PU INJECTION PACKERS

Product Details:

 91 000 74051 The precisely designed Injection Packer is basically a replaceable tool which is required for injecting chemical based grouting materials like epoxy and polyurethane resins into fractures appeared on concrete structures. It is used as an indispensable part of advanced grouting equipment under high pressure for inserting water sealing grouting elements into the cracked concrete structure. Convenient to use, install and remove, this grouting injection medium can be accessed in different configurations to suit the exact grouting based repairing needs of construction industry. It consists of components like inflatable black colored rubber made section with exceptional toughness level, zinc or nickel treated grease nipple and packer core.
Uses and Applications: This Injection Packer is required for repairing structural damage of tunnels, subways, basement and underground passage.Its application can also be noticed during pipelines maintenance and concrete structure leakage repairing work.It is also used to safeguard wall corners, columns, beams, different types of concrete structures and through wall pipe water against water.FeaturesStandard grade aluminum, steel and brass have been used to design its highly durable ferrule part.It is fitted in the drill hole of a specific building.It adopts inclined injection insertion method.It does not leave any stain mark on injected surface.

Product Details:

 91 000 74051 Injection packers are ports or fittings inserted into drilled holes in concrete, masonry or other structural elements so that injection materials (epoxy, polyurethane, acrylate gels etc.) can be pumped into cracks, voids, or joints. They act as sealed access points so the injection grout or resin enters the structure under pressure without escaping.
Important Specifications / What to ChooseDiameter of packer: depends on how much flow you need and what crack size / pressure. Common diameters ~ 6 mm, 10 mm, 13 mm, 16 mm etc. Length / Shaft length: Longer packers help in weak or deteriorated concrete so they grip well in the hole without blowing out. Short ones are fine for shallow cracks. Valve type / fitting type: Zerk type vs Button-Head vs Anti-Return Valve. Anti-return valves help prevent backflow and ease multiple injections. Button-head or flat-head help with fast hose connection. Material strength & corrosion resistance: Steel gives high strength and good pressure resistance; aluminum/brass cheaper; plastic lighter. Choose depending on environment and pressure.
Q. What diameter should I choose? Depends on volume / flow and crack/void size; 10-13 mm common for concrete crack injection.Q. Can these packers be reused? Some metal packers may be reusable; plastic ones often single use.Q. What injection materials can be used? Epoxy, PU, acrylate, silicate etc. Check compatibility with valve and packer material.Q. How to finish after injection? Pull out or break off the packer stem if needed, seal hole with patch repair mortar.
