What is a beneficial characteristic of diaphragm pumps compared to piston pumps?

Diaphragm pumps are known for their ability to handle a variety of fluids while maintaining a level of separation between the fluid and the mechanical components. This characteristic allows them to efficiently pump even abrasive or corrosive materials without risking damage to the pump itself. Compared to piston pumps, diaphragm pumps tend to be less expensive, particularly in applications where fluid compatibility and leakage prevention are critical.

The diaphragm design also means there are fewer moving parts exposed to the pumped fluid, which can reduce wear and tear, contributing to a lower overall cost. This advantageous feature leads to greater durability and potentially lower operational costs. While diaphragm pumps may not necessarily deliver higher volumes or handle higher pressures as effectively as piston pumps in all contexts, their cost-effectiveness and maintenance simplicity in many situations often make them a preferred choice for specific applications.
