Inflatable Seal Design

Discover our innovative approach to seal design, ensuring superior performance and reliability for your specific application needs.

Our Design Process

Creating the perfect inflatable seal involves a meticulous process that considers every aspect of your application. Our expert team guides you through each step to ensure optimal performance and longevity.

1

Situation Analysis

We begin with a comprehensive evaluation of your specific requirements, including operating conditions, environmental factors, and performance expectations. This foundational analysis informs all subsequent design decisions.

2

Material Selection

Based on your application's demands, we choose from a wide range of elastomers with varying properties to ensure chemical compatibility, temperature resistance, and mechanical durability for optimal seal performance.

3

Profile Design

We select the ideal seal profile configuration to match your application's requirements, considering factors such as inflation pressure, sealing force, and space constraints to ensure effective sealing.

4

Expansion Direction

Determining the optimal direction of seal expansion is crucial for effective sealing. We carefully analyze how the seal will interact with surrounding components to ensure proper inflation and sealing action.

5

Connector Integration

We integrate appropriate air connectors based on your operational requirements, considering factors such as pressure levels, space constraints, and ease of maintenance for reliable inflation and deflation.

6

Prototyping & Testing

Before final production, we create and test prototypes to verify performance under simulated operating conditions, making refinements as needed to ensure the seal meets or exceeds your specifications.

Critical Design Considerations

Successful inflatable seal design requires careful evaluation of multiple factors that influence performance and longevity. Our approach ensures every relevant variable is accounted for.

Pressure Requirements

We analyze both the operating pressure range your seal must withstand and the inflation pressure needed for effective sealing. This critical balance determines material thickness, reinforcement needs, and overall seal design.

Media Compatibility

Exposure to chemicals, gases, or abrasive substances requires careful material selection to prevent degradation. We match elastomer properties to your specific media to ensure long-term seal integrity and performance.

Temperature Range

Extreme temperatures can significantly impact elastomer performance. We select materials specifically rated for your operating temperature range, from cryogenic applications to high-heat environments.

Duty Cycle

The frequency of inflation/deflation cycles affects seal durability. Our designs account for your specific operational patterns, incorporating reinforcement and material selections that withstand repeated flexing.

Industry Standards

Different industries have unique requirements and compliance standards. Our designs adhere to relevant regulations for sectors including food processing, pharmaceutical, aerospace, and heavy industrial applications.

Certification Requirements

When necessary, we design seals to meet specific certifications such as FDA compliance, USP Class VI, ATEX, or industry-specific standards, with complete documentation for your quality assurance needs.

Selecting the Optimal Seal Shape

The geometry of your inflatable seal significantly impacts its performance. We offer various configurations to address different sealing challenges.

Circular inflatable seal configuration for pipe connections and rotary equipment

Circular Seals

Ideal for cylindrical applications such as pipe connections, valve seals, and rotary equipment. Circular seals provide consistent sealing force around curved surfaces with uniform expansion characteristics.

Rectangular inflatable seal configuration for doors, hatches, and access panels

Rectangular Seals

Perfect for doors, hatches, and access panels where a defined rectangular sealing area is required. Our corner design ensures proper inflation and sealing even at sharp transitions.

Custom shaped inflatable seal for complex geometries and unique applications

Custom Shapes

For unique applications with complex geometries, we design and manufacture custom-shaped seals that conform precisely to your specific requirements, ensuring optimal sealing performance.

Material Selection

Choosing the right elastomer is critical for seal performance. We offer a wide range of materials to meet your specific requirements.

EPDM

Excellent resistance to weathering, ozone, and UV exposure. Ideal for outdoor applications and water sealing with temperature range from -40°C to +150°C.

NBR

Superior resistance to oils, fuels, and hydrocarbons. Perfect for applications in oil and gas, automotive, and industrial machinery from -30°C to +100°C.

Silicone

FDA-compliant for food and pharmaceutical applications. Excellent temperature range from -60°C to +230°C with outstanding flexibility at low temperatures.

FKM (Viton®)

Exceptional chemical resistance and high-temperature performance up to +275°C. Ideal for harsh chemical environments and high-temperature applications.

Expansion Direction Technology

The direction in which an inflatable seal expands is a critical design factor that directly impacts sealing effectiveness in different applications.

Strategic Expansion Design

Our engineers carefully analyze your application to determine the optimal expansion direction, considering factors such as available space, sealing surface characteristics, and required sealing force.

Axial Expansion

Expands perpendicular to the mounting surface, ideal for face sealing applications like door and hatch seals where direct pressure against a flat surface is required.

Radial Expansion

Expands outward from the center axis, perfect for sealing the inside of tubes, pipes, and cylindrical openings with consistent pressure against the inner wall.

Radial Compression

Contracts inward when inflated, ideal for external sealing of shafts and other cylindrical components where wrapping around the exterior is required.

Multi-Directional

Combines multiple expansion directions for complex applications where sealing must occur against surfaces at different orientations simultaneously.
