Build to perform

In the rugged world of under-ground construction, tunnel stabilization, and geotechnical engineering, the demand for performance, precision, and durability is non-negotiable. Enter the RE400NT—a heavy-duty grout mixing and pumping system that has quietly become the backbone of some of the most demanding infrastructure projects across the globe.

The Grouting Gamechanger
The RE 400NT isn’t just a machine—it’s a mission-critical solution for engineers working in environments where reliability is everything. With its robust stainless-steel frame, mixing blade system, and precision water injection control, the 400NT is built to deliver homogeneous, pulsation-free grout under the toughest conditions.

Whether it’s tunnel construction, slope stabilization, or foundation grouting, this pump ensures material consistency and flow rate stability. It’s trusted by professionals worldwide to do one thing extremely well: get the job done, without compromise.

Engineered for Excellence in Demanding Environments
The RE-400NT Grouting Pump is a fully automatic, high-efficiency solution built for a wide range of critical infrastructure projects. From tunnel construction and mining operations to ground engineering, slope stabilization, and general civil engineering applications, this pump delivers unmatched performance under pressure. Its modular design allows for quick dismantling and easy maintenance, while the mixing technology ensures highquality, consistent grout mixtures every time. Designed for continuous operation, it is both robust and user-friendly, making it ideal for tough construction sites. With a 6.2 kW motor, operating at 400V/3-phase/50Hz, and a feed capacity of 6–35 l/min, the RE-400NT maintains a compact footprint and weighs approximately 213 kg—a perfect blend of power, portability, and precision.

Areas of Use

The RE-400NT Grouting Pump is engineered with proven mixing and pumping technology, making it exceptionally suitable for a wide spectrum of specialized construction and geotechnical applications. One of its primary areas of use is injection work, where it delivers high-pressure, pulsation-free grout flow to fill voids, seal cracks, and stabilize structural elements. It is equally effective in re-injection grouting, particularly in complex projects that require multiple grout passes to ensure thorough consolidation of soils or structural reinforcement.

For drill hole filling, the RE-400NT offers precise, controlled grout delivery, making it ideal for sealing boreholes in rock or soil during foundation work, tunneling, or anchoring processes. In backfilling operations, the machine supports efficient material placement behind retaining structures, pipes, or voids, ensuring proper compaction and long-term stability.

Additionally, the pump is highly suited for anchor mortar applications, where accurate, consistent pumping is critical for securing anchor rods and bolts into pre-drilled holes—common in slope stabilization, bridgework, and tunnel construction. The RE-400NT’s ability to perform across these diverse applications underscores its reliability, versatility, and unmatched adaptability in demanding field conditions. It is truly a one-stop solution for modern grouting and injection challenges in civil and underground engineering.
