China's leading manufacturer of advanced high-pressure jet grouting technology
LaiZhou SanYi Engineering Machinery Co., Ltd., located along the beautiful and fertile coast of Bohai Sea (LaiZhou Bay), enjoys a superior geographical setting—just one kilometer from the sea. We are a specialized manufacturer dedicated to the research, development, and production of various high- and low-pressure piston pumps as well as advanced high-pressure jet grouting equipment. Backed by our cutting-edge technology, state-of-the-art machining facilities, and meticulous quality-control processes, we ensure top-notch product reliability. Our high-pressure grouting pumps include both high-pressure clear-water pumps and high-pressure slurry pumps, widely used in foundational engineering projects, high-pressure waterjet cleaning and derusting applications, and industries such as petrochemicals, hydropower, and water resources management.
The low-pressure plunger pump is a three-cylinder design, capable of handling water, mud, cement slurry, cement mortar, and various mineral slurries. It is widely used in geological drilling, hydrological well drilling, oil drilling circulation systems, foundation grouting projects, construction applications for transporting cement slurry and cement mortar, as well as tailings transportation in mining operations.
High-pressure jet grouting equipment includes high-pressure slurry pumps, integrated drilling and grouting rotary jetting rigs, and high-jet trolleys, among other components. It is widely used in various hydraulic, hydroelectric, and civil engineering projects aimed at seepage control and foundation reinforcement.
The company integrates research, production, and construction, enabling it to provide a comprehensive one-stop service—from design and manufacturing to installation—tailored to meet customer needs.
Undertaking high-pressure jet grouting construction for large-diameter piles (3–7 meters). Completing preliminary engineering tests on behalf of the client.
Our company’s mud pumps, high-pressure jetting rigs, and other equipment have been used in the construction of projects such as the Hong Kong-Zhuhai-Macao Bridge, the Zhangjinggao Yangtze River Bridge, and the reinforcement work for the third runway at Hong Kong’s new airport.
