User-friendly injection systems: you can rely on the legendary MAI®400NT Cement grouting pumps are an integral part of major engineering and construction projects worldwide. The MAI®400NT is the global number one for grouting and injection work. It has proved its worth over several decades on mining, tunnel and underground jobsites. The MAI®400NT needs little introduction for those in the construction and ground engineering industries. This grout pump features proven technology for a long service life, whatever conditions you throw at it. It provides constant mixture proportions for grouting and backfilling applications, thereby ensuring the right kind of processing and perfect results every time. You can expect excellent material mixing due to the patented water injection and mixing tools (Patent No. WO 2004/080676 A1 and Patent No. EP 1 768 771 B1). Innovative mixing and conveying technology has put the MAI®400NT grout pump at the top of its field for injection work, subsequent mortar grouting, filling drilled holes, and backfilling excavation work. Robust grouting machines for reliability The MAI®400NT is designed to give users peace of mind. The robust design, using highly wear-resistant MAI®CODUR stainless steel and hot-dip galvanised components, guarantees corrosion protection in the roughest grouting conditions. It is able to adapt quickly to varied geological situations because it has been specifically developed to withstand extreme stresses underground.
