LGP250/450-250D High pressure jet grouting pump stands out as a sophisticated piece of machinery, specifically engineered as a horizontal three cylinder single action reciprocating pump. Our company, drawing inspiration from the cutting edge structural designs of foreign plunger pumps, has meticulously crafted this pump to meet the highest industry standards.



This high pressure triplex jet grout pump is a well - integrated system, comprising several key components. At its core is the power end, which is a robust 260HP diesel engine. This QSF6.7-260C Cummins serves as the heart of the jet grout pump, providing the necessary power to drive the entire system. Connected to the power end is a clutch, which allows for smooth engagement and disengagement of power transmission.



The gear box, manufactured by the renowned Eaton FAST, is another crucial part. It features four gears and offers the advantage of being continuously variable according to specific operational requirements. This flexibility enables the jet grout pump to adapt to different working conditions, ensuring optimal performance. In addition to the gear box, a universal joint coupling is incorporated into the design, facilitating efficient power transfer between the various components.



One of the standout features of the LGP250/450-250D is its high pressure pump section. Unlike traditional domestic products that often utilize needle roller transmission, which is susceptible to damage, this high pressure grout pump adopts a tile type transmission. This innovative design change brings about significant benefits. While there is normal wear and tear between the tiles and the shaft, it does not lead to sudden, catastrophic failures that can halt a project. As a result, the working life of the pump's power end is greatly extended, reducing maintenance costs and downtime.



From a logistical perspective, the LGP250/450-250D diesel  driven high pressure jet grouting pump offers great convenience. It can be easily placed inside a 20ft container, which simplifies transportation. This makes it possible to quickly deploy the pump to different project sites, whether they are located in remote areas or urban centers.

The applications of the LGP250/450-250D high pressure diesel driven  jet grouting pump are diverse and far reaching. In the field of construction, it plays a vital role in strengthening weak foundations. Whether it's for new buildings, highways, high - speed railways, or underground railways, this pump provides the high pressure power needed to ensure the stability and durability of these structures. For old buildings suffering from uneven settlement, the high pressure jet injection pump can be used for treatment, helping to restore their structural integrity.



In geotechnical engineering, it is used for creating deep prevention curtains and soil retaining cofferdams. These structures are essential for preventing soil erosion and ensuring the safety of adjacent areas during construction projects. In the mining industry, the pump is used for mine leakage prevention, well barrel protection arms, and slope anchoring, contributing to the safe and efficient extraction of minerals.



In reservoir dams and underground construction projects, the pump's capabilities are also highly valued. It can be used for high pressure water harvesting, which assists in rock breaking and coal falling, making the mining process more efficient. Additionally, it provides hydraulic props for underground hydraulic supply, ensuring the stability of underground workings. Anchoring operations, such as the use of hydraulic expansion metal anchor rods, also rely on the pump to pump high - pressure water.



Moreover, the high pressure jet grouting system has applications in the maintenance of large underground pipelines. It can be used for dredging and cleaning, ensuring the smooth flow of fluids through these pipelines. In the field of rock and soil excavation, it can create perforations using high pressure water jets, making it easier to break through tough materials.
