Pressure gauges connected to both suction and discharge sides of a pump should be connected?

Pressure gauges connected to both the suction and discharge sides of a pump should be connected to the pressure taps supplied on the pump. This is important because these pressure taps are specifically designed to provide accurate measurements of the pressures at these points in the system. They are strategically placed by the manufacturer to ensure optimal functionality and reliability when monitoring pump performance.

By using the designated pressure taps, operators can effectively assess the pump's performance, including determining flow rates and understanding the total dynamic head. It also allows for easier troubleshooting and maintenance, as any discrepancies in pressure readings can be appropriately investigated. The precise location of the taps helps eliminate potential inaccuracies that might arise if gauges were attached at other locations, such as a flow meter or main pipeline, which may influence the pressure readings due to additional factors like friction losses or turbulence.
