Product Introduction

Concrete Injection Devices are electric hydraulic pumping systems designed for conveying cement mortar, fine concrete, and grout with aggregates up to 8 mm. They provide stable high-pressure injection for crack repair, void filling, anchoring, tunnel grouting, and structural reinforcement in construction and infrastructure projects.

Key Features

10 MPa pumping pressure provides stable material delivery for long-distance and high-resistance grouting applications.
Double pump & double-circuit hydraulic system improves pumping stability and reduces pressure fluctuations during continuous operation.
37 kW electric motor delivers consistent power with lower maintenance than diesel-driven alternatives.
Wired and wireless remote control allows operators to manage pumping safely from a convenient working position.
Air-cooled hydraulic system helps maintain stable operating temperature during extended construction periods.

Typical Applications

Building Foundation Grouting – Injects cement-based materials to fill voids and improve foundation stability.
