Plunger jet grouting pump working principle: Plunger reciprocating motion: The plunger reciprocates in the pump cylinder, changing the sealed volume to achieve the suction and discharge of slurry. High-pressure injection: The slurry is pressurized to more than 20MPa through a high-pressure pump and ejected at high speed through a nozzle, impacting and destroying the soil and forming a consolidated body.

The high pressure triplex pump consists of three parallel plungers or pistons, which are driven by a crankshaft to achieve reciprocating motion. The three-cylinder design can significantly reduce pressure pulsation, make fluid delivery more stable, and improve grouting efficiency.

Jet Pump Grout Systems pressurizes the grout to more than 20MPa and ejects it at high speed through the nozzle. The high-speed jet impacts and destroys the soil, and the grout mixes with the soil particles. After the mixture solidifies, it forms a cylindrical, plate-shaped or wall-shaped consolidation body to improve the foundation strength or achieve anti-seepage.
