Fabric Rubber Diaphragm For Pump Valve

Core Functions

• Dynamic sealing: As a flexible barrier, the diaphragm responds to pressure changes by deforming to precisely control the flow direction, flow rate, and pressure of the fluid (liquid or gas). For example, in a pneumatic valve, the up and down movement of the diaphragm directly opens and closes the flow channel.

• Pressure resistance and durability: Fabric reinforcement allows the diaphragm to withstand pressures up to 50 psi (some designs can reach 10 bar) and maintain a long life under frequent expansion and contraction.

• Isolation and protection: Prevent the medium from direct contact with the mechanical parts of the pump and valve to avoid corrosion or contamination, while absorbing vibration and shock.

Structure and Materials

•   Rubber matrix: usually natural rubber (such as NBR) or synthetic rubber (such as EPDM, chloroprene rubber, and FKM), with elasticity, chemical corrosion resistance, and temperature adaptability.

•  Fabric reinforcement layer: by embedding multiple layers of woven fibers (such as nylon, and polyester) to form a mesh structure, the tear strength, compressive resistance, and dimensional stability of the diaphragm are significantly improved. For example, nylon-reinforced nitrile rubber diaphragms can maintain performance under frequent bending.

•  Special design: Some diaphragms are also combined with metal inserts or PTFE coatings to adapt to extreme chemical environments or high-pressure conditions.

Application Scenarios

1. Pumps: such as pneumatic double diaphragm pumps (AODD), which use the reciprocating motion of the diaphragm to achieve leak-free delivery of abrasive slurries or chemicals.

2. Valves: used for regulating valves, solenoid valves, or diaphragm valves. For example, some solenoid valves use reinforced rubber diaphragms to reduce pressure loss and adapt to turbid media.

3. Industrial Fields: covering petrochemicals, pharmaceuticals, food processing, etc., especially in scenarios that require corrosion resistance, high-temperature resistance, or hygiene standards.
