LGP1200/1200/2×75/100PL-E Automatic grout pump station is an all-in-one automated grouting system that integrates a high-speed vortex mixer, a circulation agitator pump, and a hydraulic plunger grouting pump on a single skid-mounted platform. Primarily engineered for producing cement-based slurry and bentonite grout, it serves a wide range of above-ground and underground construction projects — including highways, railways, hydropower dams, building foundations, and mining operations.



At the heart of the system lies a high-velocity eddy current mixer that blends water and dry cement (or bentonite powder) rapidly and uniformly, delivering a consistent slurry in seconds. The mixed grout is then continuously circulated through the agitator pump, preventing any settlement or separation before being fed directly into the grouting pump for injection. This closed-loop design guarantees uninterrupted mixing and pumping — no batch downtime, no manual intervention.



The entire unit is governed by a PLC-based control panel with a built-in material distributor and S-type load cell, allowing operators to freely program water-to-cement ratios, additive dosages, and material formulas. Simply input your mix design, and the station automatically meters every component — water, cement, and chemicals — with precision. This fully automated batching process dramatically cuts labor costs and boosts on-site productivity compared to traditional manual grouting setups.

1. Civil Engineering: Dam grouting, tunnel & subway construction, curtain grouting, cable trench filling.
2. Geotechnical: Soil nailing walls, slope support, anchor & tieback grouting, micropiles.
3. Mining: Roadway reinforcement, backfill grouting, and waterproof grouting.
4. Building & Infrastructure: Foundation reinforcement, bridge repair, building underpinning.
5. Hydropower: Underwater foundation grouting, offshore platform stabilization.
6. TBM / Pipe Jacking: Acts as the grouting plant for tunnel boring machines and pipe jacking operations.
