Criteria required designing your right Seals:

The right seal for your required application will always depend on the application parameters and the information collected from the operating conditions of the hydraulic cylinders. Below are the most common application considerations are required prior to selecting any seals...

• Seal Application Type: Firstly, It’s important to know the application of seals either of the following functions PISTON, ROD, ROTARY, RECIPROCATING, OSCILLATING, SINGLE ACTING, DOUBLE ACTING, HELICAL, FACE/FLANGE, STATIC AND DYNAMIC.
• Temperature range: The Minimum Maximum and normal operating temperature range of fluid and cylinder assembly are important on seal selection.
• Fluid pressure range: Testing and operating range of the fluid system pressure, including the severity and frequency of the system pressure peaks.
• Cycle time / Stroke speed: The velocity of the piston rod’s stroke or average cycle time per day will influence the seal’s lifetime.
• Fluid Media: The type fluid media and the viscosity are important for seal efficiency and effectiveness.
• Equipment Dimensional specifications: Seal groove dimensions, Rod / bore
  dimensions, gaps, surface roughness, cylinder’s overall length and stroke length will determine the right seal with the right profile.
• Other applications: Operating conditions includes Cylinder installation,
  environmental factors and exposure to harsh conditions are directly impact the life of seals.
• Customer Proposal: In terms of replacing your seals, Type of equipment, Size and type of existing seals and materials, present problems would be helpful to redesign.

Bullet points of SPRING ENERGIZED SEALS

Spring energized seals designed to provide durable and reliable sealing solutions in critical applications and under extreme operating conditions in different industries, where standard elastomer-based and polyurethane-based seals will not meet the operating limits, equipment parameters, or environmental conditions of your application.

High-performance fluoroplastic compounds and engineered plastics such as PTFE and PEEK virgin or filled versions are naturally not elastic to provide better sealing / cushioning effect. But they are rigid with outstanding physical and technical characteristics.

The function of the spring is to energize the sealing lip by mechanical tension even before the system pressure is applied, providing good low pressure sealing capability. When system pressure is applied, the spring action is intensified. This increases the sealing force on the seal lips, improving the sealing efficiency.
