Rubber diaphragms are flexible rubber membranes, sometimes reinforced with fabric, strategically placed to prevent unwanted transfer of substances between two places by creating a seal. They can be used to separate two gasses, two liquids, or one gas and one liquid that should not mix. we can provide PTFE-bonded rubber diaphragms for use with aggressive chemicals, fabric reinforced rubber diaphragms for added durability, or high-tolerance thin walled rubber diaphragm.
How do rubber diaphragms work?
Pressure differences cause a rubber diaphragm to move up into a chamber or down into another chamber, enabling a degree of motion between a stationary and a moving part. Due to their low permeability to fluids and gases, rubber diaphragms maintain media separation on either side of the diaphragm. They also ensure a consistent pressure differential between the media and can provide gasket functionality in the flange of an instrument.
Rubber Diaphragm for Pharmaceutical Industry
The Pharmaceutical Industry is one popular segment that uses rubber diaphragms for various purposes.
Sterilisiability, Hygiene, processability, biocompatibility, bio-durability as well as mechanical properties, such as flexibility and resilience, are properties that make rubbers appropriate candidates for medical applications.
Rubber & PTFE diaphragms are used in a variety of medical, pharmaceutical & biotechnology applications, particularly in low-pressure valves. Most of the pharma companies use Silicone Rubber Diaphragms.
The operating conditions and the range of applications within the pharmaceutical market presents a challenging role for any sealing materials and seal products supplier to deliver an effective and comprehensive portfolio. Working within this environment requires attention to detail.
The production and packaging processing not only have to follow stringent regulations and quality control methods but also needs to be aware of the complexity of the operations within which the seal is required to perform.
Ami Polymer Pvt. Ltd. is one such rubber diaphragm manufacturer that offers a range of rubber products for Pharmaceutical Industry. Using superior quality rubber and cutting-edge techniques, these diaphragms are manufactured by skilled professionals.
The uniqueness of Ami Rubber Diaphragms is its performance in extreme conditions such as high pressure, high temperatures, and corrosive fluids. The team of experts design the diaphragms, taking into consideration all the extreme service conditions of the actual user and then specify the correct polymer, reinforcement and durometer hardness to achieve the highest result in performance, which in turn reduces the maintenance cost and shutdown timings. This makes it obvious that Ami Polymer Diaphragms are preferred by many OEM’s and Pharm companies.
Applications
Polytetrafluoroethylene-PTFE (Teflon) is an engineering thermoplastic resin that is practically resistant to all fluids. Of all our diaphragm materials, it is the most chemically resistant., PTFE can be used with media reaching very high temperatures up to 300° C. PTFE is popularly known as Teflon which is a Tradename of DuPont.
We specialize in PTFE lined Rubber Diaphragms (0.25mm, 0.5mm, 1.00mm lining thickness) as well as Pure PTFE Rigid (upto 3mm thickness) Diaphragms for all kind of Valves, pumps and actuators used in critical corrosive applications. The Rubber used with PTFE Linings are Neoprene and EPDM.
Our PTFE Lined Diaphragms are made from size ranging from 12mm to 200mm Diameter in various shapes as per clients’ requirement. Our Diaphragms have been tested upto 6kg/cm2 and operated upto a 1000 cycles. These diaphragms are not suitable for vacuum service and high pressures.
We design, develop, prototype PTFE Diaphragms as per your requirements/service conditions.
