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 ...

Common questions about Diaphragm Pump

No matter what new developments happened in the world of air operated diaphragm pumps, there are certain questions that never change. Here, we’ll resolve some of the most frequently asked questions about air operated diaphragm pumps. 1. HOW DO I KNOW WHICH TYPE OF AIR OPERATED DIAPHRAGM PUMP TO BUY? While this seems like a loaded question, there are only five things you need to know when selecting the right pump for your application. Fluid: The type & composition of the fluid you plan to pump is the most important factor while choosing a air operated double diaphragm pump . In order to avoid wear & tear or corrosion, determine the fluid chemical makeup & consistency. Is it a clean fluid / slurry? Viscosity: Fluid viscosity is a very important factor while selecting a diaphragm pump. To provide some perspective, at All-Flo, eight out of ten customers are pumping fluid less viscous than motor oil. Flow rate: In order to select the appropriate pump, it is most importa...

Useful information on positive displacement pumps

What is a positive displacement pump? A positive displacement pump moves fluid by repeatedly enclosing a fixed volume & moving it mechanically through the system. The pumping action is cyclic & can be driven by pistons, screws, gears, rollers, diaphragms or vanes. How does a positive displacement pump works? Although there are a wide variety of pump designs, the majority can be placed into two different categories:  reciprocating  &  rotary . Reciprocating positive displacement pumps A Reciprocating Positive Displacement pump works by the repeated back & forth movement of a piston, plunger or diaphragm. These cycles areas also called as  reciprocation . In a piston pump, the first stroke of the piston creates a vacuum, opens an inlet valve, closes the outlet valve & draws fluid into the piston chamber (the  suction  phase). As the motion of the piston reverses, the inlet valve, now under pressure, is closed ...

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...
