Diaphragms

Gulf manufactures high performance fabric reinforced diaphragms. These flexible seals transmit fluid pressure but not the fluid itself. They are used in pressure switches, flow regulators, pumps and fluid control valves.

What makes Gulf diaphragms different

Customisation

We can produce diaphragms to handle a range of fluids (such as water, gas and fuel) and service conditions (including chloramine resistance in potable water, resistance to automotive fluids such as fuel, refrigerant, engine oil, brake and transmission fluid).

Superior design

Our diaphragms are designed with low activation forces, linear activation function and high levels of reliability and repeatability.

Precision engineering

We specialise in manufacturing diaphragms where dimensional control and guaranteed material properties are crucial.We can manufacture diaphragm walls that are as thin as 0.2mm.

Zero defects

Our automated inspection systems guarantee the zero defect manufacture for critical applications, such as appliance pressure switches and automotive fuel regulators.

Rigorous testing

We put our diaphragms through rigorous in-house testing to ensure good long term performance in the areas of stress relaxation, heat and fluid ageing, and ozone and chloramine resistance.

Versatility

We are expereinecd in using a range of different elastomers including natural rubber, SBR, NBR, EPDM, silicone, fluoroelastomer, fluorosilicone, polyurethane and polyacrylate.

International approvals

Our diaphragms meet a range of international potable water approvals.
