About Diaphragm Pumps

Diaphragm Pumps are a type of positive displacement pump that uses a flexible diaphragm to move liquids and other materials from one place to another. They are commonly used in industrial, commercial, and residential applications for moving fluids, gases, or slurries.

Types of Diaphragm Pumps

There are several types of Diaphragm Pumps that vary in size and application. These include air operated diaphragm pumps (AOD pumps), double diaphragm pumps, membrane pumps, and pneumatic diaphragm pumps. Each type is designed with different features such as flow rate, pressure rating, material compatibility, port sizes, and other considerations.

How Diaphragm Pumps are Made

Diaphragm Pumps typically consist of a housing with two chambers separated by an elastic diaphragm made from various materials such as rubber or plastic. As the two chambers move against each other they create suction on one side and pressure on the other side which moves liquid or gas through the pump.

Industries that use Diaphragm Pumps

Diaphragm Pumps are widely used across many industries including oil & gas production and refining; chemical processing; food & beverage production; water treatment plants; paper mills; power plants; waste management facilities; agriculture operations; automotive manufacturing plants; pharmaceuticals production sites; fire suppression systems installations; paint shops & coatings facilities among others.
