During a simple flow test, which two parameters are monitored and compared against expected performance?

• A. Temperature and humidity
• B. Discharge pressure and flow
• C. Valve position and noise
• D. RPM and current

Answer: (B)

The test focuses on the pump’s hydraulic output, checking how much water it can move and the pressure it creates. The two parameters you monitor and compare to the expected performance are the discharge pressure and the flow. By measuring these and comparing them to the pump’s performance curve or test specification, you can verify that the pump is delivering the correct flow at the expected pressure.

Temperature and humidity don’t indicate hydraulic performance, valve position and noise are more about potential symptoms than quantified output, and RPM and current relate to the motor drive rather than the pump’s actual hydraulic capability.
