In challenging geological conditions—whether deep in tunnels, along precarious slopes, or within active mining environments—the reliability of grouting equipment can make or break a project. SupAnchor’s new SDA grout pumps, the Sup2000 and Sup5000, are purpose-built to deliver consistent, high-pressure injection for a wide range of geotechnical applications. As part of a comprehensive geotechnical reinforcement system, these pumps ensure seamless integration with self drilling anchor bolts, hollow bar anchors, and other drill-and-grout bolt technologies.
From tunnel construction to slope stabilization, the Sup2000 and Sup5000 have already proven their value on projects worldwide. Their remote-controlled operation, robust epoxy coating, and rapid disassembly for cleaning set them apart as go-to solutions for contractors who demand efficiency and durability.
The Sup2000 and Sup5000 are not just pumps; they are integral components of a modern geotechnical reinforcement system. Engineers specify these units for their precise control over grout flow and pressure, which is critical when working with self drilling anchor systems. The table below summarizes key technical parameters that directly impact site productivity and safety.

|---|---|---|
| Delivery Rate (l/h) | 40 – 2000 | 6000 |
| Delivery Distance (m) | 40 – 60 | 80 – 120 |
| Delivery Pressure (MPa) | 4.0 | 6.0 |
| Electricity Supply | 400 V, 50 Hz | 400 V, 50 Hz |
| Nominal Power (kW) | 4.0 | 7.5 (grout pump) + 3.0 (mixer) |
| Dimensions L×W×H (mm) | 1350 × 550 × 850 | 1485 × 600 × 850 |
| Total Weight (kg) | 230 | 375 |
The delivery rates and distances directly address the logistical challenges of large-scale projects. For example, the Sup5000’s 6000 l/h output and 120 m distance reduce the need for frequent repositioning, saving time in tunnel boring operations. The 6.0 MPa pressure ensures that grout penetrates even dense geological formations, making it ideal for ground anchor bolt installations in fractured rock. The Sup2000, with its variable rate, excels in precision tasks like re-injection grouting and anchor mortar filling.
The Sup5000’s integrated mixer is a standout feature for projects requiring continuous grout supply. The 3.0 kW mixing unit keeps grout in suspension, preventing sedimentation and ensuring a consistent mix throughout the pumping cycle. This is particularly valuable when using heavy or quick-setting grouts, which are common in geotechnical reinforcement systems where early strength is critical. For the Sup2000, the variable delivery rate allows operators to fine-tune grout flow from a mere 40 liters per hour for delicate crack injection up to 2000 l/h for bulk backfilling, making it one of the most versatile pumps in its class.
Another key advantage is the electrical design. Both pumps run on a standard 400 V, 50 Hz supply, which is widely available on European and many international sites, eliminating the need for costly transformers or generators. The motors are rated IP55, providing protection against dust and water jets, further enhancing site suitability. The epoxy coating on the frame and components has been tested in salt-spray chambers, proving its durability in coastal or highly corrosive environments, such as mines with acidic water.
Both pumps feature a sturdy construction with an epoxy coating that provides exceptional corrosion resistance, even under harsh handling conditions. The design allows for easy dismantling, rapid cleaning, and maintenance—essential for projects with tight schedules. The remote control capability enhances operator safety, especially in hazardous environments such as active mine faces or unstable slopes.
SupAnchor’s SDA grout pumps have been deployed in a variety of demanding settings. In tunnel construction, whether for transportation or hydropower, the Sup5000 often serves as the primary pump for backfilling behind tunnel linings, while the Sup2000 handles precise drill hole filling for rock bolts. In mining, where ground support is critical, these pumps work alongside self drilling anchor bolts to consolidate loose strata, mitigating risks of collapse. For slope stabilization and hillside retention, they deliver anchor mortar for soil nail systems—a process where a reliable grout supply is paramount.
Additionally, in civil engineering projects such as building excavations, the pumps are used for injection work to create cutoff walls or for re-injection grouting to enhance soil strength. The versatility of the Sup2000 and Sup5000 makes them a preferred choice for contractors who require a single equipment line to cover multiple geotechnical reinforcement tasks. As a leading soil nail system manufacturer and ground anchor bolt factory, SupAnchor ensures that its pumps are fully compatible with its extensive range of hollow bar anchors and drill-and-grout bolts.
The remote-controlled operation is a game-changer for job sites where minimizing human exposure to hazards is a priority. Operators can control the pump from a safe distance, reducing the risk of accidents during high-pressure grouting. This feature, combined with the pumps’ quiet electric motors, aligns with modern European and North American safety standards.
In urban metro construction, space constraints often limit the size and mobility of equipment. The Sup2000’s compact dimensions (1350 × 550 × 850 mm) and relatively low weight of 230 kg mean it can be maneuvered into tight station boxes and cross-passages. Its quiet operation is an additional benefit in noise-sensitive city-center projects. Meanwhile, the Sup5000, although larger, can be positioned at a distance thanks to its 120-meter delivery range, minimizing disruption to the worksite.
For slope stabilization, the pumps work with self drilling anchor bars to create composite reinforcement structures. The anchor mortar must fill the full length of the borehole and bond with the steel bar and surrounding soil or rock. The Sup2000’s precise pressure control prevents hydrofracturing in weak soils, while the Sup5000’s high output accommodates large anchor arrays on expansive slopes. This reliability has made SupAnchor a preferred supplier for ground anchor bolt installations in regions prone to landslides, from the Andes to the Himalayas.
The global push for sustainable infrastructure and the expansion of underground construction are driving demand for efficient grouting solutions. SupAnchor’s SDA grout pumps address a critical need: delivering consistent, high-volume grout with precision, even in the most challenging geological conditions. By integrating these pumps into a self drilling anchor system, project managers can streamline operations, reducing labor costs and material waste.
The Sup2000 and Sup5000 have already made a mark in international markets. On a recent motorway tunnel project in the Alps, the Sup5000’s 120-meter delivery distance enabled a single-pump setup for an entire tunnel section, whereas traditional pumps required multiple relay stations. In an Australian iron ore mine, the Sup2000’s variable flow rate was instrumental in executing delicate grout injections behind tunnel segments, ensuring long-term stability without over-pressurization. Such case studies highlight the pumps’ adaptability to diverse geological and climatic conditions.
From a business perspective, the pumps offer a compelling value proposition: they reduce downtime through easy maintenance, cut energy consumption thanks to efficient motors, and extend service life with superior corrosion protection. For rental companies and large contractors, the quick-clean design translates to higher equipment utilization rates. As infrastructure investments surge in North America and Europe under new government programs, the demand for reliable geotechnical reinforcement systems like SupAnchor’s is set to grow.
The global geotechnical services market is projected to grow at over 5% annually, fueled by urbanization and aging infrastructure.
