Diaphragms are an excellent seal of choice for a variety of hydraulic and pneumatic applications, and are commonly used as seals in pumps, air brakes, dispensing and metering systems, pressure switches, flow meters, and valves and valve actuators.
We specialise in the design and manufacture of rolling “Top Hat”, convoluted and dished diaphragms in single acting or double acting format.
Materials
We supply elastomer and plastic diaphragms, specialist combination materials such as over moulded elastomer to thermoplastic diaphragms, and rubber with fabric reinforced diaphragms.
Elastomers include; Nitrile (NBR), Silicone (VMQ), Fluorocarbon (FKM), Chloroprene (CR), Ethylene Propylene Diene Monomer (EPDM), Polyacryate (ACM), Hydrogenated Nitrile (HNBR), Perfluoroelastomers (FFKM)
These elastomer materials are available in a single layer or double layer format, bonded with the following fabric materials: Polyamide (Nylon), Polyester, Nomex®,Vectran™.
We also manufacture diaphragms in PTFE for applications that demand materials with high chemical resistance or that require FDA approval or compliance.
For applications where good abrasion resistance and flex durability is required, we can manufacture diaphragms in a range of TPE materials including Hytrel, Santoprene and Polyurethane. These materials offer good tensile strength and do not require fabric reinforcement.
