Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
Rotary Spring Energized Seals with Flange
High - Performance Sealing Solution for Rotating Equipment in Harsh Conditions
These are rotary spring - energized seals with flanges, manufactured using imported PTFE. PTFE boasts exceptional chemical stability, outstanding resistance to high and low temperatures (ranging from approximately -200℃ to 260℃), and an extremely low friction coefficient. As a result, these seals can function effectively in various harsh working conditions, such as environments with highly corrosive media. They are widely applied in the sealing systems of rotating equipment in fields like hydraulics, pneumatics, and chemical engineering, efficiently preventing fluid leakage.

1. Product Advantages
Crafted with imported PTFE, Forever Seals’ rotary spring-energized seals with flanges deliver unmatched performance. They feature exceptional chemical stability, resisting corrosion from harsh media like acids, alkalis, and solvents—ideal for demanding industrial environments. With a wide temperature tolerance range (-200℃ to 260℃), they maintain sealing integrity in extreme hot or cold conditions. Additionally, the low friction coefficient of PTFE minimizes wear on rotating components, extending the seal’s service life and reducing equipment maintenance costs. The integrated flange design also ensures easy and precise installation, saving time during assembly.
2. Working Principle
This seal operates on a spring-energized mechanism. The imported PTFE sealing lip, paired with a high-elasticity internal spring, creates consistent contact pressure against the rotating shaft or housing. When the equipment starts running, the spring compensates for any slight wear on the PTFE lip or dimensional deviations, ensuring a tight seal at all times. The PTFE material’s low friction allows smooth rotation without compromising sealing efficiency, while the flange acts as a stable base to fix the seal in place, preventing displacement during operation.
3. Product Details
Material: 100% imported PTFE (food-grade optional for hygiene-sensitive industries) + high-quality stainless steel spring (resistant to rust and fatigue).
Flange Design: Precision-machined flange with standardized mounting holes, compatible with most rotating equipment in hydraulics, pneumatics, and chemical sectors.
Sealing Lip: Polished PTFE lip with optimized geometry to enhance contact with the rotating surface, reducing leakage risk to near-zero.
Dimensions: Customizable sizes available (from 10mm to 500mm inner diameter) to meet specific equipment requirements; strict dimensional tolerance control (±0.02mm) ensures perfect fit.
4. Application Range
Forever Seals’ rotary spring-energized seals with flanges are widely used across industries, including:
Hydraulics & Pneumatics: Rotating shafts in hydraulic cylinders, pneumatic actuators, and gear pumps.
Chemical Engineering: Sealing for agitators, mixers, and centrifuges handling corrosive fluids (e.g., sulfuric acid, sodium hydroxide).
Food & Pharmaceutical: Rotating components in food processing machinery (e.g., beverage bottling lines) and pharmaceutical reactors (compliant with FDA standards when using food-grade PTFE).
Aerospace & Automotive: High-temperature rotating parts in engine systems or fuel delivery components.
5. FAQ
Q1: Can this seal be used with high-pressure rotating equipment?
A1: Yes. The spring-energized structure and robust PTFE material enable the seal to withstand pressures up to 30MPa, making it suitable for high-pressure hydraulic/pneumatic applications.
Q2: How often should the seal be replaced?
A2: Under normal operating conditions (proper installation, compatible media), the seal can last 2,000–5,000 operating hours. Replacement intervals may vary based on harshness of the environment (e.g., high temperature or corrosive media may shorten lifespan).
Q3: Is custom sizing available for non-standard equipment?
A3: Absolutely. Forever Seals offers custom design and manufacturing services—simply provide your equipment’s dimensional requirements, and our engineering team will develop a tailored solution.
