Which term describes the total pressure available at the pump discharge flange?

• A. Suction Pressure
• B. Discharge Pressure
• C. Rated Pressure
• D. Net Pressure

Answer: (B)

Discharge pressure is the pressure on the discharge side of the pump, at the discharge flange. It represents the total pressure the pump can push into the system through the discharge piping, including the pressure the pump adds and the system conditions right at that point. Suction pressure is measured on the inlet side, not where the water is being discharged. Rated pressure is simply the pump’s design pressure specification, not the actual pressure at the discharge flange. Net pressure isn’t the standard term used for the pressure at the discharge flange. So the term that best describes the total pressure available at the pump discharge flange is discharge pressure.
