Diaphragms

Rubber diaphragm seals offer an ideal sealing solution where an accurate, consistent response is required for changes in hydraulic or pneumatic pressures with zero leakage, low friction, and no lubrication.

Products
Profiles include convoluted, dished and “top hat” designs in both single acting and double acting formats.
Materials
Rubber diaphragms, fabric reinforced elastomer materials, PTFE and TPE materials available.
Manufacturing
We can produce sizes as small as 12mm diameter and over 1000 mm in diameter.
Engineering & Design
Complete seal design service from experienced application engineers using the latest technology in 3D design and FEA simulation software.

About Diaphragms

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.
