What application method involves transferring fluids from one tank to another?

Centrifugal pumping is the application method that involves transferring fluids from one tank to another. This method uses a pump to create movement through centrifugal force, which is generated by a rotating impeller inside the pump. As the impeller spins, it draws fluid into the pump and pushes it out through the discharge pipe, effectively transferring it between tanks or to the application site.

This method is commonly used in situations where large volumes of liquids need to be moved efficiently, making it ideal for various applications in aquatic pest management where precise control of liquid transfers is necessary to ensure appropriate treatment concentrations and coverage. In contrast, the other methods listed—like handgun spraying, subsurface injections, and bottom placement—are focused on the direct application of liquids in targeted areas rather than on transferring fluids between storage locations.
