Air operated double diaphragm pumps harness the power of pressure differentials in their air chambers, ingeniously alternating between suction and positive fluid pressure in the fluid chambers. Equipped with reliable ball checks, they ensure a steady, positive flow of fluid with unwavering dependability. As air pressure is introduced, pump cycling initiates, effortlessly responding to the demands placed upon it. This remarkable pump maintains line pressure with precision, halting cycling once the maximum line pressure is achieved (when the dispensing device is closed). It seamlessly resumes pumping as required, delivering consistent performance.
What are air operated diaphragm pumps used for?
Recognized as versatile and indispensable workhorses, AODD pumps find their utility in a wide array of applications, including:
- Mining - Expertly dewatering both above and below ground sites, as well as quarries. They excel in transferring slurries and sludge, and effectively manage the transfer of fuel for vehicles and heavy construction equipment.
- Coatings - Efficiently transferring, dispensing, and dosing paint or ink. They serve as reliable feed pumps for spray guns.
- Ceramics - Facilitate the movement of ceramic slips, handle day tank transfers, and efficiently fill molds with precision.
- Chemical Processing - Ideal for loading and unloading tankers, acting as a portable utility pump, and adept at batching or dosing chemicals.
- Electroplating and Anodizing - Skilled in replenishing chemicals in plating or metal finishing tanks, enhancing agitation of cleaning solutions, and optimizing filtration processes.
- Pulp and Paper - Proficient in transferring printing inks, glues, and bulk adhesive, ensuring seamless and efficient operations.
- Oil and Gas - Essential for filter press operations, bulk fuel transfer, and managing transfers within settling ponds with ease.
- Water and Wastewater Treatment - Excel in transferring suspended solid media, operating filter presses, and serving as a reliable utility pump.





Service kits are meticulously designed to accommodate two separate diaphragm pump functions: 1. AIR SECTION, 2. FLUID SECTION. The FLUID SECTION is thoughtfully subdivided to align with typical part MATERIAL OPTIONS.
