Rubber Diaphragms

Diaphragm Types

Rubber Diaphragms are flexible seals that prevent
unwanted transmission of substances between two
places. These substances can be liquids, gasses
or solutions. They are characteristically tough
and dynamic and essential in many flow control
applications.

1. Fabric Reinforced Diaphragm

• The diaphragm utilizes a layer of fabric
  during the molding process.  This offers a wide
  range of design flexibility.  The fabric allows
  the diaphragm to withstand higher pressures whle
  also remaining very flexible in the process.  All
  elastomers can be constructed as a fabric
  reinforced diaphragm.

2. Double Coated Diaphragm

• Some diaphragm applications require that the
  rolling diaphragm be coated with rubber on both
  sides. This type of diaphragm is typically
  required when the application sees pressure on
  both sides of the diaphragm.

3. Insert Bonded Diaphragms

• Western Rubber has the ability to bond
  metal or plastic inserts to the diaphragm during
  the molding process. During the process, the
  insert becomes totally or partial encapsulated by
  the elastomer. Thus, creating a strong bond
  between the two.  By using this bonding process,
  costly assembly operations can be eliminated.

4. All Rubber Diaphragms

• All rubber (homogeneous) diaphragms can be
  used if the strength factor of a fabric
  reinforced diaphragm is not necessary.  These all
  rubber diaprhagm are used in very low pressure
  applications. The same functionality of a fabric
  reinforced diaphragm applies to the all rubber
  diaphragms (just without the fabric).

5. Flat / Die Cut Diaphragms

• Western Rubber has the ability of producing
  flat / die cut diaphragms for the industry.
   Diaphragm can be all rubber, fabric reinforced
  or double-coat.  Various trim patterns are also
  an option for these flat diahpragms.

6. Teflon Faced Diaphragms

• Western Rubber has the capability of bonding
  a Teflon coating to the rubber diaphragm. This
  technique produces a diaphragm that is more
  suitable for harsh environments.
