the rotation, voltage, and load are in alignment, the electric motor will perform its job efficiently. It is essential to ensure that the panel is set up correctly with appropriate overloads to prevent overloading issues. Even a small 1/4" difference in impeller size can lead to overloading, so it is crucial to adjust the output and monitor the amps. As an experienced electric motor shop owner, it appears that the load may be too high. It is important to investigate the root cause of the overload.

It appears like the pumps might be either incorrectly sized or possibly dealing with a blockage issue. My first piece of advice would be to check the pump curve against the system curve, ensuring it’s operating near its Best Efficiency Point (BEP). Secondly, confirm there's no blockage in the system causing unnecessary resistance. Also, pay attention to your voltage level; an improper voltage can contribute to high amperage. Make sure to involve an experienced electrical engineer in your investigation.

Answer: 1. Q: What could be causing high amperage in recently installed centrifugal pumps? High amperage in centrifugal pumps could be caused by various factors such as improper pump installation, motor overload, issues with the pump system, or problems with the power supply.
Answer: To troubleshoot high amperage in pumps running in parallel, you can start by checking for any obstructions in the pump system, verifying proper pump installation, examining the power supply for irregularities, and ensuring that the pumps are operating within their design specifications.
Answer: Running pumps in parallel to prevent tripping from motor overload can lead to inefficiencies, increased energy consumption, and potential damage to the pumps due to prolonged operation under high amperage conditions.
Answer: Best practices for resolving high amperage in centrifugal pumps include conducting a thorough inspection of the pump system, ensuring proper installation and alignment, checking for any mechanical issues, and consulting with a professional if needed.
