Pillow Type Packers with Bypass (0,5 - 1 bar)

Description & features

Plugline Pillow Type Packers with Bypass are essential, high-flexibility tools engineered for sewer and pipeline maintenance, particularly within trenchless rehabilitation (CIPP) projects. These inflatable packers are designed with an integrated bypass, allowing for flow management or the introduction of repair materials while maintaining a secure, watertight seal. Their soft, adaptable structure makes them the preferred choice for navigating restricted access points and irregular pipe conditions.

Key Features

• Integrated Bypass Port: Features a built-in bypass that allows for continuous flow diversion or the controlled injection of resins and grouts during rehabilitation.
• NR construction: size range 200×300 — 1500×2000 mm, working pressure 0,5 / 1,0 bar, contact length 1000 — 3400 mm, operating temperature −40 to 70 °C, Quick Coupling / Schrader air connection.
• Highly Adaptable Inflatable Design: The soft-pillow configuration allows the packer to mold perfectly to the inner pipe surface, ensuring a tight seal even in aged or slightly irregular pipelines.
• Premium Chemical-Resistant Fabrics: Manufactured from high-strength, durable materials specifically chosen to withstand the harsh chemicals and abrasive environments found in industrial and waste systems.
• Rapid Deployment & Retrieval: Engineered for quick inflation and deflation, allowing for easy handling through standard manholes and minimal operational downtime.
• Multi-Size Versatility: Available in a wide range of adjustable sizes to accommodate diverse pipe diameters with a single unit.

Advantages

• Enhanced Operational Efficiency: The bypass capability allows maintenance and repairs to proceed without requiring a complete system shutdown or total flow bypass.
• Trenchless Repair Excellence: Ideal for localized patching and lining, providing a "no-dig" solution that protects surrounding infrastructure and reduces labor costs.
• Superior Maneuverability: Their flexible, collapsible nature allows them to be inserted into pipes where rigid, cylindrical packers cannot fit.
• Cost-Effective & Reusable: Designed for long-term durability and repeated use, providing a high return on investment for municipal and industrial contractors.
• Maximum Site Safety: Provides a secure physical barrier that prevents leaks and minimizes contamination risks during sensitive pressure testing or repair work.

Application Areas

• Trenchless Pipeline Rehabilitation: The go-to tool for pipe lining and sectional patching projects, enabling high-quality repairs without excavation.
• Municipal Sewer & Drain Maintenance: Used to isolate specific pipeline sections for systematic cleaning, inspection, or sealing.
• Hydrostatic Pressure Testing: Sealing one or both ends of a pipe section to test for leaks under pressure.
• Emergency Infrastructure Repairs: Provides a rapid-response solution to seal damaged pipes and prevent environmental leaks during urgent repair scenarios.
• Urban Infrastructure Projects: Highly effective for maintaining complex city drainage networks where access is limited to small gullies or manholes.

Plugline Pillow Type Packers with Bypass offer the perfect combination of professional-grade sealing and flow flexibility, ensuring that even the most complex pipeline rehabilitation tasks are completed with precision and efficiency.
