PUMP OPERATOR FINAL TEST 2026 QUESTIONS WITH
CORRECT ANSWERS GRADED A+
● Rated Capacity. Answer: Maximum flow a pump is certified to deliver at a specified
pressure
● Draft Operations. Answer: Pumping water from a static source such as a pond or cistern
using suction
● Lift. Answer: Vertical distance water must be raised from a static source to the pump
● Cavitation. Answer: Damage caused when pump inlet pressure drops too low creating
vapor bubbles
● Pressure Governor. Answer: Device maintaining constant pump discharge pressure
regardless of flow changes
● Relief Valve. Answer: Safety device preventing excessive pressure buildup in the pump
discharge
● Priming. Answer: Process of removing air from the pump and intake to allow drafting
operations
● Primer Pump. Answer: Auxiliary pump used to create vacuum and draw water into the
main pump
● Intake Pressure. Answer: Pressure of water entering the pump from the supply source
● Discharge Pressure. Answer: Pressure of water leaving the pump through the discharge
outlets
● Net Pump Pressure. Answer: Discharge pressure minus intake pressure representing
work done by the pump
● Engine Pressure. Answer: Pressure at the pump discharge commonly used to calculate
nozzle pressure
● Nozzle Pressure. Answer: Required operating pressure at the nozzle tip for effective fire
attack
