Which pump type is best suited for handling fluids that contain a lot of gas or vapor?

• Gear pump
• Diaphragm pump
• Centrifugal pump
• Peristaltic pump

What does the term "priming" refer to in pump operation?

• The process of setting the pump speed
• The action of removing air or vapor from the pump and suction line
• The process of cleaning the pump before use
• The adjustment of the pump’s discharge pressure

What is the primary reason for using a pump with a magnetic drive (mag-drive)?

• To reduce operational noise
• To eliminate shaft seals and reduce the risk of leaks
• To increase the pump’s flow rate
• To handle higher temperatures

Which type of pump is typically used for high-flow, low-pressure applications, such as in swimming pools?

• Gear pump
• Peristaltic pump
• Centrifugal pump
• Screw pump

What is a "pump curve," and why is it important?

• A graph showing the pump’s efficiency at different speeds; it is used to optimize performance.
• A chart displaying the relationship between flow rate and pump head; it helps in selecting the right pump for an application.
• A diagram of the pump’s internal components; it is used for maintenance purposes.
• A record of the pump’s historical performance; it is used for predictive maintenance.

What is a common application for a peristaltic pump?

• Moving large volumes of water in a municipal system
• Dispensing precise volumes of fluids in medical or laboratory settings
• Transferring bulk solids in a manufacturing plant
• Circulating engine coolant in an automotive engine

What maintenance task is critical for prolonging the life of a centrifugal pump?

• Regularly checking and replacing the pump’s impeller
• Monitoring and adjusting the pump’s flow rate frequently
• Ensuring proper alignment of the pump and motor shaft
• Cleaning the pump casing and removing any debris

Which of the following is a key disadvantage of diaphragm pumps?

• High maintenance requirements
• Limited flow capacity
• High energy consumption
• Inability to handle corrosive fluids
