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.

What problems can films solve in pump diaphragms?

Films can help solve several problems in pump diaphragms, including:
Chemical Resistance: VERSIV™ films can be used to provide a barrier layer between the pump diaphragm and the process fluid, which can help to protect the diaphragm from corrosive chemicals. This can help to extend the lifespan of the diaphragm and reduce maintenance costs.
Flexibility: Our films can be used to improve the flexibility and durability of pump diaphragms. By adding a thin film layer to the diaphragm, it can be made more resistant to fatigue and cracking, which can improve the overall performance and lifespan of the pump.
Contamination Prevention: Our films can also be used to prevent contamination of the process fluid by the pump diaphragm material. This is particularly important in applications where the process fluid is sensitive to contamination, such as in pharmaceutical or food processing industries.
Improved Efficiency: Our films can help to reduce friction and wear in pump diaphragms, which can improve the overall efficiency of the pump. This can result in lower energy consumption and reduced operating costs.

How are VERSIV^™ films used to improve pump diaphragm performance?

Our films can reduce the amount of wear and tear on the diaphragm, leading to longer service life and fewer maintenance requirements. The films also tend to have a smoother surface than other diaphragm materials, helping to reduce friction and improve the overall efficiency of the pump.
Additionally, our films can be more chemically resistant than other materials used for pump diaphragms. This can be particularly important in applications where the pumped fluids are corrosive or reactive with other materials. In these cases, our films can help to prevent damage to the diaphragm and extend its lifespan.
Overall, VERSIV™ films can be a good choice for pump diaphragms in applications where chemical resistance, temperature tolerance, and durability are critical factors. However, it's important to keep in mind that the specific requirements of each application vary, and the choice of diaphragm material should be based on a thorough evaluation of operating conditions and performance needs.

What role does VERSIV^™ film provide for pump diaphragms?

In industrial and manufacturing environments all over the world, our film solutions for pumps and diaphragms are contributing to smooth, leak-free, accurate, reliable, and safe pumping. From chemical and pharmaceutical to food and beverage, we are helping to enhance performance and sustainability.
Pump diaphragms are a key component in positive displacement pumps, which are used to transfer fluids in a wide range of industrial applications. The role of VERSIV™ films in pump diaphragms is to provide a flexible and durable barrier between the fluid being pumped and the mechanical components of the pump. This barrier separates the fluid from the pump's moving parts and prevents contamination, leaks, and damage to the pump.
VERSIV™ PTFE (Polytetrafluoroethylene) films are commonly used as the material for pump diaphragms because of their excellent chemical resistance, low friction, high temperature resistance, and durability. Other materials, such as elastomers or thermoplastics, can also be used for pump diaphragms depending on the application requirements.
In operation, the pump diaphragm flexes back and forth, creating a vacuum on one side and pressure on the other, which causes fluid to be drawn into and expelled from the pump. The flexibility and durability of the film material are critical to the performance of the pump, as they allow the diaphragm to flex repeatedly without rupturing or wearing out.

What are VERSIV^™ Pump Diaphragm films made of?

Our range of different film and laminate constructions are made from premium high molecular weight fluoropolymer resins. Our specialized surface treatments and proprietary
process is used to impart high flex life, low permeability, high smoothness, and a low coefficient of friction.
