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.

3 Phase gear motor. The inverter unit is rated at 7.5 HP providing plenty of power to run the MP-25 unit. The module is supplied with an input plug allowing immediate wiring into your own 220VAC 2 phase or 3 Phase (as applicable depending up on the model) supply (Must be carried out by an approved installer).

Single-phase drive module The Single-phase drive module, in addition to the previously mentioned items is equipped with an inverter error signal light, which illuminates if the inverter goes into overload for example. The three phase unit has a phase detection module with prevents the power from coming on unless the phases are wired to run the unit in the correct direction.
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.

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 pint of the machine and thus prone to damage from impact with objects in front of the machine or from the ground itself.
Section 4 – Machine set up Unpacking Remove the safety grid from the top of the machine by removing the 4 bolts, clips and washers, using the provided 7/16” AF wrench . Keep all parts to be used to replace the grid later.
Machine assembly Ensure that the drive shaft is fully engaged in the rotor at the pumping end of the machine. It is essential that the round center guide be in the pilot hole of the rotor and that the lower spar be in the slot. Page 32...

Rotate the motor output shaft and auger drive by hand, or a suitable lever until the flat end of the mixing shaft aligns with the slot in the end of the hauling bracket on the motor. Page 33...

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. It maybe necessary to swing with some momentum to enable full closure, if the either the motor or the pump have recently moved position.
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 3 phase.
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.
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.

Ideal set up method, to be amended to suit your actual application The rotor stator pump is a positive displacement, progressive cavity pump, the positive displacement aspect being controlled by the clamping tension on the stator. 1. Adjust the stator to have minimal tension. 2.
General notes for operation • Grease auger drive seal daily, with water resistant, corrosion inhibited grease. • For starting the pump, Ensure that the speed control is at selection 1. • Turn main power switch on. • Prime the mixing chamber with water. •...
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.
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 from the job. 2. The clean out shaft can cause significant damage if used incorrectly. 3.
Section 7 – Notes on wear of rotor stator pump unit Wear issues Dry running of a rotor-stator pump 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.
LIMITED WARRANTY POLICY Machine Technologies warrants each of its new machines to be free of defects in material and workmanship under normal use and services for a period of one (1) year from the date of delivery. The warranty is issued ONLY to the INITIAL USER. The warranty period begins when the product is delivered to the initial user or when first put into service, whichever occurs first.
