Product Specifications
Material Scope Material Scope
Rubber Diaphragms with Fabric Reinforcement -Western Rubbers can manufacture rolling diaphragms in a range of elastomers like Silicone, EPDM, FKM, Nitrile, etc. Each elastomer comes with its unique properties.Rolling diaphragms have a high strength fabric reinforcement layer sandwiched between two elastomeric layers, thus ensuring maximum strength and durability. This fabric layer not only offers high tensile strength to the diaphragm, but is also designed to permit smooth rolling action of the diaphragm.
Need For Rolling Diaphragms Need For Rolling Diaphragms
Rolling diaphragms find their application in industries that require high performance in harsh environments, such as the chemical processing, automotive, food and beverages, aerospace and medical industries. Known for their accurate, repeatable positioning, rolling diaphragms can offer long stroke lengths, and no spring rate, i.e. the force caused by rubber trying to return to its molded position.The rolling diaphragm rolls and unrolls alternately on the piston skirt and cylinder wall. A semi-circular "convolution" in the diaphragm is formed between the piston and cylinder wall. This convolution rolls as the piston moves up and down. The rolling action is smooth and eliminates sliding contact and breakaway friction. It forms a perfect barrier, preventing leakages and pressure loss. A variety of flange designs for diaphragms are available depending on the application.

Types Of Rolling Diaphragms Types Of Rolling Diaphragms
Type 1: Flat Flange Diaphragms - Flat flange diaphragms are the most commonly manufactured rolling diaphragms. Applications that have flat mating surfaces between the cylinder and the piston prefer the installation of these diaphragms. The flanges of the diaphragms basically serve as a sealing gasket to prevent leakages at the parting section.Type 2: Crimped Diaphragms - Crimped diaphragms need not be inverted at the time of installation since the convolution is molded in the "as-installed" configuration. Since it is not economical and practical to manufacture diaphragms with deep convolutions, Crimped Diaphragms have a limited stroke suitable for applications with limited strike length.Type 3: Beaded Flange Diaphragms - Beaded flange diaphragms have a flange which looks similar to an O-ring. The diaphragm is sealed via axial compression of the D shaped bead. The application for these diaphragms is configured in a way so as to provide for installation of the bead in a mating groove. Owing to the principles of compression set, the D shaped bead might lose some of its effectiveness with time and use at high pressures. And hence, this design is not recommended for applications where the differential pressures could exceed 10 bar.Type 4: Beaded Flange Crimped Diaphragms - Beaded flange crimped diaphragms combines the properties of both Type 2 and Type 3 diaphragms. These diaphragms are also molded in the "as-installed" configuration and hence do not require inversion at the time of assembly. Since no inversion is required, a flat retainer plate is sufficient to retain the head of the diaphragm to the piston.Type 5: Internal Beaded Flange Diaphragms - The internal beaded flange diaphragms comprise of a rectangular bead running internally around the circumference of its mounting edge. This configuration offers a minimum outside housing diameter. Since the flange bead is on the inside of the cylinder, this stroke capability of the diaphragm is usually restricted to half stroke.
