In the rugged terrain of the Swiss Alps, a major railway tunnel project recently faced the challenge of installing permanent ground anchors through fractured granite and high groundwater inflows. The contractor needed a grouting pump that could deliver precise volumes of cement grout at pressures high enough to fill every fissure around the drill-and-grout bolts, yet remain portable enough to move along the tunnel face. SupAnchor supplied its SupPump SDA grout pump series—the Sup2000 and Sup5000—to meet these exacting demands. The pumps' performance on this project exemplified why they have become a preferred choice for tunnel construction, civil engineering, mining, and slope stabilization worldwide.
SupAnchor, known globally for manufacturing self drilling anchor systems, self drilling anchor bars, and hollow bar anchors, designed the SupPump series to complement its anchor products. The Sup2000 and Sup5000 provide the necessary grouting capacity for a wide range of geotechnical reinforcement applications, including injection work, re-injection grouting, drill hole filling, back filling, and anchor mortar placement. Their remote-controlled operation and sturdy, epoxy-coated construction ensure reliability under the harshest site conditions.
For geotechnical engineers, precise control over grout delivery is essential. The Sup2000 grout pump offers a delivery rate ranging from 40 to 2000 liters per hour, while the Sup5000 mortar mixing grout pump achieves an impressive 6000 liters per hour. This flexibility allows contractors to match the pump to project scale—from small-scale anchor installations to large-volume backfill operations. Delivery distance is another critical factor. The Sup2000 can transport materials over 40 to 60 meters, sufficient for most tunnel and slope applications. The Sup5000 extends this to 80 to 120 meters, enabling long-distance grouting without intermediate pumping stations. Delivery pressures of 4.0 MPa and 6.0 MPa respectively ensure that grout penetrates deep into drill holes and voids, achieving full encapsulation of self drilling anchor bolts and hollow bar anchors.

|---|---|---|
| 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 (grout pump) + 3.0 KW (mixer) |
| Dimensions (L×W×H) | 1350×550×850 mm | 1485×600×850 mm |
| Total weight | 230.00 KG | 375.00 KG |
The sturdy construction of both models includes an epoxy coating that provides optimal corrosion protection, ensuring longevity even under the harshest handling conditions on construction sites. Operators benefit from easy dismantling and quick cleaning and maintenance, reducing downtime between grouting cycles. Remote controlled operation enhances safety by allowing personnel to manage the pump from a distance, particularly in hazardous tunnel or slope environments.
The SupPump series is engineered to complement SupAnchor's full range of geotechnical reinforcement systems. In drill-and-grout bolt installations, the Sup2000 provides precise low-to-medium flow rates ideal for filling hollow bar anchors with grout. For larger projects requiring substantial backfill or re-injection work, the Sup5000's high delivery rate and integrated mortar mixing capability reduce labor and time.
These capabilities make the SupPump series suitable for a wide array of projects, from urban deep excavations to remote mountain slope stabilization. The ability to switch between low and high flow rates using the Sup2000 and Sup5000 respectively provides contractors with a tailored solution for each phase of construction.
As global infrastructure spending continues to rise, the demand for reliable grouting equipment in tunneling and mining sectors grows in parallel. Projects such as metro systems, highway tunnels, and hydroelectric power plants require continuous grouting operations under challenging conditions. The SupPump series addresses these needs with robust design, corrosion resistance, and remote operation, reducing maintenance costs and improving worker safety.
In the mining industry, where equipment must endure abrasive materials and frequent relocation, the compact dimensions and manageable weight of the Sup2000 (230 kg) and Sup5000 (375 kg) allow for easy transport within underground workings. The 400V, 50 Hz electrical supply is standard across European and many international sites, ensuring compatibility without additional transformers.
For geotechnical safety, the precise control of grout pressure and flow rate is essential to achieve the design bond strength of a self drilling anchor system. Inadequate grouting can lead to premature anchor failure and slope instability. The SupPump series, with its proven mixing technology, helps ensure that every hollow bar anchor is fully grouted, enhancing the overall reliability of the reinforcement.
SupAnchor has established itself as a trusted soil nail system manufacturer and ground anchor bolt factory, exporting self drilling anchor systems, self drilling anchor bars, self drilling anchor bolts, and self drilling hollow bars worldwide. The company's commitment to research and development is evident in the engineering behind the SupPump series.
