What are Electric Diaphragm Pumps?
What’s the biggest difference between electric and air operated diaphragm pumps? Their power source. Electric diaphragm pumps use electricity, while air operated diaphragm pumps (AOD pumps) get power from compressed air. Switching to an electric diaphragm pump, users can save up to 80% on operating costs and energy savings. Electric diaphragm pumps, also known as sealless process pumps for specific designs, are used to transfer fluids efficiently and reliably.
Depending on the technology, electric diaphragm pumps can transfer liquids with low, medium or high viscosities, as well as liquids with suspended solids. They can handle many aggressive chemicals such as acids because of the wide variety of body construction materials (polypropylene, stainless steel, aluminum, etc.) and diaphragms (santoprene, PTFE, etc.)
Electric diaphragm pump can have either two- or three-diaphragm chamber options. ARO offers both technologies, with the EVO Series™ 200 (electric double diaphragm pumps) and the EVO Series™ 300 (electric triple diaphragm process pumps). ARO’s EVO Series™ 300 is the industry leading electric process diaphragm pump and 2023 Pump Industry Awards’ Product of the Year.
