Today, our factory shipped a full hydraulic high-pressure cement injection grouting pump, which is an upgrade based on the GDH70 & GH90 High-Pressure Grouting Pump design. It uses a hydraulic drive (instead of pneumatic or mechanical drive) to generate high pressure for injecting cement slurry, chemical grout, or other materials into rock fissures, soil cavities, and structural cracks.
Tunnel Engineering: Face grouting, backfill grouting, and waterproofing
Mining/Coal Mining: Tunnel reinforcement, waterproofing, grouting
Water Conservancy Engineering: Dam grouting, seepage control, tunnel crack sealing
Metro/Light Rail: Segment grouting, structural crack repair
Building Engineering: Foundation treatment, crack grouting, and basement waterproofing
Bridge/Highway: Post-grouting of pile foundations, floor slab void filling
Slope/Retaining Wall: Anchor grouting, soil nailing reinforcement
Chemical Industry: Acid and alkali slurry transportation, titanium dioxide slurry
Advantages of full hydraulic design:
1. Pressure & Flow Stepless Adjustment: Adapts to different grouting requirements in real-time
2. High Reliability: The hydraulic system is more stable than pneumatic; less wear
3. Explosion-Proof Option: Equipped with an explosion-proof motor for underground/flammable environments
4. Dual-Liquid Capability: Can mix two liquids (e.g., cement + water glass) with an adjustable ratio
5. Auto Pressure Control: Auto start/stop based on set pressure; maintains pressure during holding period
6. Compact Structure: Valve group integrated design
7. Easy Maintenance: Quick disassembly, modular design
