What is a feature of piston pumps?

Piston pumps are known for their ability to generate high pressure, making them suitable for applications where strong pumping force is necessary. This capability stems from the pump's design, which utilizes a piston to create pressure by moving fluid through a cylinder. As the piston moves, it compresses the fluid, allowing it to be discharged at a significantly higher pressure than what many other pump types can achieve. This feature is particularly advantageous in scenarios where precise application and forceful delivery of fluids are critical, such as in agricultural spraying or when dealing with aquatic pest control methods.

In contrast, while other options may imply characteristics about piston pumps, they do not align with their well-established functions. For instance, piston pumps can often operate effectively across a range of flow rates, allowing for both low and high flow applications, which does not support the notion of inherently low flow rates. Reliability is generally high in piston pumps when properly maintained, contradicting the assertion of reduced reliability. Lastly, the suitability of piston pumps for aquatic use is enhanced by their performance characteristics, as they can handle varied fluid types and conditions commonly found in aquatic environments.
