THREE BIG ADVANTAGES OF AODD DIAPHRAGM PUMP

 Diaphragm pumps have very significant properties, which make them particularly suitable to be used in agriculture on spraying bars and air-blast sprayers. The three main advantages of a diaphragm pump compared to a pump are:

1. Excellent head and self-priming capacity.

2. Good dry running capacity

3. Resistance to abrasion and corrosion


The diaphragm pump working which uses alternating variations within the volume of a chamber (expansion and contraction) to get imbalances in pressure between the chamber and adjacent spaces.

Trying to catch up on the difference in pressure between two environments, the fluid naturally moves from the space with greater the pressure to space with lower pressure, leading to a downward movement, a rise, and briefly within the pumping of the fluid itself.

The expansion and contraction of the chamber volume that generate these pressure changes are obtained by means of the alternating flexing of the diaphragm.

The diaphragm is nothing quite a rubber disc screwed onto the piston which separates the pumping chamber from the transmission parts and prevents the pumped fluid from coming into contact with the mechanical parts and therefore the lubrication oil.

Thanks to the airtightness generated by the diaphragm and therefore the separation between the pumped liquid and the oil bath chamber, employing a diaphragm pump has three main advantages:

1. EXCELLENT HEAD AND SELF-PRIMING CAPACITY

The diaphragm pump has the power to make an honest vacuum on the suction line. In practice, the diaphragm generates a superb airtight seal and a uniform vacuum on the suction line, which suggests that a diaphragm Pump can lift fluids from levels less than those during which it's located (head capacity). Lifting between 3 and three .8 metres (9.8 and 10.5 feet) is normal for a diaphragm pump, with the apparent advantage of having the ability to draw liquids from the channels or basins below it and a huge benefit when loading tanks.

In addition, a diaphragm pump how it works, it often operated without the necessity to fill the suction pipe (unlike the centrifugal pump), because of the very fact that it's ready to suck up the air contained within the suction pipe during the start-up phase, and eliminate such air through the delivery line (self-priming capacity).

After having eliminated all the air, the pump operates normally.

2. GOOD DRY RUNNING CAPACITY

Thanks to the airtight separation between the pumping chamber and oil-bath lubricated transmission components, diaphragm pumps can withstand reasonable periods of dry running (e.g. when operating in self-priming mode or within the event of an opportunity within the suction line) without negative consequences, like overheating and seizing from connecting rods and pistons, which occur on centrifugal pumps that can't work dry.

3. RESISTANCE TO ABRASION AND CORROSION

Because there are not any mechanical parts indirect contact with the liquid (as we've said, the diaphragm creates an airtight seal between the pumping chamber and therefore the transmission components), the diaphragm AODD Pump can pump liquids that aren't perfectly filtered with residues of solid particles like crystals, sand or crushed stone (mechanical resistance) and maybe used with most water-based plant protection substances, including when mixed with acids, solvents, abrasive particles, sediments or slurry (corrosion resistance).

As you'll see from the image, the diaphragm separates in an airtight way the blue compartments, during which the pumped liquid flows, from the oil bath chamber during which the mechanical components are located (in yellow).

OPTIMIZING USAGE OF AIR IN AODD PUMPS

In the industrial areas, there are some important operational costs – whether in the chemical processing, food & beverage, oil & gas, pharmaceutical, or mining industries – are the ones incurred for the purchase, operation & maintenance of pumps used during different production & transfer. One hidden component from the operating-cost perspective is the electricity used by double diaphragm pump , as per a study done by the Hydraulic Institute, account for nearly 20 percent of the world’s electricity demand. Assuming 7 cents per kilowatt/hour that equates to approximately $294 billion to operate diaphragm pump. Therefore, energy consumption can make up close to 90 percent of the total life-cycle costs of owning & operating a pump. Approximately 30 to 50 % of the energy consumed by pump systems can be saved by using air operated double diaphragm pump. Considering all the usage estimates, simple calculation reveals that up to $147 billion of electricity costs ...

Double Diaphragm Pump

What’s a double diaphragm pump? An air worked double diaphragm pump (also known as a Double-Membrane pump, pneumatic diaphragm pump or air-worked diaphragm pump) is a positive displacement pump that utilizes a mix of the responding activity of an elastic, thermoplastic or Teflon/pate diaphragm and appropriate valves on either side of the diaphragm (check valve, butterfly valves, fold valves, or some other type of stop valves) to pump a fluid. Diaphragm Pumps also known as Air Operated Double Diaphragm Pump ( AODD pump ), is a sort of responding positive displacement pump in which fluid is pumped by a responding diaphragm, which is driven by a solenoid, mechanical drive, or fluid drive. Different forms are air worked Pump has inlet & outlet check values. Diaphragm pump has great dry running qualities; they can be up to 97% effective. Diaphragm Pumps can deal with exceedingly thick fluids. A double diaphragm pump is known as a positive displacement pump. It utilizes t...
