Diaphragm Products Fabric Reinforced Single-Coat Diaphragms

Bellofram’s fabric reinforced single-coat diaphragms are engineered for high-performance sealing and pressure regulation in a variety of mechanical systems. These specialized reinforced diaphragms incorporate a durable layer of fabric into the elastomer during the molding process, resulting in a strong yet highly flexible component capable of withstanding demanding operating conditions.

The inclusion of fabric reinforcement enables the diaphragm to maintain flexibility while significantly increasing its pressure resistance. This added strength allows the diaphragm to perform reliably in dynamic applications where pressure fluctuations and mechanical movement are frequent. The result is a fabric reinforced rubber diaphragm that offers both flexibility and structural integrity — a balance that’s essential in systems requiring precise control and durability.

Our single coated diaphragms enhance responsiveness while minimizing weight and thickness, which can be critical in sensitive or space-constrained assemblies. Bellofram’s molding process ensures that the fabric layer is evenly integrated, avoiding inconsistencies that could compromise performance.

Customizable Fabric Reinforced Diaphragms for Varied Applications

These fabric reinforced single-coat diaphragms are highly customizable, with nearly all elastomer types available. Whether you need EPDM, nitrile, neoprene, or FKM diaphragms for enhanced chemical and temperature resistance, we can tailor the construction to meet your specific environmental and performance requirements. Our FKM seals are particularly well-suited for use in aggressive chemical environments or elevated temperatures where traditional elastomers may fail.

The reinforced construction also reduces the risk of ballooning or rupture under pressure, making these diaphragms ideal for long-term use in critical applications. In addition to strength and flexibility, the fabric layer improves dimensional stability, allowing for consistent, repeatable movement — key for accurate actuation and control.

Standard and Custom Single-Coated Diaphragm Solutions

Bellofram offers both standard and custom reinforced diaphragms, working closely with engineers and designers to create the optimal geometry, thickness, and material formulation for each use case. Whether you require small production runs for prototyping or high-volume manufacturing for OEM applications, we’re equipped to deliver quality and consistency.

With proven performance, excellent pressure tolerance, and broad material compatibility, Bellofram’s fabric reinforced single-coat diaphragms provide the versatility and reliability needed across a wide range of industries — from industrial automation to aerospace and beyond.
