applicable.
WARNING
WARNINGWARNING
MOVING PARTS HAZARD
Moving parts can pinch, cut or amputate fingers and other body parts.
•Keep clear of moving parts.
•Do not operate equipment with protective guards or covers removed.
•Pressurized equipment can start without warning. Before checking, moving, or servicing equip-
ment, Relieve Pressure and disconnect all power sources.
ELECTRIC SHOCK HAZARD
This equipment must be grounded.Improper grounding, setup, or usage of the system can cause
electric shock.
•Turn off and disconnect power before servicing equipment.
•Connect only to grounded electrical outlets.
•Ensure ground prongs are intact.

regulations.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
•Do not operate the unit when fatigued or under the influence of drugs or alcohol.
•Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component.
•Use fluids and solvents that are compatible with equipment wetted parts. Read fluid and solvent
manufacturer’s warnings. For complete information about your material, request Safety Data
Sheet (SDS) from distributor or retailer.
•Turn off all equipment and Relieve Pressure when equipment is not in use.
•Check equipment daily. Repair or replace worn or damaged parts immediately with genuine man-
ufacturer’s replacement parts only.
•Do not alter or modify equipment. Alterations or modifications may void agency approvals and cre-
ate safety hazards.
•Make sure all equipment is rated and approved for the environment in which you are using it.
•Use equipment only for its intended purpose. Call your distributor for information.
•Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
•Do not kink or over bend hoses or use hoses to pull equipment.
•Keep children and animals away from work area.
•Comply with all applicable safety regulations.

Warnings
PRESSURIZED EQUIPMENT HAZARD
Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause
serious injury.
• Relieve Pressure when you stop spraying/dispensing and before cleaning, checking, or servicing
equipment.
•Tighten all fluid connections before operating the equipment.
•Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, includ-
ing eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes but is
not limited to:
•Protective eyewear, and hearing protection.
•Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufac-
turer.

Section 1 - General Safety information
Warning
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, is secured to the rear of the hopper,
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 three phase 50/60Hz,
via an electronic variable speed inverter supplied by single phase OR three phase 220-
240, or 350-415 VAC 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 a metered supply of water is combined with the
material. In the mixing / hydration chamber is 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 pockets, 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 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).
