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.
