What type of pump utilizes two meshed gears?

The correct answer is the rotary gear pump, which operates using two meshed gears to move fluid. In this type of pump, the gears rotate in opposite directions, creating a vacuum that draws the fluid into the pump and traps it between the gear teeth. As the gears continue to rotate, the fluid is displaced and pushed out of the discharge port. This mechanism allows for a continuous flow of liquid and is particularly effective for handling viscous fluids.

This design enables rotary gear pumps to maintain a steady output flow and also allows for precise handling of varying flow rates and pressures, making them versatile for many applications in industrial and mobile water supply settings. The design of the two meshed gears is fundamental to the pumping action, distinguishing it from other pump types.

Other pumps, like piston pumps and centrifugal pumps, rely on different operating principles, such as diaphragms or rotating impellers, which do not involve meshed gears for fluid movement.
