What type of pumps discharge fluid on both strokes of the piston?

• A. Single acting
• B. Reciprocating
• C. Double acting
• D. Centrifugal

Answer: (C)

Pumps that discharge fluid on both strokes of the piston are referred to as double acting pumps. This design incorporates two chambers, allowing the pump to push fluid during both the forward and backward motions of the piston. This results in a continuous flow of fluid, making double acting pumps more efficient for certain applications compared to single acting pumps, which only discharge on one stroke. In a double acting pump, each stroke of the piston creates a pressure change in both chambers simultaneously, enabling the fluid to be discharged continuously rather than in a pulsing manner. This can be particularly advantageous in situations where a steady flow is critical. The other types of pumps listed, such as single acting and centrifugal pumps, operate under different principles. Single acting pumps only discharge fluid on one stroke of the piston, while centrifugal pumps utilize rotational motion and are driven by an impeller rather than a piston mechanism. Reciprocating pumps broadly describe both single and double acting configurations but do not specifically indicate the discharge characteristics on both strokes.
