Feature
1. Simple structure, more stable with imported parts
2. Easy-maintaining
3. Light-weight, wheel-type, easy-transporting
4. Wide range for cement and water, suitable for thick mortar
5. Wide range for cement and sand ratio, wide range for aggregate
6. Continuous grouting which avoids large instantaneous pressure fluctuation of piston pump
7. When grouting fully, pressure increases gradually, make it is easy to control and maintain pressure.
8. Could relief pressure reversely when the grouting pressure reaches the designed.
9. With remote control, could be controlled in 10 meters.
Application
