Brine pumps are typically classified as positive displacement pumps. This type of pump operates by trapping a fixed amount of liquid and forcing it into the discharge pipe, which allows for precise control over the flow rate and pressure. Positive displacement pumps are well-suited for handling viscous fluids, such as brine solutions, because they provide consistent flow and can manage the dense nature of these liquids effectively.

Dynamic pumps, like centrifugal pumps, rely on rotational energy to move fluid, which may not provide the same level of control when dealing with variations in viscosity that can occur in brine systems. While centrifugal pumps can be effective in many applications, they are generally not as effective as positive displacement pumps for high-viscosity or high-pressure scenarios typical in brine applications. Gear pumps are a subtype of positive displacement pumps, specifically designed for low-to-moderate flow rates and can also be used in certain brine applications, but they are just one type among the broader category of positive displacement pumps.
