How is the operational state of a centrifugal pump verified?

Verifying the operational state of a centrifugal pump primarily involves checking flow switches and pressure readings. This method is essential because it provides direct insights into the pump's performance and operating conditions. Flow switches indicate whether the fluid is moving through the system as intended, while pressure readings help determine if the pump is generating the correct pressure for the application. When both measurements are within their expected ranges, it confirms that the pump is operating effectively and efficiently.

Other methods, such as measuring intake temperature, observing mounting positions, or calibrating pump speeds, contribute to overall maintenance or installation checks but do not directly reflect the pump's operational performance in real-time. For instance, temperature measurement may indicate thermal conditions but doesn't reveal flow or pressure status. Similarly, although mounting positions are important for installation, they are less relevant to the actual operational state of the pump. Calibration of pump speed is usually focused on optimizing performance rather than confirming that the pump is currently functioning correctly.
