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

Why AODD Pump.?

Today we will take a gander at why you should purchase an Air Operated Double Diaphragm Pump (AODD), what the points of interest are over other  Pump types and is it the correct Pump for you? Read on to discover.  B ut first, go through the  diaphragm pump working  to understand the advantages. AODD Pumps are utilized all through the mining business and are likewise normally found in concoction transportation/preparing and general applications.  What Makes an AODD so Special?  An  Air Operated Double  Diaphragm Pump  has a ton of focal points over other Pump plans. Beneath we drill down a portion of the benefits of AODD Pumps over against other Pump types. 1.  AODD Pump Has  the ABILITY TO RUN DRY No close fittings or sliding parts are at risk, therefore the pump can operate even when dry without massive damage. It is not recommended to dry run constantly or for long periods, due to the fact that one will consume the  diaphragm stroke life , however other than the diaph

Benefits of Air Operated Double Diaphragm Pumps

Understanding the Benefits and Applications of Air Operated Double Diaphragm Pumps An air operated double diaphragm pump (AODD) is a type of positive displacement pump that uses compressed air as the source of energy to move liquids. It consists of two flexible diaphragms that separate the pumping chamber from the air inlet and outlet. The air pressure causes the diaphragms to expand and contract, creating suction and discharge strokes that move the liquid through the pump. One of the key benefits of AODD pumps is that they are self-priming and can operate in both wet and dry conditions. They are also capable of handling liquids with high viscosities and solids, making them suitable for a wide range of applications. Additionally, they are simple in design and require minimal maintenance, making them a cost-effective solution for many industrial applications. AODD pumps are commonly used in a variety of industries, including chemical, food and beverage, pharmaceutical, and water treat

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 two d
