Which of the following is NOT an advantage of piston pumps?

1. Maneuverability

2. No leakage inside the pump chamber

3. Output is virtually unaffected by pressure

4. High durability

The correct answer is: Maneuverability

Maneuverability is not considered an advantage of piston pumps. While piston pumps are effective in various applications, their design typically makes them less portable compared to other types of pumps. Piston pumps can be bulky and may require more setup time, which affects how easily they can be moved or adjusted on-site. In contrast, the other characteristics highlight the strengths of piston pumps. They are known for effectively minimizing leakage within the pump chamber, which contributes to efficiency and reduces the environmental impact of spills. Additionally, piston pumps maintain output consistency across a range of pressures, making them versatile for different applications. Their construction typically emphasizes high durability, allowing them to withstand varied operational conditions and continue functioning effectively over time. Understanding these aspects helps clarify the limitations of maneuverability in relation to the overall performance benefits of piston pumps.
