Acknowledged as one of India’s premier AODD pump manufacturer, Mandar pumps offer a number of advantages that make them perfect for an almost endless variety of uses. Since Mandar pumps are air operated, they can be used in hazardous areas or for flammable materials. These pumps are of Bolted type which makes their maintenance very easy.

Mandar Pneumatic Double Diaphragm Pumps/ AODD pumps : Principle of Operation

It is a positive displacement pump which uses compressed air to move the diaphragms in a reciprocating manner. This movement is referred to as the Stroke of the diaphragm and can be understood as follows

LEFT STROKE

There is an air valve assembly whose function is to direct the pressurized air to the back side of diaphragm ( in this particular diaphragm referred as A). The diaphragm also separates the liquid media from the compressed air The diaphragm moves away from the centre due to this compressed air. At the same time, the opposite diaphragm is pulled in by the connecting shaft. Diaphragm B is on its suction stroke; The air behind the diaphragm is vented out to the atmosphere through the exhaust port of the pump.

The movement of diaphragm B toward the center creates a vacuum within chamber B. This causes the fluid to be forced into the inlet manifold due to atmospheric pressure, forcing the NRV ball off its seat. Liquid moves past the NRV ball and fills the liquid chamber (see shaded area).

MID STROKE

Once the diaphragm A reaches the limit of its discharge stroke, the air valve automatically redirects the pressurised air to the back side of diaphragm B. This forces diaphragm B away from the center while pulling diaphragm A to the center

Now Diaphragm B is on its discharge stroke. It forces the inlet NRV ball onto its seat due to the pressure developed in the liquid chamber and manifold of the pump. This same pressure lift the discharge NRV ball off its seat, while the opposite discharge NRV ball is forced onto its seat, forcing fluid to flow through the pump discharge. The movement of diaphragm A toward the center of the pump creates a vacuum within liquid chamber A. Atmospheric pressure forces fluid into the inlet manifold of the pump. The inlet NRV ball is forced off its seat allowing the fluid being pumped to fill the liquid chamber.

RIGHT STROKE

At completion of the stroke, the air valve assembly again redirects air to the back side of diaphragm A, which starts diaphragm B on its exhaust stroke. As the pump reaches its original starting point, each diaphragm has gone through one exhaust and one discharge stroke. This constitutes one complete pumping cycle.

Advantages of using Mandar AODD pumps

1. It Can Run Dry - This is a very useful capability. Many a time the liquid source runs dry eg Liquid gets over in barrel or tank and the pump keeps running. Centrifugal and other types of pump get heated up and may burnout whereas AODD pumps can function without any problem. Even if the discharge is blocked or shut off for some reason, It is just stop running without any damage.

2. AODD pumps are Self-Priming - It can be used where negative suction is needed. Hence AODD pumps are commonly used for drawing liquids from barrels and underground tanks. It is also function as sump pumps

3. It can handle Solids - The ball & Valve seat design enables AODD pump to handle liquids with solid particles in them. It can handle liquids with suspended powders or small particle. It can easily and efficiently handle anything from water to 70% solids

4. Easily Variable Speed - Varying of air supply to the AODD pump will vary the flow rate and changing the inlet pressure will change the discharge pressure of the AODD pump. It offer the ability to vary flow from 0 to full flow and discharge pressure up to 6 Bars with a simple adjustment of the air supply.

5. No mechanical seals - It do not have mechanical seasl thus eliminating all problems caused due to them such as leakage.

6. Ease of Maintenance - are considered as the most easy to repair. They do not require any special tools. Any person can easily replace the parts and repair the AODD pump.

7. Inherently Flameproof - Since the AODD pumps operate on air they can be considered as inherently safe for use in such environments. It is most popular in industries which handle Solvents like Printing and Packaging, Paints, as also where fuels like Petrol, Diesel are used.

8. On demand operation - It Can operate "on demand " without expensive pressure relief and bypass accessories

9. Shear Sensitive Liquids - It can pass even large, shear-sensitive solids without degradation or heat buildup transferred to pumped medium
