Why are roller pumps generally not preferred for aquatic weed control?

Roller pumps are generally not preferred for aquatic weed control primarily due to their low pressure capacity for extended spraying. Aquatic weed control often requires the ability to maintain consistent pressure over the length of the application to effectively distribute herbicides across varying water surfaces and vegetation densities. Roller pumps typically have limitations in maintaining high pressure, which is crucial for ensuring that the pesticides are adequately atomized and can penetrate the target plants effectively.

In contrast, other types of pumps, such as diaphragm or centrifugal pumps, are often designed to handle higher pressures and provide more adaptability in terms of pressure regulation, making them more suitable for the varying demands of aquatic applications. This ensures that the product can be uniformly distributed, maximizing effectiveness while minimizing environmental impact.
