high pressure jet grouting pump

Key Features of a Jet Grouting Triplex Pump:
High-Pressure Delivery: Jet grouting requires the injection of grout at very high pressures to effectively erode and mix the in-situ soil. A triplex pump is capable of delivering the necessary pressure, often in the range of 20 to 50 MPa (or higher, depending on the specific application).
Consistent Flow Rate: The three cylinders of the triplex pump work in a coordinated manner to ensure a consistent flow rate of grout, which is crucial for maintaining the quality and uniformity of the grout columns.
Durability and Reliability: Jet grouting pumps are subjected to harsh operating conditions, including abrasive grout mixtures and high pressures. A triplex pump is designed to withstand these conditions, with robust construction and high-quality components to ensure long-term reliability.
Adjustable Parameters: The pump should allow for adjustments in pressure, flow rate, and other parameters to accommodate different soil conditions and project requirements.
Efficiency and Performance: A well-designed triplex pump will offer high efficiency and performance, minimizing energy consumption and maximizing the effectiveness of the jet grouting process.

The Jet Grouting Pump is a critical component of the jet grouting system, responsible for delivering the grout under high pressure. The pump must be capable of generating pressures in the range of 20-50 MPa to ensure effective soil erosion and grout penetration. The pump should allow for precise control of the grout flow rate to match the specific requirements of the project (e.g., soil type, desired column diameter).

Diesel jet grouting pump uses diesel engine as power source, which enables the equipment to work normally in remote areas without electricity supply or unstable electricity supply. It can generate enough pressure to achieve efficient jet grouting operation, usually reaching pressure level of tens or even hundreds of MPa, ensuring that the grout can penetrate deep into the cracks of the formation. It is suitable for various types of soil conditions, whether it is loose sand or hard rock, and the construction parameters can be adjusted according to the actual situation. Due to the changeable and harsh use environment, diesel jet grouting pumps are generally made of strong and durable materials and are strictly tested to ensure their reliability and long life.

Due to the standard container design, this type of container type grouting pump can be easily transported by road, rail or sea to any place where it is needed, and can be put into work quickly after arriving at the site. It can handle various types of grouting materials, such as cement slurry, chemical slurry, etc., and is suitable for different engineering needs, including foundation reinforcement, waterproofing, crack filling, etc.

Jet grout pump for self drilling injection is a grouting equipment specifically designed for self drilling jet grouting technology. This technology combines drilling and grouting processes, using a self drilling grouting pipe (usually with a nozzle) to drill holes in rock and soil, while injecting high-pressure grout into the hole to achieve grouting reinforcement or waterproofing purposes.

The working pressure of 600-800 bar enables the High press jet grouting pump to penetrate deeper rock and soil layers, achieving effective grouting reinforcement. According to engineering needs, the flow rate of the grouting pump can be adjusted to meet the requirements of different grouting processes. The design of modern high-pressure jet grouting pumps emphasizes the compactness of the structure, making it easy to transport and install. The High press jet grouting pump 600-800 bar adopts an advanced control system, making the operation of the grouting pump more convenient and efficient.

Jet grouting pump, also known as grouting machine or grouting pump, is a device used to inject various grouts such as cement slurry, water glass, clay slurry, polyurethane, accelerators, etc. into media such as foundations, rocks, walls, etc. under high pressure. A 100bar jet grouting pump refers to a grouting pump whose working pressure can reach 100 bar (MPa). This type of pump is usually used in scenarios that require high grouting pressure, such as deep foundation treatment, tunnel reinforcement, slope stability, and other engineering projects.

Jet grouting triple pump refers to a triple pump dedicated to the jet grouting process, which usually consists of three independent pumps, namely a water pump, compressor, and concrete pump.

Jet grouting pump is a kind of machine equipment commonly used in the fields of soil treatment, concrete reinforcement and geological exploration. It processes the soil by spraying a mixture of liquid and solid materials at high speed to form a solid formation. Jet grouting pump is generally composed of pump body, mixing head, measuring instruments, control equipment, etc., and parameters such as flow, pressure, and ratio can be adjusted freely according to engineering needs to meet different reinforcement needs.

There are several advantages to installing a jet grouting pump in a container. First, it provides protection and security for the pump during transportation and storage. Second, it increases the safety of the operation by containing the pumping process within an enclosed area. This helps prevent accidents and minimizes the impact of any spills or leaks. Third, the jet grouting pump in container is more versatile as it can be easily transported to different job sites and customized for specific projects. It can also be equipped with additional accessories and components, such as generators and storage tanks, to provide a complete and self-contained pumping system.

The diesel jet grouting pump in container is a powerful and versatile tool for ground improvement projects. Powered by a diesel engine with a 10-speed gearbox and pneumatic clutch, it is designed for high pressure grout injection and jet grouting systems. It is particularly suitable for complex accumulation of water or casing that requires targeted treatment, making it an excellent choice for bracing, water control, soil stabilization and other geotechnical challenges.

High pressure jet grouting pump can also be used in the core drilling of geologic engineering as a substitution of slime pump. 

From years of experience, LEC is the leading factory of China new jet grout pump manufacturer, for more information about grouting equipment, please email us.

We have exported a set of pneumatic high-pressure grouting pump to Malaysia last year, the hydraulic grout pump is working well at the work site.

During the drilling rig jet grouting pump construction of the reinforcement process, due to the limitations of the reinforcement process, in some soil conditions will produce slurry and pulp phenomenon, so that the incorporation of cement slurry is not effectively retained in the need to strengthen the area
