Jet grout high pressure pump
The jet grout high pressure pump is driven by an electric motor, providing power to the hydraulic system. The symmetrically designed piston pump achieves continuous suction and discharge through the reciprocating motion of the hydraulic cylinder. Simultaneously, the enclosed cavity generates high pressure, allowing grout to be injected at a specific pressure. The jet grout high pressure pump is mainly used in surface/underground construction, such as highways, railways, water conservancy and hydropower, buildings, and mines.

Jet grout high pressure pump Features:
1. Dual-cylinder piston pump design ensures continuous grout flow (small pulses), and is less prone to leakage compared to double-acting piston pumps.
2. The hydraulic system is equipped with an oil temperature protection device.
3. The hydraulic system uses both air and water coolers.
4. Grouting pressure and discharge rate are infinitely adjustable.
5. PLC and HMI control.
6. Solid-state relays.
