Which component flow path is created by the pump casing for suction and discharge?

• A. Suction and discharge connections
• B. Intake manifold
• C. Outlet valve
• D. Expansion chamber

Answer: (A)

The pump casing creates the two flow paths—the suction side and the discharge side—through its connected ports. Fluid is drawn in via the suction connection, moves into the impeller where it is pressurized, and exits through the discharge connection into the piping network. The casing often includes a volute or similar shaping that guides the flow from the impeller into the discharge path, helping convert some of the velocity into pressure. The intake manifold is a separate assembly that collects fluid from multiple suction lines and feeds a single pump, not the direct path created by the pump casing. The outlet valve sits downstream in the discharge line, and the expansion chamber serves to dampen pressure surges rather than form the main flow path.
