10 essentials when selecting a double diaphragm pump
Technical Insights to Help You Select the Right Double Diaphragm Pump
Selecting the right diaphragm pump is critical for process reliability, safety, and energy efficiency. Whether you are evaluating an AODD pump (air-operated double diaphragm pump) or an EODD pump (electric double diaphragm pump), proper sizing and material selection directly impact performance and total cost of ownership.
This whitepaper outlines the 10 essential factors engineers and plant managers must consider when selecting a double diaphragm pump, including fluid compatibility, viscosity influence, suction head limitations, pump curve interpretation, ATEX safety, and lifecycle cost comparison.
