What is a major disadvantage of piston pumps in aquatic weed applications?

The primary disadvantage of piston pumps in aquatic weed applications is their relative low volumes delivered. Piston pumps are designed to create high pressure, making them effective for applications where precise pressure control is beneficial. However, this high-pressure capability often comes at the cost of the volume of liquid they can move. In aquatic weed control, where larger volumes of herbicides might be needed to effectively treat extensive areas, the low flow rates of piston pumps can limit their usefulness.

While other options highlight potential issues associated with piston pumps, focusing on low volume delivery is key. For instance, the inability to handle abrasive materials is a concern for some pumps, but piston pumps can be designed to handle certain levels of abrasiveness depending on the materials used in their construction. Low adaptability to service types and high operational costs may also be factors in considering different pump types, but they do not specifically address the unique challenges presented in aquatic environments where large treatment areas need to be covered efficiently. This makes low volume delivery a significant drawback in the context of aquatic weed applications.
