We recently received an inquiry from a client in Oman for drilling grouting equipment. They sought an integrated unit combining a grout mixer, an agitator/storage tank, and a plunger pump, with a maximum pressure requirement of 60 kg/cm². The client required a system capable of handling grout preparation, storage, agitation, and injection to meet the demands of on-site drilling and grouting operations.

Based on the client's application and pressure requirements, we recommended a suitable grouting station model and outlined the equipment's workflow, configuration features, and on-site setup. This solution integrates mixing, storage, and pumping into a single unit, facilitating efficient construction organization and equipment management. The client expressed great satisfaction with the suitability of the recommended model and the proposed solution.

The configuration of this grout mixer, agitator, and plunger pump unit was designed with a focus on grout uniformity and the continuity of grout supply during the drilling and grouting process. After the mixer blends the cement, water, and appropriate additives, the grout is transferred to the agitator/storage tank. Continuous agitation in the storage tank minimizes sedimentation while the grout awaits pumping, ensuring the material entering the plunger pump remains relatively homogeneous. Simultaneously, the mixer can prepare the next batch of grout, ensuring a steady supply for subsequent injection and reducing downtime associated with batch-by-batch preparation.

For drilling and grouting applications, the pump must not only possess the necessary pressure capability but also deliver an appropriate flow rate at the target pressure. The client's requirement for a maximum pressure of 60 kg/cm² served as a key criterion for equipment selection. In practical application, operating parameters—such as flow rate and pressure—must be matched to factors including the grout mix ratio, borehole depth, pipeline length, and formation grout absorption, balancing delivery resistance against downhole injection requirements. Selecting the right plunger pump ensures the prepared grout is effectively delivered to the injection point and allows injection operations to proceed according to the construction methodology.

This grout mixing plant with a plunger pump can be configured for use in projects such as micropiling, soil nailing, ground anchoring, and borehole sealing. In micropile and anchoring operations, a uniform grout mixture is essential for filling borehole voids and ensuring the required contact between the grout and the surrounding medium. Furthermore, properly matching grout mixing and pumping capacities facilitates the timely completion of backfill grouting. Since different applications have varying requirements regarding grout materials, flow rates, and pressures, we recommend equipment based on specific site conditions to ensure the configuration best suits the project.

As a professional supplier of grouting equipment, we offer customized solutions—tailored to mixing capacity, storage volume, pumping performance, and power configuration—to ensure seamless integration with on-site drilling operations.
