Which component is not typically found in a gear pump?

• A. Piston
• B. Gear teeth
• C. Casing
• D. Seal

Answer: (A)

A gear pump specifically uses gears to move fluids and is characterized by its key components: gear teeth that mesh together to create a pumping action, a casing that contains the gears and fluid, and seals that prevent leakage and maintain pressure. The essential operational mechanism of a gear pump relies on the rotation of the gear teeth to draw fluid into the pump and then expel it. The inclusion of a piston is not typical in gear pumps, as they operate through the rotational motion of gears rather than the reciprocating motion seen in piston-based pumps. This distinction is crucial because it clearly differentiates gear pumps from other types of pumps such as reciprocating pumps or piston pumps, where pistons are essential for their function. Understanding the design and operational principles of a gear pump helps in identifying its components and clarifying why the presence of a piston would not align with its intended function.
