Project Introduction

Laos gold mine procurement of XS250-480B type split-case pump diesel engine unit.

In a certain open-pit gold mine in Laos, rainfall is concentrated during the rainy season, leading to water accumulation in the mining pits that severely hinders mining operations. Additionally, the mine’s power supply is unreliable, making electric pumps unable to meet emergency drainage requirements. At the same time, the water in the pits contains high levels of sediment, imposing stringent demands on the stability, wear resistance, and battery‑free operation of drainage equipment. To address the challenges of flood control and drainage during the rainy season, the mine management conducted extensive comparisons and ultimately procured… XS250-480B Diesel Engine Mid-Opening Pump Assembly , used for dewatering operations in mining areas.


This pump unit is independently driven by a diesel engine, eliminating the need for an external power grid and completely mitigating the risk of drainage stagnation caused by power outages in mining areas, making it well-suited to complex, off‑grid power conditions. Equipped with a double‑suction, mid‑open design, it delivers high‑flow drainage performance, enabling rapid removal of extensive water accumulation across large mining sites. Its wetted components undergo wear‑resistant treatment, effectively resisting erosion from sand and sediment, thus adapting to the challenging, abrasive nature of mine water. Meanwhile, the horizontal mid‑open configuration streamlines maintenance, allowing component servicing without dismantling piping, which is particularly advantageous in overseas mining operations where maintenance resources are limited. The unit can be mounted on a trailer for mobile deployment, facilitating flexible relocation to multiple work locations and covering numerous drainage zones within the mine, offering exceptional practicality.
Once the equipment is installed and put into operation, it can be rapidly commissioned during the flood season to achieve efficient drainage, effectively addressing the risk of waterlogging in open-pit mining pits and ensuring the continuous and stable conduct of mining operations. The application of this overseas project has thoroughly validated… Mid‑open pump for the XS250‑480B diesel engine This pump is designed to withstand the harsh operating conditions of mining sites—remote, unpowered environments with muddy, sediment-laden media—making it an excellent solution for emergency drainage during the rainy season at open-pit mines. It also underscores the reliable quality and strong international competitiveness of domestically produced pumping equipment.
