What is a feature of the watertight areas in a Rotary Gear pump?

The feature of watertight areas in a Rotary Gear pump being formed between the teeth of meshed gears is rooted in the fundamental design and operation of the pump. In a Rotary Gear pump, the meshing of the gears creates distinct chambers that trap the fluid. As the gears rotate, these chambers decrease in volume as they move toward the discharge side, which effectively helps in transferring the fluid through the system. This design is crucial for maintaining consistency in flow and preventing backflow, especially in applications where a certain pressure must be kept.

The creation of these watertight areas between the gear teeth ensures that the fluid remains contained during its movement throughout the pump, thus enhancing the pump's efficiency and effectiveness. It also indicates that the precision in how the gears mesh is vital for the pump to operate correctly, as any misalignment could lead to inefficiencies or leaks.
