What type of pump operates at low pressure and low volume?

The diaphragm pump is specifically designed to operate at low pressure and low volume, making it suitable for applications where precise flow control is necessary. These pumps use a flexible diaphragm that moves back and forth to create a vacuum that draws fluid into the chamber, and then expels it when the diaphragm moves in the opposite direction. This action allows for effective handling of various fluids, including those that are viscous or contain solids, without the risk of contamination.

The capability of diaphragm pumps to generate pressure and control flow effectively at lower levels is often leveraged in situations like chemical processing, water treatment, or transferring sensitive materials. Their ability to handle a wide range of viscosities and maintain a consistent flow rate at low pressures differentiates them from other pump types that may operate more efficiently at higher pressures and larger volumes.

While centrifugal pumps, gear pumps, and reciprocating pumps generally cater to different operating conditions, they are typically associated with higher pressure applications or varying flow requirements, which doesn't align with the specific characteristics of diaphragm pumps.
