What type of pumps are often used in smaller vehicle-mounted sprayers?

Roller-type pumps are particularly suited for smaller vehicle-mounted sprayers due to their efficiency and ability to handle a variety of liquid viscosities. These pumps utilize a mechanism where rollers rotate around a set of fixed vanes, creating a continuous flow of liquid, which is ideal for delivering pesticides consistently at lower flow rates.

Additionally, roller-type pumps are known for their durability and reliability, making them well-suited for the demands of agricultural applications. They can easily manage the pressures commonly associated with sprayer systems, and their design allows for straightforward maintenance, enhancing their longevity and performance in the field.

In contrast, diaphragm pumps, while useful for certain applications, may not provide the same level of flow consistency and pressure regulation necessary for vehicle-mounted sprayers at smaller scales. Gear pumps, generally preferred for high flow and high pressure scenarios, can be less effective with certain pesticide formulations, especially those containing solids or abrasive materials. Centrifugal pumps, on the other hand, are typically more effective for larger applications where high volumes are needed, but may struggle with the precision required for small-scale pesticide applications.
