Boost Efficiency of your work with Macnaught High-Quality Air Operated Diaphragm Pump

How Air Operated Diaphragm Pump Work : A Complete Guide | Macnaught USA
Air Operated Double Diaphragm (AODD) pumps are extensively useful and reliable, used in a variety of industries. It is used in the chemical processing, food and beverage sector.How accurately do these pumps work? In this article, we'll discuss the parts of AODD pumps, how they work, and why they're the best choice for fluid handling applications
What is an Air Operated Double Diaphragm Pump?
An Air-Operated Double Diaphragm (AODD) pump is a positive displacement pump powered by compressed air. It has two flexible diaphragm Pumps   that move back and forth to create a reliable pumping action. 

AODD pumps are well suited for handling viscous, abrasive or shear-sensitive fluids, making them ideal for challenging industrial applications.

Air Operated Double Diaphragm Pump

Key Components of an AODD Pump

  • Two flexible membranes that move in unison are called diaphragms
  • Compressed air is directed to the diaphragms' opposing sides via an air valve
  • Verify the one-way fluid movement and prevent backflow by checking the valves
  • Pump chambers are used to pull in and release fluid

How Macnaught AODD Pump Works

The four-stage cycle that powers the Macnaught’s AODD Pump:-
  1.  Air Inlet Activation: Compressed air is received by the air valve, which directs it to one of the diaphragms
  2. Movement of the Diaphragm - Through a connecting shaft, the air pressure pulls the opposing diaphragm inward while pushing the first diaphragm outward
  3. The Suction Phase - Through the intake check valve, fluid is drawn into the pump chamber by the vacuum created when one diaphragm retracts
  4. Phase of Discharge - Via the output check valve, the opposing diaphragm forces fluid out of the other chamber. Rapid repetition of this cycle makes continuous and effective fluid transfer possible
