Which pump is commonly described as a horizontal pump?

• A. End Suction Pump
• B. Gear Pump
• C. Fire Pump
• D. Horizontal Pump

Answer: (D)

The idea being tested is how pump orientation is described. A pump with its shaft running parallel to the ground is described as a horizontal pump. In fire pump practice, most standard, installable pumps are horizontal (like horizontal end-suction or horizontal split-case types), so “horizontal pump” is the common descriptor for this arrangement. The other terms refer to where the suction is located (end suction), the internal mechanism (gear), or the service purpose (fire pump) but don’t indicate the pump’s orientation. Therefore, the label that describes the physical alignment most directly is the horizontal pump.
