Applications

The XQV HB-3 piston grouting pump is suitable for medium and low viscosity materials such as cement slurry and cement mortar. With a working pressure of 1.5 MPa, it is ideal for small to medium‑sized grouting operations.

Typical applications include:

Crack repair of building components and grouting of post‑cast strips
Grouting filling of bridge bearings and precast beam pipelines
Gap filling between tunnel secondary lining and surrounding rock

Note: For high‑viscosity pastes or slurries containing large aggregate particles, equipment with higher pressure may be required.
