What is a diaphragm pump? Types of diaphragm pumps?
A diaphragm pump is a type of positive displacement pump that uses a flexible diaphragm to move fluid in and out of a pumping chamber. The diaphragm, typically made of rubber, thermoplastic, or Teflon, moves back and forth by an actuator, which can be mechanically, hydraulically, or pneumatically operated. As the diaphragm moves up, it creates

Improving Compressed Air System Performance
Energy savings from system improve-ments can range from 20 to 50 percent or more of electricity consumption. For many facilities this is equivalent to thousands, or even hundreds of thousands of dollars of potential annual savings, depending on use. A properly managed compressed air system can save energy, reduce maintenance, decrease downtime,
Expansion Tanks | Armstrong Fluid Technology
Description. Armstrong Expansion Tanks are designed to reduce tank sizes by up to 80% over standard designs. Expansion tanks use compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools. Diaphragm or bladder tank designs isolate the expanded water from the pressure controlling air
Understanding Your Pressure Storage Tank
One way to select the proper size for a pressure tank is to base it on the pump''s flow rate. A typical private water supply pump supplies water at a rate of 5 to 10 gallons per minute (gpm). Multiply the flow rate by four to determine the size of a diaphragm or bladder tank. For example, a 9-gpm pump would require a 36-gallon storage tank.
Compression Tank and Expansion Tank Selection Examples
When you use a plain compression tank with no bladder or diaphragm, the initial pressure is 0 PSIG or 14.7 PSIA. When you use a bladder or diaphragm tank, the initial pressure should be equal to the fill pressure at the tank location. This means the tank has to be charged on the air side to the proper fill pressure before being filling the tank.
Gaseous Hydrogen Compression | Department of Energy
Gaseous Hydrogen Compression. Hydrogen is typically produced at relatively low pressures (20–30 bar) and must be compressed prior to transport. Most compressors used today for gaseous hydrogen compression are either positive displacement compressors or centrifugal compressors. Positive displacement compressors can be reciprocating or

Expansion and Compression Tanks
Choosing to use a Bell and Gossett ASME bladder style expansion tank, ASME diaphragm style tank, or ASME standard compression tank in your hydronic system will depend on several factors. One important consideration in choosing which tank to use depends on the type of "air control" system you design.

Diaphragm tanks in buildings | Grundfos
Diaphragm tanks are commonly used on the discharge manifold to provide water storage for the system in very low flow situations. It decreases the running time of the booster pumps, thereby making the system more energy effective. Since the diaphragm is flexible, it is able to adjust to sudden pressure changes, thus counteracting water hammering.
Types of Expansion Tanks | PPT
AI-enhanced description. There are four main types of expansion tanks: open, plain steel, bladder, and diaphragm. Open tanks are not commonly used due to corrosion issues. Plain steel tanks have air in direct contact with water which can cause corrosion problems and require a larger tank size. Bladder and diaphragm tanks
