Dam Foundations Vertical Injection Grouting Pump for Building and Bridge Repair
The HWGM90/100PLD-E Dam foundations vertical injection grouting pump is a high-performance grouting device specifically developed for projects such as foundation stabilisation, curtain grouting, crack repair and structural reinforcement. Combining high flow rate, high pressure and exceptional wear resistance, this machine is capable of meeting a wide range of grouting requirements, from filling minute fissures to filling large-volume cavities. It is widely used in the treatment of foundations for water conservancy and hydroelectric dams, the reinforcement of subsiding buildings, the replacement of bridge bearings and crack repair, and the sealing of leaks in tunnel linings.

The dam foundations vertical injection grouting pump utilises advanced hydraulic transmission technology, combined with a large-diameter, long-stroke plunger pump head, to ensure stable pressure and uniform flow rates during the grouting process, thereby effectively guaranteeing the quality and efficiency of grouting projects.

Dam foundations vertical injection grouting pump Key Advantages:
Hydraulically driven, smooth operation: Equipped with a 15 kW power unit, the hydraulic transmission ensures a pulsation-free grouting process, effectively enhancing grout compaction.
Flexible parameter adjustment: Flow rate (0–90 L/min) and pressure (0–100 bar) are both infinitely adjustable, adapting to grouting volume requirements across varying geological conditions.
High wear resistance and excellent passage capacity: Permits a water-to-cement ratio of ≥0.5:1 and a maximum particle size of 8 mm; capable of conveying cement slurry, cement mortar and micro-cement slurry without clogging.
Robust and durable construction: Features a large-diameter 85 mm plunger and a 190 mm long-stroke design, combined with a skid-mounted chassis for convenient on-site hoisting and stable, reliable operation.

This pump is a highly efficient and reliable grouting device for dam foundation reinforcement and bridge maintenance projects.
