Pump Diaphragms: Overview
Saint-Gobain Composite Solutions offers a range of PTFE Film and Composite multi-layer solutions for valves and diaphragms tailored to the needs of specific industries. Dimensionally stable, thermally weldable, and with high tensile and tear strength they provide long-lasting, consistent performance. Excellent flex life and reduced permeability enhance lifetime, reduce contamination, and protect equipment.
Ultraflex VERSIV™ Multimaterial Composite has the highest flex life compared to regular PTFE (up to 200% higher) and its high flex resistance means it has a long mean time between failure. The non-stick washable surface saves time, material costs, and energy through low friction and easy-release properties. Additionally, thermal stability from -328˚F to 500˚F (-200˚C to 260˚C), electrostatic safety, and almost universal chemical resistance ensure high levels of safety.
Pump Diaphragm Applications
Pump diaphragms are used in a wide range of applications, such as chemical processing, pharmaceuticals, food and beverage processing, mining, and wastewater treatment, where reliable and efficient pumping of liquids is required. Saint-Gobain Composite Solutions VERSIV™ film and composite multi-layer solutions are used in pump diaphragm applications as the flexible barrier that separates the liquid or gas being pumped from the rest of the pump components.
Chemical Resistance & Flexibility and Durability
Chemical Resistance: PTFE films are highly resistant to chemicals, acids, and solvents. This makes them ideal for use in pumps that handle aggressive chemicals or corrosive materials. PTFE films can withstand a wide range of chemicals and are also resistant to hydrolysis, which makes them suitable for use in humid environments.
Flexibility and Durability: Our films are very flexible and can be formed into diaphragms that are thin and durable. They are also resistant to tearing and abrasion, which helps prolong their lifespan.
Low-Friction, Temperature Resistance & Reduced Maintenance
Low Friction: Our films have a very low coefficient of friction, which means they do not stick to other materials easily. This makes them ideal for use in pumps that handle viscous or sticky fluids.
High-Temperature Resistance: Our films can withstand high temperatures without degrading, which makes them suitable for use in pumps that handle hot fluids.
Reduced Maintenance: Because our films are durable and resistant to chemical attack, they require less maintenance than other materials, reducing downtime and saving on maintenance costs.
