What type of pump features a water inlet at one end and a discharge opening at a right angle?

• A. Single-suction pump
• B. Double-suction pump
• C. Submersible pump
• D. Centrifugal pump

Answer: (A)

The type of pump characterized by a water inlet at one end and a discharge opening at a right angle is known as a single-suction pump. This design allows for the intake of water from one side, while directing it out at a right angle, which can facilitate easier installation in certain configurations and streamline the flow of water through the system.

In single-suction pumps, fluid enters through one side and moves through the impeller before being discharged. This is particularly useful in applications where space may be limited and a straightforward inlet and outlet path can enhance efficiency. Notably, the configuration aids in reducing turbulence as the water flows through, which can lead to better performance and longevity of the pump.

Other types of pumps, such as double-suction pumps, have two inlets and are designed to balance hydraulic forces, leading to lower shaft stress and are typically used for larger flow applications. Submersible pumps are designed to be submerged in the fluid they are pumping and have a different mechanism of operation. Centrifugal pumps, while they may match a variety of configurations including having discharge openings at various angles, are more general in design and not specifically defined by a water inlet at one end with a discharge at a right angle.
