Rubber PTFE Diaphragm

The diaphragms Rubber / PTFE we offer are manufactured using qualitative raw material procured from trustworthy vendors. These are widely used in various industries and have gained huge accreditation in the industry for their host of exclusive features. The entire range can also be customized as per the specification detailed by the clients.

Rubber Diaphragms

A diaphragm is a flexible barrier that spans the gap between a moving and stationary units/members. The primary function of the diaphragm is to prevent fluid interchange between two separated chambers. Rubber diaphragm can be manufactured from a variety of rubber sheets.

CLASSIFICATION OF RUBBER DIAPHRAGMS

The diaphragms may be classified into two distinct types:

CLASSIFICATION OF RUBBER DIAPHRAGMS

The diaphragms may be classified into two distinct types:

STATIC DIAPHRAGMS

These diaphragms are used to separate two fluids and are subjected to little or no motion during their application. Also, they suffer very little pressure change during the process.

DYNAMIC DIAPHRAGM

Dynamic diaphragms act as sealing devices between a stationary and moving component of a system. Hence, they have to usually transmit force and pressure to maintain the balance.

TYPES OF RUBBER DIAPHRAGM

There are four types of rubber diaphragms which are primarily available in the market:

CLASSIC RUBBER DIAPHRAGMS

These rubber diaphragms are made of rubber, rubber-fabric combinations and specialty materials.

INDUSTRIAL RUBBER DIAPHRAGMS

These rubber diaphragms are resistant to many chemicals at different pressure ranges. These are movable between two components through a dividing membrane. The main functions of industrial rubber diaphragm include:

  • They are used to control the pressure in industrial settings.
  • They are used to make valves.
  • They are used for manufacture of pumps.
  • They are used for accumulator functions.

MOLDED DIAPHRAGMS

These diaphragms are made specifically based on the requirements given by the customers. The molded diaphragms are manufactured to be resistant to a huge range of pressure that is exerted on them during their application.

PROPERTIES OF ELASTOMER/RUBBER DIAPHRAGMS:

The rubber diaphragms have many distinct properties enabling their usage but some of the most useful ones are:

  • The rubber diaphragms can perform various functions over a broad range of operating temperature and conditions ranging from the metering of fuels to the regulation of gas for heating systems.
  • They have maximum thickness to provide maximum sensitivity.
  • They are built so as to avoid any sort of leakage which can be fatal in all its usage and hence, anti-wrinkle fabrics are used.
  • They have an extended life even when operating under high temperature range or close to flame.
  • The elastomer/ rubber diaphragms are considered to be dimensionally stable in all its vital applications.

USES OF RUBBER DIAPHRAGMS

Some of the most popular uses of rubber diaphragms are:

  • CNG/LPG vaporizers and reducers
  • Gas meters
  • LPG regulators
  • Fuel pumps
  • Pumps and valves
  • Automotive diaphragm
  • Fabric diaphragm
  • Actuator valves
  • Other purpose diaphragms

SELECTION OF RIGHT MATERIAL FOR THE RUBBER DIAPHRAGM

There are a wide range of elastomers available for the job but the right type should be chosen based on the job profile which consists of the following considerations:

  • Desired sensitivity
  • Working pressure
  • Distance from the flame or other conditions where is has to function.
  • Rate of diaphragm travel
  • Temperature
  • Smoothness of the flange areas
  • Flange pressure
  • Working environment

The diaphragms rubbers we manufacture are available in various sizes ranging from 5 mm to 1000 mm. Our range of diaphragms is manufactured using PTFE / ELASTOMERIC materials that have the capacity to withstand harsh weather conditions. We make use of almost all types of material that comprises of Nitrile, EPDM, Neoprene, Fluorosilicone, Silicone, SBR, Fluoroelastomers Viton.,PTFE.
