A diaphragm pump, also known as a membrane pump, is simply a pump that moves fluid.
They're highly versatile creations: they can be used in anything from wastewater treatments to the production of artificial hearts.
And you know the filter on your little aquarium at home? Diaphragm pumps help make those things as well-specifically, the part of the filter that pumps air).
In a diaphragm pump, the diaphragm is often made out of Teflon.
When it's squeezed, it pushes fluids either out one side or out both sides.
(This squeezing can be powered by electricity, or through a series of cranks and gears.
) As the diaphragm moves upward the pressure inside the device goes down, and so fluid is allowed to enter into the storage chamber.
The fluid will stay there until the diaphragm begins to move down, at which point the pressure inside the fluid chamber goes up and works to expel the fluid.
Then the diaphragm will move upward again, the pressure will drop once more, and so more fluid enters.
This creates a cycle of fluid moving in and out, and the moving parts of this cycle create force.
(This is kind of how an internal combustion engine works as well; the physics are very similar.
) There are several companies that make diaphragm pumps.
Among the leading companies are U.
S.
Plastic Corporation headquartered in Lima, Ohio; the Bosworth Company out of Providence, Rhode Island; and Ryan Herco Flow Solutions, which has offices in various cities throughout the United States.
When you're in the market to buy a diaphragm pump, be sure you know exactly how big it will have to be (tiny pumps, by the way, are known as micro-diaphragm pumps), how much suction lift you'll want, and what materials you'll want it to be made out of, if you have a preference.
You'll also have to decide what the flow rate should be.
The flow rate of a diaphragm pump depends on the length of the apparatus's stroke and the diameter of the diaphragm itself.
You'll also want something that's sturdy and long-lasting.
A good pump should be able to process thick liquids, and liquids like slurry that contain high concentrations of solid waste matter.
They should also be able to prime themselves.
Take all of these elements into consideration and you'll find yourself with diaphragm pumps that will service you and your needs for a long time.
