Numatic Pumps Diaphragm Pump is of a bolted type and offers a number of advantages that make them perfect for an almost endless variety of uses. PP Air Operated Double Diaphragm Pumps are air operated, they are used in Hazardous, Acidic and Flammable areas.
A Diaphragm Pump is a positive displacement pump that pumps fluid by combining the reciprocating action of a rubber, thermoplastic, or Teflon Diaphragm with appropriate valves on either side of the Diaphragm (check valves, butterfly valves, flap valves, or any other type of shut-off valves).
In a Diaphragm Pump, the Diaphragm is sealed with one side immersed in the pumped fluid and the other in air or hydraulic fluid. When the diaphragm flexes, the volume of the pump chamber increases and decreases. A pair of non-return check valves prohibit the fluid from flowing backwards. When the capacity of a Diaphragm Pump chamber is expanded (by pushing the diaphragm up), the pressure drops and fluid is sucked into the chamber. When the chamber pressure rises as a result of the lower volume (due to the diaphragm sliding down), the fluid that was previously sucked in is driven out. Finally, when the diaphragm rises, fluid is drawn into the chamber, completing the cycle. This movement is comparable to that of a cylinder in an internal combustion engine. Diaphragm Pumps provide an airtight seal between the driving mechanism and the compression chamber, allowing the pump to transport, compress, and expel the medium without the use of lubrication.
PP (polypropylene) AODD (air-operated double diaphragm) pumps are a type of positive displacement pump that are designed to handle a variety of fluids, including corrosive and abrasive materials. The pumps are constructed of polypropylene, a thermoplastic polymer that is known for its excellent chemical resistance and durability.
AODD pumps are powered by compressed air and use a diaphragm to transfer fluid from the suction side of the pump to the discharge side. The diaphragm is made of a flexible material that is able to expand and contract as air is alternately introduced to and removed from the pump chambers.
PP AODD pumps are commonly used in industrial and chemical processing applications, as well as in the transfer of food and beverage products. They are popular because of their versatility, ease of maintenance, and ability to handle a wide range of fluid viscosities and temperatures.
When selecting a PP AODD pump, it is important to consider factors such as flow rate, pressure, and the specific characteristics of the fluid being pumped. Proper installation, operation, and maintenance of the pump are also critical for ensuring optimal performance and longevity.
