Global Pumps offers and stocks a complete range of air-operated diaphragm pumps in different materials for pumping and transferring liquids and chemicals.
The air-operated double-diaphragm pump - or AODD pump - is driven by compressed air, rather than electricity, and is the most commonly used portable pump, particularly in mining and chemical applications.
The working principle revolves around a combination of reciprocating actions by different components, such as the diaphragm, valve seats and valve balls working together to pump the liquid.
This design gives AODD pumps a number of unique advantages, such as self-priming capabilities, up to 7m suction lift and the ability to run dry without damage. They are also capable of handling highly viscous, highly volatile and dangerous liquids.
Global Pumps offers the Verderair brand of air-operated diaphragm pumps in port sizes from 0.25 to 3in, delivering maximum flow rates from 19 to 2000L/min.
Global Pumps has published “The ultimate air operated diaphragm pump cheat sheet” that explains the technology in full and can be downloaded from the company’s website.
