LaiZhou SanYi Construction Machinery Co., Ltd., located on the beautiful and fertile shores of the Bohai Sea (LaiZhou Bay), enjoys a superior geographical location—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 high-pressure jet grouting equipment.

Our factory boasts advanced technological expertise, state-of-the-art processing equipment, and comprehensive testing procedures, ensuring top-notch product quality. High-pressure grouting pumps are available in two types: high-pressure clear water pumps and high-pressure slurry pumps, widely used in applications such as foundation treatment projects, high-pressure water jet cleaning for rust removal, as well as in the petrochemical, hydraulic power, and water conservancy sectors. On the other hand, low-pressure plunger pumps are three-cylinder models capable of handling a variety of fluids—including water, mud, cement slurry, cement mortar, and diverse mineral slurries. These pumps find extensive use in geological drilling, hydrological well drilling, petroleum drilling circulation systems, foundational grouting projects, construction engineering for transporting cement slurry and mortar, and even in mining operations involving tailings transportation.

High-pressure jet grouting equipment includes high-pressure grout 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 & industrial construction projects for foundation seepage control and 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.
