Grout pump for all your industrial injection systems needs

The MAI®440GE grout pump for all your industrial injection systems needs

The dual mixing principle of the MAI®440GE guarantees top mixing quality and allows variable programmes for the injection system, making it suitable for almost every application.

Developed by professionals for professionals

The MAI®440GE grout pump is the result of decades of experience and has been developed by professionals for professionals. MAI has taken existing injection systems to the next level, with the goal of developing a high-performance grout pump that sets new standards in process security.

The patented mixing blades guarantee a homogeneous mixing and processing quality (patent No: EP 1 768 771 B1). Constant monitoring information and the easy-to-see multilingual operating status on the display screen ensures simple operation and high process reliability.

In particular, by adding the MAI®LOG400 data logging and data monitoring equipment to the system you can capture information such as pressure, injected volume, consumed water and time, making construction site billing very straightforward. You can even micro-bill while drilling is ongoing!

Saving time, money, and the environment

Compared to standard injection systems, the MAI®440GE is a real time saver. This grouting machine makes flow rates from 5 to 60 litres per minute possible at operating pressures of max. 45 bar and hose lengths up to 100m. At the same time, it is very easy to operate.

The system allows permanent visual control of the mix quality in the wet mortar area, making readjustment possible at any time. There is no settling or hardening of the mixed material as the agitator constantly mixes the material during work breaks and keeps it moving. The injection process and continuous mixing means no waiting periods and reduced errors, saving you time and money. The simplified cleaning process leads to waste reduction, lower disposal costs and higher machine efficiency.

The MAI®440GE grout pump is also designed to be sustainable due to the use of stainless steel components, a galvanised frame and wear resistant MAI®Codur synthetic components.
