What is a double diaphragm pump used for?
AODD pumps are generally used for transfer applications and can handle a wide variety of feeds including sludges, slurries, abrasive and shear sensitive fluids. Although they are robust, reliable and easy to maintain they can be noisy, prone to icing, and are limited to low pressure applications.
Where is diaphragm pump best suited?
Plastic diaphragm pumps are best suited for applications involving chemicals like acids, caustics, and bleach. Some chemicals are not suitable for plastic pumps such as styrene and certain resins like isocyanate and polyol.
Where do we use diaphragm pump?
Because diaphragm pumps are so versatile, they are used in virtually every industry that requires fluid transfer. They are often used for dewatering or water removal across many different industries. They are used for filling, dispensing and metering due to their efficiency and accuracy.
Are double diaphragm pumps self priming?
Diaphragm Pumps Are Self-Priming Unlike some other pumping technologies, AODD pumps are self-priming and don’t require positive inlet pressure to prime (flooded or needing a dry suction lift).
What are the advantages of a diaphragm pump?
Advantages of Diaphragm Pumps
- HANDLES A WIDE VARIETY OF FLUIDS WITH HIGH SOLIDS CONTENT:
- SELF PRIMING.
- ABILITY TO RUN DRY.
- EXPLOSION PROOF.
- PUMPING EFFICIENCY REMAINS CONSTANT.
- VARIABLE FLOW RATE AND DISCHARGE PRESSURE.
- CAN NOT OVERHEAT.
- NO MECHANICAL SEALS, COUPLINGS, OR MOTORS.
How much air does a double diaphragm pump use?
Most AODD pumps can operate at any air pressure, typically up to a maximum of 8.6 bar or 125 PSI. However, if the air supply is obstructed, the pump will lose its effectiveness.
How do you prime a double diaphragm pump?
To solve this priming issue in a matter of seconds, slow down the pump by using the air regulator to decrease the air pressure entering the air valve. Once the pump speed has been reduced and the fluid has had enough time to enter the pump, increase the air pressure and operate the pump at a faster speed.
What is the maximum discharge pressure on a diaphragm pump?
GENERAL PUMP INFORMATION
| Port Sizes | 3/4″ through 3″ |
|---|---|
| Discharge Pressure | Up to 180 PSI |
| Max. Size Solid | <13/32″ (10mm) |
| Construction Material | Stainless Steel, Cast Iron, or Aluminum wetted materials |
| Diaphragm Material | EPDM, Neoprene, Buna N, Viton®, Santoprene®, and Hytrel® elastomers |
Can diaphragm pumps run in reverse?
When this device is applied to diaphragm pumps or other types of pump, it allows to invert the flow direction; manually or pneumatically operated, inlet and outlet are reversed.
What happens if you don’t prime a pump?
If you don’t prime your pump, you risk mechanical seal failure, and further damage to other necessary pump components. Without proper priming, your water pump’s motor will still run, but you’ll notice low water pressure, or no fluid delivery at all.
What oil goes in a diaphragm pump?
The recommended oil for a Silvan Comet diaphragm pump is SAE 20W/30 Multigrade oil. this has less cushioning effect between the piston and the diaphragm.
