In major urban tunnelling and deep excavation projects across Europe and North America, contractors continually face difficult ground conditions—loose soils, fractured rock, and high groundwater pressures. Effective ground reinforcement requires not only robust self drilling anchor systems but also dependable grouting equipment capable of injecting cementitious or chemical grouts at controlled pressures and flow rates. SupAnchor, a leading soil nail system manufacturer and ground anchor bolt factory based in China, addresses this need with its SupPump SDA grout pump range, comprising the Sup2000 and Sup5000 models. These pumps have been successfully applied worldwide in tunnel construction, civil engineering, mining, and shoring for building excavations, slopes, and hillsides, providing proven mixing and pumping technology for injection work, re-injection grouting, drill hole filling, back filling, and anchor mortar.
The SupPump SDA series is designed specifically for the demanding requirements of self drilling anchor bolt installation and geotechnical reinforcement system applications. Contractors who deploy hollow bar anchors and drill-and-grout bolts need a grout pump that can match the penetration rate of the drilling rig while maintaining consistent pressure and material quality. The Sup2000 and Sup5000 deliver exactly that, with delivery rates ranging from 40 to 2000 liters per hour for the Sup2000 and up to 6000 liters per hour for the Sup5000 mortar mixing grout pump. These capacities enable high-productivity grouting in both small-diameter anchor boreholes and large-volume backfill operations, making the pumps essential assets for complex infrastructure projects.
Understanding the technical specifications of the SupPump SDA grout pumps is essential for evaluating their suitability for a given project. The tables below summarize the key performance data for the Sup2000 and Sup5000 models.
| Parameter | Sup2000 Grout Pump | Sup5000 Mortar Mixing Grout Pump |
|---|---|---|
| Delivery rate | 40 – 2000 L/h | 6000 L/h |
| Delivery distance | 40 – 60 m | 80 – 120 m |
| Delivery pressure | 4.0 MPa | 6.0 MPa |
| Electricity supply | 400V, 50 Hz | 400V, 50 Hz |
| Nominal power | 4.0 kW | 7.5 kW (pump) + 3.0 kW (mixer) |
| Dimensions (L×W×H) | 1350mm × 550mm × 850mm | 1485mm × 600mm × 850mm |
| Total weight | 230.00 kg | 375.00 kg |
The delivery pressure of 4.0 MPa for the Sup2000 is sufficient for most soil nail and hollow bar anchor grouting tasks, while the Sup5000's 6.0 MPa capability enables longer-distance and higher-resistance applications, such as deep re-injection grouting or back filling behind tunnel linings. The electric supply of 400V, 50 Hz aligns with standard European site power systems, minimizing the need for transformers or frequency converters. The nominal power ratings—4.0 kW for the Sup2000 and 7.5 kW plus 3.0 kW for the Sup5000—ensure efficient energy use without sacrificing performance. The dimensions and weights allow for transport in standard site containers and positioning in confined gallery spaces.
SupAnchor's grout pumps feature sturdy construction and an epoxy coating that provides optimal corrosion protection, enabling them to withstand the harshest handling conditions on active construction sites. They are designed for easy dismantling, quick cleaning, and low maintenance, reducing downtime and extending service life. The remote controlled grouting pump functionality enhances operator safety by allowing control from a distance, particularly important in tunnel faces or unstable slope areas. These productivity characteristics are summarized below.
The SupPump SDA grout pump range is not limited to a single application. Its proven mixing and pumping technology is suitable for injection work, re-injection grouting, drill hole filling, back filling, and anchor mortar placement. In self drilling anchor system installations, the pump must synchronize with the drilling process to inject grout through the hollow bar as the anchor advances. This drill-and-grout method requires a pump that can maintain a steady flow even under variable backpressure from the ground. The Sup2000's delivery rate range from 40 to 2000 liters per hour allows precise control for low-volume grout injection in sensitive ground, while the Sup5000's higher output supports large-scale backfill operations behind retaining walls or tunnel arches.
For geotechnical reinforcement systems, especially in mining and tunnelling, the ability to deliver grout over distances of 40 to 60 meters (Sup2000) or 80 to 120 meters (Sup5000) means the pump can be positioned in a safe, accessible location while grouting remote boreholes. This reduces the need to move equipment frequently and improves overall site logistics. The remote control feature further supports operations in hazardous areas, such as tunnel headings or steep slopes, where direct operator presence would be risky.
In addition, the Sup5000 mortar mixing grout pump integrates a mixing unit, enabling continuous preparation of grout on site. This is particularly valuable for projects using cement-based grouts, where maintaining slurry consistency is critical for achieving the required bond strength of self drilling anchor bolts. The epoxy-coated steel frame resists damage from abrasive materials and rough handling, ensuring long-term reliability in demanding environments. Such adaptability makes the SupPump SDA series a preferred choice for contractors working with hollow bar anchors and soil nail systems in complex geologies.
As infrastructure investment accelerates in Europe and North America, the demand for reliable ground anchor bolt factory products and geotechnical reinforcement systems continues to grow. Urban tunnelling projects, metro expansions, deep foundation excavations, and slope stabilization works require efficient grouting equipment that can keep pace with modern drilling rigs. The SupPump SDA series addresses these needs by offering a balance of delivery rate, pressure, and portability. Contractors benefit from reduced grout waste, improved quality control, and enhanced safety—all of which contribute to lower project costs and shorter schedules. In an industry where time and precision are paramount, the Sup2000 and Sup5000 deliver measurable value.
SupAnchor's commitment to research and development is evident in the design of the SupPump SDA grout pumps. The company's self drilling anchor systems, including self drilling anchor bars, self drilling anchor bolts, and hollow bars, are manufactured under strict quality management systems. SupAnchor holds ISO certifications that attest to its production processes and product consistency.
