SupAnchor, a leading manufacturer of self drilling anchor systems, self drilling anchor bolts, and hollow bar anchors, has announced the global rollout of its SupPump SDA grout pump series, comprising the Sup2000 and Sup5000 models. Designed to complement the company’s geotechnical reinforcement system portfolio, these pumps address the critical need for reliable, high-pressure grouting in tunnel construction, mining, civil engineering, and slope stabilization. The launch follows extensive field validation and reflects SupAnchor’s commitment to delivering integrated drill-and-grout solutions that enhance safety and productivity on demanding job sites.
On a typical tunnel or slope stabilization project, self drilling anchor bolts are installed using rotary percussion drilling, which simultaneously creates the borehole and advances the anchor. Once the specified depth is reached, grout is injected through the hollow bar to bond the anchor with the surrounding ground. The quality of this grouting operation directly affects the load-bearing capacity and long-term durability of the geotechnical reinforcement system. The SupPump SDA series is engineered to deliver consistent, controlled grout flow under high pressure, ensuring complete filling of the borehole and surrounding fissures.
Key features of the SupPump SDA grout pumps include:
The technical specifications of the two models highlight their adaptability to different project scales. The table below summarizes the key parameters:
| Parameter | Sup2000 | Sup5000 |
|---|---|---|
| Delivery rate | 40–2000 liters/hour | 6000 liters/hour |
| Delivery distance | 40–60 meters | 80–120 meters |
| 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) | 1350×550×850 mm | 1485×600×850 mm |
| Total weight | 230.00 kg | 375.00 kg |
The Sup2000 offers a delivery rate adjustable from 40 to 2000 liters per hour, making it ideal for fine injection work and re-injection grouting in fractured rock or loose soil. Its delivery pressure of 4.0 MPa and distance of 40 to 60 meters allow effective grouting without excessive equipment relocation. For larger-scale operations, the Sup5000 mortar mixing grout pump delivers up to 6000 liters per hour at 6.0 MPa, with a delivery distance of 80 to 120 meters, catering to high-volume anchor mortar and back filling tasks. Both models operate on a standard 400V, 50 Hz supply, simplifying site logistics. The compact dimensions facilitate transportation and positioning in confined tunnel environments, while the total weights of 230 kg and 375 kg respectively provide stability without sacrificing mobility. The epoxy coating on the frame protects against corrosion from cementitious grouts and abrasive site conditions, ensuring long service life.
The remote control capability is especially beneficial in hazardous environments such as tunnel headings or high walls, where the operator can remain at a safe distance while monitoring pressure and flow. This reduces exposure to falling debris, grout splatter, and confined space risks. The quick-clean design further supports productivity by allowing crews to flush the system rapidly between shifts or when switching from cement-based to chemical grouts.
The versatility of the SupPump SDA series makes it a valuable asset across multiple sectors. In tunneling, the pumps are used for drill hole filling and contact grouting behind initial linings, where controlled injection pressure prevents ground settlement. In mining, they support rock bolt installation and cavity filling, improving ground control in high-stress environments. For slope and hillside shoring, the pumps enable efficient anchor mortar placement, securing soil nail systems and self drilling anchor bolts in unstable terrain.
From a market perspective, the integration of a reliable grout pump with a self drilling anchor system reduces the number of equipment interfaces and minimizes downtime. Contractors in Europe and North America increasingly demand complete geotechnical reinforcement systems that can be deployed rapidly with minimal training. The SupPump SDA series, with its remote control and quick-clean design, addresses these operational priorities, allowing crews to focus on core drilling and anchoring tasks. Moreover, the wide delivery rate range on the Sup2000 permits precise injection in delicate urban environments, while the high-volume Sup5000 meets the demands of large-diameter anchor installations in major infrastructure projects.
In tunnel projects crossing fault zones or water-bearing strata, the ability to perform re-injection grouting at high pressure is crucial to control water ingress and stabilize the excavation face. The Sup2000’s variable delivery rate allows operators to start with a low flow to avoid blowouts in weak ground, gradually increasing as the formation accepts grout. The Sup5000, with its higher pressure and integrated mixing, is particularly suited for back filling large cavities or for systematic anchor mortar placement in long tunnels where logistical efficiency is paramount.
The pumps also contribute to geotechnical safety by ensuring that grout completely fills the annular space around hollow bar anchors. Voids or incomplete grouting can lead to anchor failure and ground movement, posing risks to workers and adjacent structures. By maintaining consistent pressure and flow, the SupPump SDA series helps achieve the design bond strength required for long-term stability.
SupAnchor has built its reputation as a soil nail system manufacturer and ground anchor bolt factory by investing in R&D and maintaining rigorous quality standards. The company’s self drilling anchor systems are manufactured in China and exported to projects worldwide, backed by ISO certifications and a track record of performance in complex geological conditions. The introduction of the SupPump SDA grout pump reinforces this commitment, providing a cohesive solution that spans from hollow bar anchor drilling to final grouting.
The pump's epoxy-coated frame and robust components reflect an understanding of the harsh handling conditions often encountered on construction sites. SupAnchor’s engineering team has focused on user-friendly maintenance: the pump can be dismantled quickly, and all parts exposed to grout are designed for fast cleaning, which is critical when switching between cementitious and chemical grouts. This practical innovation aligns with the brand message of being professional, innovative, and collaborative—working closely with contractors to refine equipment based on real-world feedback.
As global infrastructure investment accelerates, the need for reliable geotechnical reinforcement systems continues to grow. The SupPump SDA grout pump Sup2000 and Sup5000 represent a timely addition to SupAnchor’s portfolio, offering contractors a robust, high-performance tool for a wide range of grouting applications. With proven technology and adaptability, these pumps are expected to become a standard choice for tunnel and mining projects seeking efficiency, safety, and long-term ground stability.
