In what situations would pneumatic ejectors be used?

• A. For pumping high flows of liquids
• B. For pumping low flows that contain large solids
• C. For pumping low viscosity fluids
• D. For transmitting gas at high pressure

Answer: (B)

Pneumatic ejectors are specifically designed to handle situations where low flow rates of liquids, especially those containing large solids, are involved. They utilize compressed air to create a vacuum or pressure differential that allows for the movement of these liquids, effectively lifting and displacing them even when they contain larger particulates. This capability makes pneumatic ejectors particularly suitable in applications such as sewage or waste handling, where materials can be viscous or contain debris that would obstruct other types of pumping systems. In contrast, pumping high flows of liquids typically requires more traditional systems that can manage the hydraulic conditions efficiently, such as centrifugal or positive displacement pumps. When it comes to pumping low viscosity fluids, these can often be handled effectively with different pump technologies that enable smooth flow without the need for the special mechanisms that pneumatic ejectors use. Lastly, while pneumatic ejectors can work with gases, their primary function revolves around liquid handling, particularly in situations where the liquids may introduce solid contaminants.
