What is a pneumatic pump typically used to transport?

A pneumatic pump is specifically designed to transport air and gases using the principle of compressed air. It operates by utilizing air pressure to create a vacuum or push air through a piping system, making it ideal for transferring gas-based substances. This technology is commonly used in various applications, including the conveyance of powdered materials, vapor, and other gaseous compounds in industrial settings.

While other pump types may handle liquids, pneumatic pumps excel in controlling and moving gaseous substances efficiently. This operational characteristic distinguishes pneumatic pumps from those meant for liquids, which would handle duties such as transporting municipal sewage or sludge, making the other options less applicable to the function of a pneumatic pump.
