FLORIDA PUMP OPS TEST UPDATED ACTUAL
EXAM QUESTIONS AND CORRECT ANSWERS
Florida Pump Operator Practice Exam
Section 1 – Pump Construction & Theory
Questions 1–10
1. Which type of fire pump is used on nearly all modern fire apparatus?
A. Rotary gear pump
B. Reciprocating pump
C. Centrifugal pump
D. Diaphragm pump
Correct Answer: C
Explanation: Modern fire engines almost universally use centrifugal
pumps because they provide smooth, continuous flow, are efficient at high
volumes, and require relatively little maintenance.
2. Cavitation occurs when:
A. Pump pressure exceeds relief valve settings.
B. Water boils inside the pump due to low intake pressure.
C. Air enters the discharge hose.
D. The engine overheats.
Correct Answer: B
,Explanation: Cavitation occurs when intake pressure drops low enough
that water vaporizes inside the pump. The collapsing vapor bubbles can
damage pump components.
3. A pressure relief valve primarily protects against:
A. Engine overheating
B. Excessive discharge pressure
C. Water hammer
D. Pump overheating
Correct Answer: B
Explanation: A pressure relief valve automatically limits excessive
discharge pressure caused by changing flow demands.
4. Which statement best describes a centrifugal pump?
A. It traps water between gears.
B. It uses pistons.
C. It uses an impeller to impart velocity to water.
D. It compresses air to move water.
Correct Answer: C
Explanation: A centrifugal pump uses a rotating impeller to increase water
velocity, which is then converted into pressure.
5. Net Pump Pressure (NPP) is the difference between:
A. Engine RPM and discharge pressure
, B. Intake pressure and discharge pressure
C. Tank pressure and hydrant pressure
D. Friction loss and nozzle pressure
Correct Answer: B
Explanation: NPP equals discharge pressure minus intake pressure and
represents the pressure developed by the pump.
6. The eye of the impeller is where:
A. Water exits the pump.
B. Water enters the impeller.
C. Pressure is highest.
D. Foam concentrate is injected.
Correct Answer: B
Explanation: Water enters through the eye of the impeller before being
accelerated outward by centrifugal force.
7. The primary purpose of a primer is to:
A. Increase discharge pressure.
B. Remove air from the pump during drafting.
C. Lubricate the impeller.
D. Increase engine speed.
Correct Answer: B
Explanation: Primers evacuate air from the pump and suction hose,
allowing atmospheric pressure to force water into the pump.
