Pump Operator Exam: Trivia Quiz!
(216).jpg "Pump Operator Exam: Trivia Quiz! - Quiz")
A pump operator is supposed to work with compact or heavy pumps for transferring liquid. They generally work as chemical operators, pump station operators, purification operators, and tank car loaders. A pump operator performs the complete inspection and operations. This quiz has been developed to test your knowledge of fire apparatus pump operations. Let's try it out!

Types of methods of power transfer are:
- A.
Split shaft
- B.
Split shaft
- C.
Power take off
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The correct answer is "All of the above" because the question asks for the types of methods of power transfer, and all three options listed (split shaft, split shaft, and power take off) are valid methods of power transfer. Therefore, the answer is that all of these methods are types of power transfer.Rate this question:

Midship means
- A.
The middle of the pump shaft
- B.
Pump mounted behind the cab, midway between front and rear axles
- C.
Water comes out of the middle of the truck
- D.
All of the above
Correct Answer
B. Pump mounted behind the cab, midway between front and rear axlesExplanation
The correct answer is "Pump mounted behind the cab, midway between front and rear axles." This means that the pump is located in the middle of the fire truck, behind the cab and between the front and rear axles. This positioning allows for optimal weight distribution and stability when operating the pump.Rate this question:

Direct drive means
- A.
Pump driven directly from engine crankshaft pulley
- B.
You have to be driving the engine to pump water
- C.
Pump is installed on the front of the engine only
- D.
Both b & c
Correct Answer
A. Pump driven directly from engine crankshaft pulleyExplanation
Direct drive means that the pump is driven directly from the engine's crankshaft pulley. This means that there is a direct mechanical connection between the engine and the pump, allowing the engine's power to be transferred directly to the pump without any additional components or systems. This type of drive system is commonly used in applications where a high level of power and efficiency is required, such as in industrial machinery or high-performance vehicles.Rate this question:

The intake relief valve dumps water from the inlet side of the pump to:
- A.
Atmosphere
- B.
Booster tank
- C.
Both a & b
- D.
Any open line
Correct Answer
C. Both a & bExplanation
The intake relief valve dumps water from the inlet side of the pump to both the atmosphere and the booster tank. This means that the valve releases excess water into the atmosphere to relieve pressure, and it also diverts water to the booster tank for storage or further use.Rate this question:

Water enters the intake/suction side of the pump supplied by:
- A.
Gravity pressure from tank
- B.
Distribution system under pressure
- C.
Drafting from a static water source
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The correct answer is "All of the above" because water can enter the intake/suction side of the pump through various means. It can be supplied by gravity pressure from a tank, through the distribution system under pressure, or by drafting from a static water source. All of these methods can be used to supply water to the pump, depending on the specific situation and setup.Rate this question:

To get water from a static source:
- A.
Use hard suction and strainer
- B.
Pump must be primed
- C.
Turn stem on hydrant until water flows to the engine
- D.
Both a & b
Correct Answer
D. Both a & bExplanation
The correct answer is "Both a & b". To get water from a static source, both hard suction and a strainer must be used. Hard suction is a type of hose specifically designed for drafting water from a static source. Additionally, the pump must be primed before it can effectively draw water. Priming involves removing air from the pump and filling it with water to create a vacuum. Therefore, both using hard suction and a strainer, as well as priming the pump, are necessary to successfully get water from a static source.Rate this question:

A possible cause for the pump operator not to get a reading on the pressure gauge when the pump is put in service is:
- A.
pump drive system is open
- B.
pump drive system not fully engaged
- C.
Water source is not big enough
- D.
Need a larger diameter hose
Correct Answer
B. pump drive system not fully engagedExplanation
If the pump drive system is not fully engaged, it means that the pump is not properly connected to the power source or the power transmission system. This can result in the pump not functioning properly and not generating enough pressure to register on the pressure gauge.Rate this question:

If the pump will not develop sufficient pressure the probable cause is:
- A.
Transmission isn’t in proper gear
- B.
Relief valve activating to soon
- C.
Both a & b
- D.
The engine is the wrong size for the pump
Correct Answer
C. Both a & bExplanation
If the pump is not able to develop sufficient pressure, the probable cause could be both the transmission not being in the proper gear and the relief valve activating too soon. Both of these factors can contribute to the pump not being able to generate enough pressure. However, the engine being the wrong size for the pump is not mentioned as a probable cause in this context.Rate this question:

Cavitation is defined as:
- A.
Condition in which vacuum pockets form in pump and cause vibrations, loss of efficiency, and possible damage
- B.
Condition in which to much water enters the pump
- C.
Condition in which a valve is closed to quickly
- D.
All of the above
Correct Answer
A. Condition in which vacuum pockets form in pump and cause vibrations, loss of efficiency, and possible damageExplanation
Cavitation is a condition in which vacuum pockets form in a pump, resulting in vibrations, loss of efficiency, and potential damage. This occurs when the pressure of the liquid being pumped drops below its vapor pressure, causing the formation of vapor bubbles. These bubbles collapse when they reach a region of higher pressure, leading to the formation of shock waves that can cause the aforementioned issues. Therefore, the correct answer is that cavitation is the condition in which vacuum pockets form in a pump and cause vibrations, loss of efficiency, and possible damage.Rate this question:

Cavitation can happen in any pump when:
- A.
A valve is closed to quickly
- B.
Pump speed is set to low
- C.
Discharge flow starts to exceed intake flow
- D.
All of the above
Correct Answer
C. Discharge flow starts to exceed intake flowExplanation
When the discharge flow starts to exceed the intake flow in a pump, it can lead to cavitation. Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing the formation of vapor bubbles. These bubbles collapse when they enter a higher pressure region, causing shock waves and damage to the pump. Therefore, when the discharge flow exceeds the intake flow, it creates a pressure drop in the pump, leading to cavitation.Rate this question:
