Versiv PTFE diagraphm: Ultraflex

Used in the most demanding high-pressure applications, Versiv Ultraflex is an unmatched PTFE solution for the highest flex life requirements and permeation resistance.
Ultraflex is a Versiv Multimaterial Composite made from premium high molecular weight fluoropolymer resins, via specialised surface treatments and our proprietary process. It has all the benefits of regular PTFE composites, plus enhanced flex resistance, especially for high-pressure requirements.
Roll of Versiv Ultraflex

Main benefits of Versiv Ultraflex for pump diaphragms:

High chemical resistance:

‍PTFE composites highly resistant to chemicals, acids, and solvents. This makes them ideal for use in pumps that handle aggressive chemicals or corrosive materials.
It is also resistant to hydrolysis, making it suitable for use in humid environments.

High-temperature resistance:

Versiv Ultraflex is non-flammable/ fire resistan and has excellent high-temperature resistance. It is thermally stable from -200°C to 260°C (-328°F to 500°F) without degradation, making it suitable for use in pumps that handle hot fluids.

Flexibility and Durability:

Versiv Ultraflex is thermally weldable and has superior flexibility, allowing for diaphragms that are thin and durable. It is also resistant to tearing and abrasion, which helps prolong their lifespan.

Reduced permeation:

Reducing permeation is about equipment reliability.
Versiv Ultraflex allows for both the protection of equipment and environment, and the reduction of leakage and media loss.

Smoother flow:

PTFE materials have a very low coefficient of friction, which means they do not stick to other materials easily.
This leads to time, materials and energy savings through the low friction & easy release properties. It also makes them ideal for use in pumps that handle viscous or sticky fluids.

Ultraflex pump diaphragm materials: 70% more cycles, 30% less permeation

Manufacturers choose diaphragm pumps across a breadth of industries because they contain few moving parts and components that can come in to direct contact with the product. Every effort must be made to ensure the media running through the pump is entirely free from external contamination. Any failure can mean a drop in production, losing the company valuable time and considerable revenue. Defects can also impact on safety.

Versiv Ultraflex is used as the flexible barrier that separates the liquid or gas being pumped from the rest of the pump components.

Pump problems solved with Versiv Ultraflex:

  • Premature failure due to PTFE rupture has been solved by the exceptional flex-life performance.
  • Diaphragm delamination caused by bad etching, unsteady bonding quality to rubber and media permeation that destroys bonding/rubber has been overcome by higher quality sodium ammonia etching on a Flex Barrier constructed from a low permeation rate laminate with a barrier enhancement process. The result is excellent bonding with a significantly reduced stretch void index and a 30% reduction in permeation.
  • Contamination attributable to a diaphragm’s rough surface hasbeen eliminated by the smooth inert surface of the barrier.
  • For deep drawing manufacturing issues, where the problem’s root cause is stiff and heterogeneous material, the high quality and flexibility of these barrier films removes cause for concern.

Versiv food compliant Release Solutions are effective productivity aids that consistently deliver quality food from production to grilling, baking, and vacuum drying processes. Because of their non-stick processing surface, our PTFE coated processing belts and PTFE release sheets deliver a clean, consistent and long-lasting release surface, resolving issues with cleaning, sticking and contamination of food and dried ingredients. With fewer unplanned stoppages for clean-downs associated with sticking issues - consistent production, improved productivity and cost effectiveness is achievable.
