What is a significant disadvantage of gas-operated double-acting piston pumps?

Gas-operated double-acting piston pumps are often considered more expensive than other types of pumps, such as diaphragm pumps or mechanical pumps. This increased cost can be attributed to their more complex design, the materials used in their construction, and the manufacturing processes required to produce them.

Furthermore, the cost is not merely a reflection of the pump's initial purchase price. Long-term maintenance and operational costs, as well as the potential need for specific parts or refueling (in the case of gas-operated pumps), can add to the overall expense. In many applications, users seeking cost-effectiveness might prefer simpler and less costly pump options, particularly if the performance and reliability can meet their requirements with lower upfront and long-term expenditures.

While there are other factors that may affect the choice of pump, such as the weight and operational training requirements, the significant financial implications of utilizing gas-operated double-acting piston pumps strongly highlight their disadvantage in terms of cost.
