Introduction

Air operated double diaphragm pumps (AODD pumps) are versatile and efficient pumping solutions used across various industries. These pumps are renowned for their ability to handle a diverse range of fluids, including corrosive, abrasive, and viscous liquids. In this article, we will delve into the working principles of AODD pumps and explore the geotextile solutions offered by Depamu Company.

Working Principle of Air Operated Double Diaphragm Pumps

AODD pumps operate using compressed air as their power source. The pump consists of two diaphragms made of flexible materials, which are connected by a shaft. When compressed air is supplied, it moves from one chamber to another, causing one diaphragm to push fluid out while the other draws fluid in. This alternating action creates a continuous flow of liquid.

Key components of AODD pumps include:

• Diaphragms: These are the heart of the pump, typically made from materials such as PTFE, neoprene, or nitrile, depending on the chemical compatibility required.
• Air Valve: This directs compressed air to either diaphragm, facilitating the reciprocating motion.
• Ball Valves: Positioned at the pump’s inlet and outlet, these valves ensure fluid moves in the correct direction, preventing backflow.
• Manifold: This distributes the fluid between the pump inlet and outlet.

Advantages of Air Operated Double Diaphragm Pumps

AODD pumps offer several benefits, making them a preferred choice in many applications:

• Versatility: Capable of handling a wide range of fluids from water to highly viscous materials.
• Self-Priming: They can run dry without damage, which is advantageous for applications where the pump needs to clear air from the lines before starting.
• Explosion-Proof: Not relying on electricity makes them suitable for hazardous environments.
• Easy Maintenance: Fewer moving parts result in lower maintenance costs and downtime.
