  • Page 5: Section 1 - General Safety Information

    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.

  • Page 6: Section 2 - Machine Description

    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 electronic drive module contains a variable speed frequency inverter to run a high torque 3-phase gear motor. The inverter unit is rated at 7.5 HP, providing plenty of power to run the MP-25 unit. See the Technical specifications for the input voltage for specific models.
  • Page 30 Fixed to the sides of the control module are a series of polarized plugs, each is color coded to suit the mating socket. Each machine is equipped with a water pump, used as a booster pump to help ensure consistent water pressure, and as such the unit will not run unless the water pressure switch is closed.

  • Page 34: Section 3 - Transportation And Positioning

    Section 3 – Transportation and positioning The machine is typically manually transported around the job site using the two swivel casters at the rear of the machine to steer, with the larger wheels at the front. The machine can be picked up using a forklift, by simply inserting the forks under the base from the rear, and ensuring that they are close enough together to prevent damage to the casters.
  • Page 35 Care must be taken when transporting the machine due to the minimal clearance between the output connector of the pump and the ground. As the unit is “pushed” the pump connector is the furthermost point of the machine and thus prone to damage from impact with objects in front of the machine or from the ground itself.

  • Page 39 Important Safety Instructions: Keep hands clear when swinging the motor into place. Swing the motor assembly into position, checking that the shaft assembles into the slot in the auger drive, and that the location dowels on the motor assembly locate into the pilot holes in the hopper assembly.
  • Page 40 Electrical connections. To be carried out by a licensed / qualified electrician. 1. Ensure that there are no power connections to the Electronic drive module. 2. Site the machine within 50 feet of the power source. 3. Obtain the power cord (supplied with the machine) 3 core for single-phase 220VAC and 4 core for three phase.
  • Page 41 Pre-run setting and test The following must be conducted by a supervisor or a qualified individual experienced in electro-mechanical equipment. Ensure that there are no persons close to the machine. Ensure that there are no obstructions in or around the machine. Turn the speed selection knob to speed 1.

  • Page 42: Section 5 - Machine Operation/Stator Pressure Setting

    1. Connect the pressure tester to the output coupler on the end of the pump unit, with its flow valve OPEN. 2. Fill, up to the lower mixing chamber port of the MP-25 hopper with water using the prime button, and also set the flow meter flow to suit the your material. For this pressure calibration only, add a couple of squirts of a suitable lubricant, such as dish soap.

  • Page 45: Section 6 - Routine Maintenance

    The MP-25 mixing pump unit is very simple to maintain. By far the biggest part of maintenance of the MP-25 machine is cleaning during and after a job. Failure to clean properly after use will damage seals, paint, and moving parts due to material build up causing wear.
  • Page 46 Clean out shaft – using 1. The clean out shaft should only be used in the event that normal cleaning practices do not remove all the material. 2. The clean out shaft can cause significant damage if used incorrectly. 3. The clean out shaft is designed to be used on fresh material, that cannot be removed using normal wash down and manual means.

  • Page 47: Section 7 - Additional Notes

    Section 7 – Additional Notes Wear issues A screw pump can only work reliably if there is adequate and appropriate lubrication. The lubricant produces sliding friction between the rotor and the stator. If this lubricating film is damaged, high temperatures are reached and the elastomer wears within a very short time.
  • Page 48 Start up after extended period of storage Close all pet cocks, reconnect water pipes, close the flow meter, release and close the wash down spray gun. Connect power to the machine, and turn on. Connect a water feed to the water pump inlet Press the water pump switch to turn on the water pump and observe operation.
