Air Operated diaphragm pumps
Air operated diaphragm pumps offer a reliable operation with the ability to pump a wide variety of products, operating on liquids with a viscosity similar to water up to a thick, highly viscose liquid at around 30,000 cPs.
They are extensively used within the Chemical, pharmaceutical, ink, paint, food & beverage industries, to name a few, and come in various body materials are available in cast iron, aluminum, stainless steel, Acetal, Polyethylene, polypropylene & solid PTFE.
How do Diaphragm pumps work?
Diaphragm pumps work with two flexible diaphragms that move back and forth, this movement creates a temporary chamber for fluid to be drawn and expelled on each stroke.
AODD Pump Certifications
We offer a number of pump certifications for diaphragm pumps, these certifications are Atex, FDA, 3A, and EHEDG rated. An Atex rating can be offered within certain pump ranges and will be suitable for use within a potentially explosive environment.
FDA approved pumps are a sanitary version for environments such as food production and the cosmetic industry. 3A rated pumps offer a higher sanitation level (than FDA Approved pumps), and are suitable for use within the pharmaceutical and the dairy industry.
EODD – Electric Operated diaphragm pumps
Electric Diaphragm pumps are becoming more and more common and are a great option if you are looking at saving energy (compared to using an air compressor) and don’t have the option of using compressed air.
We also offer a range of 12/24 volt diaphragm pumps that are great at transferring small amounts of water.
Find the right diaphragm pump for your application
In order to match the correct pump, you must ascertain a few bits of information.
- Know the required Flow Rate in order to match the correct pump size.
- Know what you are pumping so you/we can select the correct materials
- Have any certification requirements? (Sanitary / Atex Requirements)
- Do you have access to compressed air? If not, you may need to look at an EODD option.
