What is a disadvantage associated with diaphragm pumps?

Diaphragm pumps are designed to provide a reliable means of fluid transfer across a variety of applications. However, one notable disadvantage of diaphragm pumps is their relatively high cost. Compared to other types of pumps, they can be more expensive due to their construction and the materials used, which must be durable enough to handle the pumping mediums, including potentially corrosive or hazardous liquids.

This higher cost can be prohibitive for some users, especially in applications where budget constraints are significant. While some pumps may be specifically designed to be cheaper or simpler, diaphragm pumps are often chosen for their efficiency and reliability at the expense of a lower price point.

The incorrect choice suggesting they are relatively inexpensive misunderstands the overall market trend for diaphragm pumps. On the other hand, the considerations regarding size and adaptability to various pressures highlight other aspects of diaphragm pump characteristics but do not reflect the primary disadvantage of cost.
