In a major infrastructure project deep within the Swiss Alps, tunnel engineers faced loose, water-bearing rock that threatened to halt progress. With boreholes stretching beyond 50 meters and grout injection needed under high pressure, the site demanded equipment that combined reliability, remote operability, and rapid clean-up. This is where SupAnchor’s Sup2000 and Sup5000 grout pumps came into play—delivering consistent, high-flow mortar injection to stabilize the ground and keep the project on schedule. As a leading manufacturer of self drilling anchor systems, SupAnchor has once again demonstrated that its pumping technology is engineered for the world’s toughest geotechnical challenges.
Designed to integrate seamlessly with the company’s range of self drilling anchor bolts and hollow bar anchors, the Sup2000 and Sup5000 are high-quality, remote-controlled grout pumps built for injection work, re-injection grouting, drill hole filling, back filling, and anchor mortar placement. Their sturdy construction, epoxy coating, and modular design have already made them a preferred choice across tunnels, mines, and slope stabilization sites in Europe, the Americas, and beyond.
At the heart of the Sup2000 and Sup5000 is a combination of high delivery pressure, wide flow rate ranges, and advanced corrosion protection that directly addresses the biggest pain points in underground construction. The pumps are powered by 400V, 50 Hz electricity supplies—standard across most European and international job sites—and feature remote control capabilities that allow operators to manage grouting from a safe distance, especially critical in hazardous or confined spaces.
The epoxy coating on all exterior surfaces provides optimal corrosion resistance, even when equipment is subjected to abrasive muck, chemical grouts, or frequent jet washings. Moreover, both models can be quickly dismantled without specialized tools, cutting maintenance downtime drastically—a key factor when every hour of tunnel advance matters.

| Delivery Distance | 40 – 60 m | 80 – 120 m |
| Delivery Pressure | 4.0 MPa | 6.0 MPa |
| Electricity Supply | 400V, 50 Hz | |
| Nominal Power | 4.0 KW (pump) | 7.5 KW (pump) + 3.0 KW (mixer) |

| Total Weight | 230 kg | 375 kg |
The Sup2000’s delivery rate of up to 2000 liters per hour makes it ideal for precision work on drill-and-grout bolt installations and soil nail systems, where a steady, metered flow is essential to avoid clogging the narrow hollow bar anchor. Its 4.0 MPa pressure is adequate for most boreholes in competent rock. The larger Sup5000, with a massive 6000 L/h output and 6.0 MPa pressure, instead targets large-scale backfilling and deep anchor mortar placement, where high volume and long pumping distances—up to 120 meters—must be maintained consistently.
From an operational perspective, the difference in nominal power signifies a thoughtful separation of mixing and pumping duties. On the Sup5000, a dedicated 3.0 KW mixer ensures a homogeneous grout suspension before it enters the 7.5 KW pump chamber, preventing segregation and guaranteeing the mechanical properties that self drilling anchor system designs rely on. This integrated mixing station eliminates the need for an external colloidal mixer in many applications, reducing the equipment footprint and simplifying logistics.
SupAnchor’s grout pumps have been validated across a spectrum of geotechnical reinforcement systems. In urban deep excavation support, the Sup2000 is frequently paired with hollow bar anchors to inject precise volumes of cementitious grout behind soldier piles and lagging. Its remote control allows operators to stand clear of the excavation edge while monitoring pressure gauges, enhancing safety on cramped city lots.
In mining, the Sup5000 shines as a backfill pump, delivering tailings mixes over long drifts to stabilize open stopes. The epoxy-coated frame withstands the acidic mine water often encountered underground, a durability feature that directly extends service life and lowers total cost of ownership. At a copper mine in Arizona, U.S.A., project managers reported a 40% reduction in pump-related downtime after switching to the Sup5000, citing its quick-disconnect fittings and smooth rotary action.
Slope stabilization in mountainous terrain presents another ideal use case. Crews installing soil nail systems on steep alpine roads need portable, high-pressure grouting plants that can be moved with a standard pickup truck. The Sup2000’s compact dimensions (1350 × 550 × 850 mm) and 230 kg weight make it transportable without a crane, while its ability to deliver grout at 40 – 60 meters covers common nail lengths. Combined with SupAnchor’s threadbar and drill bit assemblies, it forms a complete drill-and-grout bolt installation chain that eliminates the need for casing in collapsing ground—a distinct advantage in weathered rock formations.
Global infrastructure spending is projected to exceed USD 4 trillion annually by 2025, with tunnel construction and underground space development driving a significant portion of that growth. In this context, the reliability of grouting equipment directly influences project risk profiles. Poor grout injection can lead to ground loss, settlement, and even collapse—risks that contractors and insurers are increasingly unwilling to accept.
The Sup2000 and Sup5000 address these concerns by offering verifiable performance parameters and fail-safe remote operation. They also align with the industry’s shift toward mechanized, less labor-intensive processes. By enabling a single operator to control grout flow from a safe distance, they reduce the need for personnel in high-risk zones and help meet stringent occupational safety regulations like those enforced by OSHA in the U.S. and the EU Machinery Directive.
Moreover, the pumps’ versatility supports a circular construction model. Their easy cleanability and corrosion protection make them suitable for pumping recycled grout mixes and low-carbon binder alternatives that are increasingly specified in green infrastructure projects. As a ground anchor bolt factory with ISO-certified manufacturing processes, SupAnchor ensures that every pump leaving its facility meets consistent quality standards, which is a critical factor for international contractors seeking supply chain reliability.
Founded on principles of professional engineering and collaborative development, SupAnchor has grown into a respected soil nail system manufacturer and a trusted supplier of hollow bar anchor technologies. The company’s R&D team works closely with construction engineers to translate field feedback into product improvements, whether that means refining the pump rotor geometry for longer wear life or adding smart sensors for pressure monitoring.
All SupAnchor grout pumps are backed by the organization’s global distribution network and technical support, spanning Europe, North America, South America, and Southeast Asia. With a portfolio that includes self drilling anchor systems, micro piles, and geotechnical accessories, the company is positioned as a one-stop partner for ground engineering solutions.
As infrastructure networks age and climate resilience becomes a priority, the demand for robust, adaptable ground support technologies will only intensify. The Sup2000 and Sup5000 grout pumps exemplify how a focused, innovation-driven approach can turn a standard auxiliary piece of equipment into a decisive factor in project success. By enabling precise, efficient, and safe grouting, they reinforce not just the rock and soil but the reputation of the engineers who rely on them.
