An Air Operated Diaphragm pump, also known as a pneumatic diaphragm pump, is a type of positive displacement pump that uses compressed air as its power source. It consists of a diaphragm that is driven by an air motor, which causes the diaphragm to move back and forth, creating suction on one side and discharge on the other.

One of the main advantages of air operated diaphragm pumps is their versatility. They can handle a wide range of fluids, including abrasive, corrosive, and viscous materials. They are also capable of operating in hazardous environments, as they do not generate any sparks or flames.

Air operated diaphragm pumps are commonly used in a variety of industries, such as chemical, pharmaceutical, food and beverage, and water treatment. They are often used for transferring and metering fluids, as well as for pumping and transferring sludges and slurry-like materials.

There are several types of air operated diaphragm pumps available, including single acting, double acting, and airless. Single acting pumps have one air chamber, while double acting pumps have two air chambers that work in tandem to create a pumping action. Airless pumps do not use compressed air, but instead rely on a mechanical linkage to drive the diaphragm.

In terms of maintenance, air operated diaphragm pumps are relatively easy to maintain, as they have few moving parts and do not require lubrication. However, it is important to regularly inspect and replace worn or damaged parts to ensure optimal performance.

Overall, air operated diaphragm pumps are a reliable and efficient choice for a variety of fluid handling applications. They offer a safe, versatile, and cost-effective solution for transferring and pumping a wide range of fluids.

Features

__________________________________

Dual Diaphragms: AODD pumps feature two diaphragms that reciprocate back and forth to move the fluid, which ensures a consistent flow rate and prevents leakage.
Air-Powered: AODD pumps are powered by compressed air, which makes them suitable for use in hazardous environments where electricity cannot be used.
Self-Priming: AODD pumps are self-priming, meaning they can operate without a continuous flow of fluid, which reduces the risk of dry running and pump damage.
Easy Maintenance: AODD pumps have a simple design, with few moving parts, making them easy to maintain and repair.
Versatility: AODD pumps are suitable for a wide range of fluids, including viscous and abrasive materials, and can handle solids without clogging or damage.
Variable Flow Rates: AODD pumps have adjustable flow rates, allowing for precise control of fluid transfer and dispensing.
Portable: AODD pumps are often lightweight and portable, making them ideal for temporary or remote pumping applications.
