High-Pressure Jet Grouting Pump for RJP/MJS Deep Foundation
JNSG series high-pressure grouting pump is specially designed for RJP (High-pressure Jet Grouting Method) and MJS (Multi-directional High-pressure Jet Grouting Method) applications. These methods impose extremely high requirements for pressure stability, precise control, and equipment reliability. Therefore, this high-pressure grouting pump features multiple integrated intelligent control and protection systems to ensure efficient, safe, and trouble-free operation even in complex working conditions.
- Integrated enclosure housing structure effectively protects the equipment from harsh weather conditions, while also facilitating disassembly, maintenance, and lifting.
- Flexible variable-frequency motor configuration with optional 132 kW/185 kW/90 kW available. With integrated flow meters and pressure sensors to provide real-time feedback on rotation speed, slurry density, flow rate, and pressure, enabling precise adjustment and stable output of construction parameters.
- Equipped with comprehensive protection systems, such as ultra-high-pressure automatic shutdown, automatic water-reduction cooling system, and forced plunger lubrication system, providing all-round equipment protection, extending core component service life, and reducing unexpected downtime.
