What is an Air Operated Diaphragm Pump
A diaphragm pump is a positive displacement pump which operates with a flexible diaphragm, and integrated check valves. The diaphragm is moved inward & outward toward the pump body which works in conjunction with the check valves and draws in and expels the fluid out the pump casing.
The most common diaphragm pump is an Air Operated Double Diaphragm (AODD) pump.
The AODD is a form of positive displacement pump in which has two pump chambers, a “left” & a “right”. The left and right chambers each have their own diaphragm which interconnect with a shaft so when the one moves, the other one moves proportionality at the same time.
Applications for Air Operated Diaphragm Pumps
Diaphragm Pumps have a wide variety of applications and uses in many industries including food, dairy, pharmaceutical and cosmetic industries, where Stainless Steel pumps are used for these hygienic requirements.
Air pumps are very commonly used in the food sector as the transfer of the fluid does not disrupt the chemical properties and consistency of products such as milk, buttermilk, yogurt, cream, mustard, mayonnaise, ketchup and similar products.
Other uses of AODD pumps include transfer of petroleum products, oil and sludge removal operation, transfer of many types of chemicals, including adhesives, solvents, solvent and water based glues and adhesives, paints and inks. The diaphragm pump is the preferred option for these and other types of chemicals and are widely used as they have the ability to operate safely in a flammable environment.
