Beyond the basics such as flow rate, temperature, voltage and media compatibility, there are a host of other critical issues necessary to determine the best pump for your system design. The fundamental design criteria for selecting an electrically operated diaphragm pump to handle air or gases has been well-covered around essential issues such as flow rates, inlet and outlet loads, chemical compatibility, voltage, and ambient and media temperature. But other equally important parameters are often overlooked. Here's a rundown of the most important.
