220V Portable Multi-function Grouting Steel Machine For Concrete Repair Crack good mechanical properties

  ⭐【11000PSI Ultra-high Stable Pressure Output】Adopting 1100W high-power core configuration, this grouting machine delivers up to 11000PSI max working pressure and 7500PSI stable restart pressure. It supports continuous constant pressure operation, effectively pushing grout deep into tiny structural micro gaps, capillary holes and invisible cracks that ordinary machines cannot fill, achieving thorough internal sealing and leakage prevention. ⭐【One-way Valve Anti-backflow Water Stop Needle】Matched with professional steel and plastic injection packers, the one-way valve design at the needle head perfectly blocks high-pressure slurry backflow. Firmly fixed in building drilling holes, it stably connects the grouting machine and building components to ensure precise and loss-free high-pressure grouting, greatly improving plugging accuracy and construction efficiency. ⭐【4500-10000PSI Galvanized Butter Head】Comes with premium straight galvanized steel butter head coupler, featuring strong pressure resistance and corrosion resistance. It tightly connects the host device and water stop needle, adapting to 4500-10000PSI wide pressure range. No slurry leakage or pressure loss during high-intensity operation, ensuring stable and smooth grouting progress. ⭐【Multi-level Super Safety Pressure Resistance】Built with upgraded high-pressure resistant accessories, the pipeline safety bearing capacity reaches 14000PSI and the switch valve withstands up to 18000PSI. The large safety pressure margin effectively avoids pipe burst and equipment damage under long-term high-pressure work, realizing zero-risk engineering construction. 【Features】1. 11000PSI ultra-high pressure, deep micro-gap filling & plugging2.
