LGP120/30PI-E grout pump for foundation grout is driven by electric motor, which is the power for hydraulic system. The symmetrically designed piston pump realizes the continuity of suction and discharge through reciprocating movement of hydraulic cylinder. At the same time, the closed cavity can generate high pres sure, so that the mud can be injected with a certain pressure to complete the shotcrete action.

1. Double cylinders piston pump to ensure the continuous slurry flowing (small pulse) and not easily leaking compared with the double acting piston pump.

2. Hydraulic system is equipped with oil temperature protection system.

3. Both hydraulic air and water cooler.

4. Grouting pressure and displace ment can be adjusted steplessly.

5. PLC and HMI control.

6. Solid state relay.
