What is the main purpose of using a roller pump?

The main purpose of using a roller pump is to facilitate herbicide applications. Roller pumps are designed to handle a variety of agricultural liquids, particularly those involved in applying herbicides. They operate by using rollers to create suction and move the liquid through the pump, which allows for consistent and controlled delivery of the herbicide to the target area.

This type of pump is especially suited for herbicides because it can manage the viscosity and abrasiveness of the solutions used without damage to the pump. Its design allows for the incorporation of herbicides into spray applications efficiently and effectively, making it a preferred choice in weed management practices.

In contrast, other options may involve different types of pumps better suited for specific applications. For example, high-pressure pumps are typically used for systemic insecticides, while liquid transport of fertilizers requires pumps designed for those specific materials. Additionally, the spraying of abrasive chemicals might require specialized pumps that can withstand wear and tear, which are not the primary function of roller pumps.
