Section 1 -General Safety information
Danger
Follow these instructions very carefully, in order to avoid injury to yourself or others.
Electrically powered machine.
Always ensure that all power to the machine has been turned off and isolated before
ANY maintenance / repair work is carried out on the machine.
Ensure that all guards are correctly fitted before starting or attempting to operate the
machine.
Ensure that all fasteners are present and correctly fitted before attempting to start or
operate the machine.
Ensure that the pump unit is correctly fastened to the front of the hopper unit of the
machine, and free of damage before attempting to start or operate the machine.
Ensure that the main electric drive motor assembly, are secured to the rear of the hopper
and clamped in place and free from damage before attempting to start or operate the
machine.
The MP-25 mixing pump unit can produce high pressures, high torques and can use high
voltages. Care must be taken by all users. Only authorized and trained persons should
work with this machine.

Section 2 -Machine Description
Function
The MP-25 is a mixing pump.
The machine has a drive motor, that turns a drive shaft within a material hopper that in
turn feeds material through a mixing / hydration chamber to a progressive cavity rotor
stator pump unit that delivers the material from the hopper to the dispense head or
otherwise via a material hose / hoses.
The machine is driven by an electric motor powered by 220VAC 3 phase 50/60Hz, via
an electronic variable speed inverter supplied by two phase (commonly called single
phase) OR three phase 208/240VAC 50/60 Hz grounded electrical supply.
All styles of drives transmit their rotary action through a drive shaft equipped with bridge
breakers, and metering flights, which convey the material from the hopper into the
mixing / hydration chamber, where surface hardened mixing arms mix and shear the
material with water, towards the pump unit, where further mixing occurs.
The pump unit is a progressive cavity pump unit comprising of a helical rotating “rotor”
with the rubber lined “stator”. As the rotor rotates, material is drawn / fed into open
rubber cavities, which then transform into “pockets”. The series of cavities, then move
from one end of the stator to the other as the rotor turn with respect to the stationary
stator, causing the material to be conveyed from the hopper towards the outlet.
Once the material has reached the outlet it is guided through an output flange assembly,
into the dispense hose through to the hose outlet, where typically a spray nozzle is
attached allowing, with the assistance of an auxiliary air supply, the material to be
“sprayed” on to the substrate, or simply allowed to discharge from the end of the hose.
A number of different devices can be fitted to the outlet of the tube for different means of
application. For details of these different devices please contact your supplier of
Machine-Technologies equipment or Machine-Technologies directly.
The primary difference between the three models is the combination of, rotor stator size
(D or R style), water flow meter capacity (4 GPM or 7 GPM), and motor HP (5.4 or 7.5).
