What is a key disadvantage of piston pumps?

A key disadvantage of piston pumps is their cost relative to diaphragm pumps. Piston pumps typically have more complex designs and higher manufacturing costs, which can make them more expensive to purchase and maintain. This cost factor can limit their use, especially in applications where budget constraints are significant or where simpler alternatives, like diaphragm pumps, can effectively meet the needs of the task at hand.

While piston pumps can deliver high pressure and operate effectively in certain situations, their complexity and initial investment requirements can deter users from selecting them. Other alternatives like diaphragm pumps may provide similar benefits at a lower cost, making them more attractive for many applications. The economic aspect is particularly vital, especially in environments where budget constraints are important to operations.
