Which pump is typically used for low-pressure applications in oil sprays or emulsifiable concentrates?

The pump typically used for low-pressure applications in oil sprays or emulsifiable concentrates is the gear pump. Gear pumps are well-suited for handling viscous fluids, such as oils and emulsions, due to their design that provides a continuous flow at a consistent pressure. They operate by using the meshing of gears to create a vacuum that draws the liquid into the pump and then forces it out, enabling effective handling of thicker fluids without shearing or breaking the emulsion.

In agricultural applications, especially when dealing with pesticides or other chemical formulations that often require mixing with oils or emulsifiable concentrates, gear pumps excel at maintaining the desired flow rate and pressure. They can effectively manage the viscous nature of these products while delivering them at a low, steady rate, which is essential for ensuring a uniform application without damaging the integrity of the chemicals.

Other pump types may not offer the same efficiency for these specific applications. For example, diaphragm pumps are more commonly used for applications that need a highly accurate flow measurement but may not be suited for high-viscosity products as effectively as gear pumps. Roller pumps can serve low-pressure applications, but they are better suited for transferring non-viscous liquids. Centrifugal pumps are generally used for clear liquids and are less
