Frequently Asked Questions
What types of rubber diaphragms do you manufacture for industrial applications?
We manufacture fabric-reinforced, PTFE-laminated, control valve actuator, PRV, rolling, and metal-to-rubber bonded diaphragms for pumps, actuators, regulators, and industrial equipment.
What is the difference between homogeneous and fabric-reinforced rubber diaphragms?
Homogeneous diaphragms are made entirely from rubber and offer high flexibility. Fabric-reinforced diaphragms contain fabric layers for greater strength and dimensional stability under higher pressure and repeated flexing.
Can you manufacture custom rubber diaphragms according to client drawings or physical samples?
Yes. We manufacture custom rubber diaphragms according to technical drawings, CAD files, specifications, or physical samples, including required dimensions and hardness.
How do I request a quotation for custom rubber diaphragms?
Provide the drawing or sample details, operating temperature and pressure, media, material requirements, reinforcement type, and required quantity to receive a quotation for custom rubber diaphragms.
