FOREWORD
Dear MAI customer!
We wish to congratulate you on your purchase of
the MAI m400NT mortar mixing pump. The MAI
pump m400NT is a fully automatic mortar mixing
pump for continuous processing of all kinds of ma-
chine-processable anchor mortar and building site
cement.
The pump is driven by one motor only. A rubber
screw in the mixer transports the dry anchor mortar
to the mixing chamber where it is continually mixed
with water.
The water can either be supplied direct if the pres-
sure is high enough or an optional water pump can
be fitted, if required.
Once the material is thoroughly mixed, the entire
amount is then drawn in and pumped away by the
clampless, maintenance-free screw pump.
The most important features of the MAI pump
m400NT are the high quality of the components
used, the user-friendly layout of the controls and the
rugged design which proves its worth, day in and
day out on demanding building site applications.
User-friendly
o Simple to service and dismantle thanks to the
modular design.
o Clearly structured operating elements.
o Economical.
o The patented MAI mixing and pumping tech-
nology guarantees continuous blending of dry
material, uniform mixing ratio, constant mixing
quality and therefore adequate processing.
