How long do diaphragm pumps last?

In general, diaphragms on metering pumps last about 6 to 12 months; gears on gear pumps last about 3 to 6 months; and motors usually last for years.

How much air does a diaphragm pump use?

Each full extension of a diaphragm is called a press stroke. The speed of the strokes impacts how much compressed air flow (in cfm) the AODD pump consumes. They typically run at 85 to 95 psi, depending on the application….

Can Aodd pumps run dry?

AODD pumps can run dry for an extended period of time without damaging the pump or its components. It’s very common for pumps to run dry. Other types of positive displacement pumps may be damaged by running dry, which shortens their service life and increases maintenance hours and cost.

Why do diaphragm pumps fail?

Running the pump dry is a common way that diaphragms will fail. It sounds pretty obvious, but very common. Another way diaphragms rupture is by operating the pump higher than maximum pressure ratings. Sometimes operators crank up the compressed air pressure to get the pump’s reciprocating action to work faster.

What is Aodd pump?

An AODD pump is a type of positive displacement pump that uses compressed air as a power source. The compressed air is shifted from one chamber to the other by a linked shaft that allows the chambers to move simultaneously.

How do I calculate the flow rate of my Aodd pump?

To get the gpm of your pump, multiply the number of strokes by the displacement per stroke. Flow rates can be controlled to produce from zero to maximum flow simply by increasing or decreasing airflow or pressure. Standard 1:1 ratio AODD pumps can produce pressures up to 125 psi (8.6 bar).

How does Aodd pump work?

What happens if a diaphragm pump runs dry?

Dry running an AODD will not have an immediate negative effect on your pump, but an AODD who runs dry will speed up. This will not only cause a bigger air consumption but the diaphragms will make a lot of strokes and will come to the end of their elasticity much quicker and will fail.

How much lift does a diaphragm pump have?

Height of Lift Normally, the suction lift of a diaphragm pump is limited to that corresponding to 14 feet of water at sea level. This amounts to a lift of approximately eight feet when pumping pulp containing 50\% solids when the specific gravity of the dry solids is 2.65.

How do aodd pumps work?

AODD pumps also feature only a few wetted parts that are dynamic: two diaphragms, which are connected by a common shaft, two inlet valve balls and two outlet valve balls. Driving the diaphragms with compressed air instead of the shaft balances the load on the diaphragm, which removes mechanical stress from the operation and extends diaphragm life.

Why ads for aodd?

Image 1. Advanced ADS technology can reduce the operating costs for AODD pumps in many industries including chemical processing, food and beverage, oil and gas, pharmaceuticals and mining. Happy customers and safe employees are typically easy to identify and measure.

How much does it cost to operate a pump?

Assuming 7 cents per kilowatt/hour, that equates to approximately $294 billion to operate pump systems. Therefore, energy consumption can make up close to 90 percent of the total life-cycle costs of owning and operating a pump.

What makes the Wilden ads 60 percent more efficient?

The incorporation of an innovative air control spool into the design of the new ADS is what gives it the ability to arrest air loss at the conclusion of each pumping stroke, which helps make it up to 60 percent more efficient than other ADS technologies.
