Applications And Benefits Of PTFE Products


Polytetrafluoroethylene (PTFE) is a form of thermoplastic resin that is resistant to practically most of the corrosive services. It is one of the best materials for diaphragm pump because of its chemical stability and resistance.

Polytetrafluoroethylene (PTFE) is a durable and flexible elastomer of average tensile strength but remarkable chemical resistance, as well as excellent thermally and electrically resistive properties. At a molecular level, PTFE consists of a chain of carbon atoms with two fluorine atoms bonded to each carbon. These fluorine atoms surround the carbon chain, creating a dense molecule with very strong carbon-fluorine bonds and a polymer structure that is inert to most chemicals.
PTFE diaphragms have been one of the most thriving components that have lead to a breakthrough in the pump industry. They have been widely produced and are extremely successful in various industries across the globe. Following the pump industry:

A peristaltic pump or hose pump is a type of positive displacement pump used in various industrial applications for pumping variety of fluids. The fluid is contained within a flexible tube (i.e Hose) fitted inside the pump casing having no contact with any other part of the industrial hose pump. A rotor having rollers attached to the external circumference compresses the flexible tube in the peristaltic pump. As the rotor revolves, compression motion forces the fluid to move through the tube.

Applications or Uses of PTFE Diaphragm:

The PTFE the diaphragm has been widely accepted by all the consumers because of its stability and resistance. However, the most common consumers of the diaphragm are:

Neoprene: 

An excellent general purpose diaphragm for use in nonaggressive applications such as water-based slurries, well water or sea water. Exhibits excellent flex life and low cost.

Buna-N: 

Excellent for applications involving petroleum/oil-based fluids such as leaded gasoline, fuel oils, hydraulic oils, kerosene, turpentine, and motor oils.

EPDM: 

Excellent for use in applications requiring extremely cold temperatures. It may also be used as a low-cost alternative for pumping dilute acids or caustics.

Viton: 

Excellent for use in applications requiring extremely hot temperatures. Viton may also be used in aggressive fluids such as aromatic or chlorinated hydrocarbons and highly aggressive acids. PTFE would normally be used with these aggressive fluids as its flex life are better than Viton; however, in applications involving SUCTION LIFT (meter) outside the range of PTFE, Viton will be the the preferred choice for highly aggressive fluids.

PTFE: 

Excellent choice when pumping highly aggressive fluids such as aromatic or chlorinated hydrocarbons, acids, caustics, ketones, and acetates.

Benefits of PTFE Diaphragm Over Other Materials Are:

·        Intense heat resistance
·        Intense chemical resistance
·        Intense steam resistance
·        Lowest coefficient of friction
·        Partially Flexible
·        Non-toxic
·        Odorless and tasteless
·        Can be sterilized
·        Steam-proof
·        FDA approved for food applications

Air Operated Double Diaphragm (AODD) Pump Guide | Antliaworks

Air Operated Double Diaphragm (AODD) Pump Guide | Antliaworks Air Operated Double Diaphragm (AODD) pumps have a range of applications across various industries. Here, we shares the tips and tricks he’s picked up when it comes to maintaining AODD pumps. AODD pumps are the real workhorses of the industrial pump world and are used in a wide range of industries. These include chemicals, food processing, paints, electronics, road construction, maintenance for industrial processes, electricity production facilities, food processing, wastewater and sludge processing, and mining.They are self-priming, will run dry without doing any damage and use no electricity. Powered completely from compressed air, they are used in applications where electricity is not available or must not be used, such as hazardous or explosive situations or at remote sites.

OPTIMIZING USAGE OF AIR IN AODD PUMPS

In the industrial areas, there are some important operational costs – whether in the chemical processing, food & beverage, oil & gas, pharmaceutical, or mining industries – are the ones incurred for the purchase, operation & maintenance of pumps used during different production & transfer. One hidden component from the operating-cost perspective is the electricity used by double diaphragm pump , as per a study done by the Hydraulic Institute, account for nearly 20 percent of the world’s electricity demand. Assuming 7 cents per kilowatt/hour that equates to approximately $294 billion to operate diaphragm pump. Therefore, energy consumption can make up close to 90 percent of the total life-cycle costs of owning & operating a pump. Approximately 30 to 50 % of the energy consumed by pump systems can be saved by using air operated double diaphragm pump. Considering all the usage estimates, simple calculation reveals that up to $147 billion of electricity costs ...

Double Diaphragm Pump

What’s a double diaphragm pump? An air worked double diaphragm pump (also known as a Double-Membrane pump, pneumatic diaphragm pump or air-worked diaphragm pump) is a positive displacement pump that utilizes a mix of the responding activity of an elastic, thermoplastic or Teflon/pate diaphragm and appropriate valves on either side of the diaphragm (check valve, butterfly valves, fold valves, or some other type of stop valves) to pump a fluid. Diaphragm Pumps also known as Air Operated Double Diaphragm Pump ( AODD pump ), is a sort of responding positive displacement pump in which fluid is pumped by a responding diaphragm, which is driven by a solenoid, mechanical drive, or fluid drive. Different forms are air worked Pump has inlet & outlet check values. Diaphragm pump has great dry running qualities; they can be up to 97% effective. Diaphragm Pumps can deal with exceedingly thick fluids. A double diaphragm pump is known as a positive displacement pump. It utilizes t...
