Which of the following statements is correct regarding the start-up operation of a non-condensing turbine-driven feed pump?

Correct Answer: Option D — Open the pump suction valve prior to admitting steam to the turbine.

Centrifugal feed pumps must have their suction valves fully open and casings properly vented and warmed up prior to turbine startup. Admitting steam to a dry or unprimed pump causes catastrophic impeller and wear-ring damage.
