Pumps that are driven by air pressure are also known as what?

Pumps that are driven by air pressure are referred to as pneumatic pumps. These pumps operate using compressed air to create a pressure differential, which moves fluids or slurries. Pneumatic pumps are widely used in various applications because they are capable of handling a range of materials and can operate efficiently in environments where electricity may not be readily available or safe to use.

Pneumatic systems leverage the energy in compressed air, allowing for effective pumping without being reliant on electrical components. This characteristic makes them particularly valuable in industrial settings, where explosive or hazardous environments exist. Additionally, pneumatic pumps can be designed for different flow rates and pressures, allowing for versatility in their applications.

In contrast, hydraulic pumps utilize liquid fluid power rather than air pressure, vacuum pumps create a space devoid of air, and power pumps might refer to various pumps that can be driven by different energy sources, but they do not specifically indicate an air pressure-driven mechanism. Therefore, pneumatic pumps are the correct classification for pumps activated by air pressure.
