Brief description
2019-12-11 17
9 Brief description
The new compact mixing pump RITMO XL with 400V AC drive, developed especially
for pumping, spraying and coating of machine-operated dry mortars, materials and
many more items up to 3mm grain size.
Depending on the requirement, the pumping capacity can be adjusted through a
quick pump change. The pneumatic filling is guaranteed via an optional injection
hood in conjunction with a hopper.
The machine consists of portable single components that permit a quick and
comfortable transportation for convenient dimensions and low weight.
10 Material
10.1 Flowability / conveying property
NOTE:
The D6-3 pump can be used at up to 30 bar operating pressure.
The possible conveying distance depends essentially on the flow properties of the
material.
Fluids, priming materials, colors etc. have good flow properties.
The material hose lengths must be shortened if the operating pressure exceeds 30
bar.
To
avoid machine faults, increased wear and tear of the pump motor, pump shaft and
pump, please use original PFT spare parts only such as:
PFT rotors
PFT stators
PFT pump shafts
PFT material hoses.
These are made for each other and form a constructive unit with the machine.
Non-observation will not only make the warranty null and void, the user must also
contend with mortar of bad quality.
11 Mortar pressure manometer
Caution!
The use of a mortar pressure manometer is
recommended for technical safety reasons.
Fig. 22: Mortar pressure manometer
PFT mortar pressure manometer
Some advantages of the mortar pressure manometer:
Exact regulation of the correct mortar consistency.
Constant check of the correct pumping pressure.
Early detection of a blockade or overloading of the pump motor.
Creation of pressure release.
Serves to a large extent to safeguard the operators.
Long life span of the PFT pump components.

12 Safety rules
Caution!
Please observe the regional safety rules for mortar
pumping while performing all jobs!
13 Transport, packing and storage
13.1 Safety instructions for transport
Improper transport
CAUTION!
Damages due to improper transport!
Improper transportation can lead to
considerable material damages.
– Exercise caution while unloading the
packed components as well as during in-
house transportation, and observe the
symbols and instructions on the package.
– Use only the provided lifting positions.
– Remove the packages only just before
installation.
Floating loads
WARNING!
Danger to life from floating loads!
While lifting loads, falling or uncontrolled
swiveling components pose danger to life.
– Never stand under unstable loads.
– Observe the specifications of the provided
tying points.
– Do not lift loads at projecting machine
components or components attached to
lugs, and ensure a stable base of the tying
resources.
– Use only approved lifting devices and tying-
resources having adequate supporting
capacity.
– Do not use torn or damaged ropes and
belts.
– Do not place ropes and belts on sharp
edges and corners, do not tie knots and do
not turn.

13.2 Transport inspection
Immediately after receipt, check to ensure that the delivery
is complete and free of transport damages.
Proceed as follows if there are externally identifiable
transportation damages:
Do not accept delivery or accept delivery only under
reservation.
Mention the scope of damage on the transport
documents or on the delivery receipt of the transport
agency.
NOTE:
Complain about each defect as soon as it is
detected. Damage claims can be filed only
within the valid complaint periods.
13.3 Transport in single parts
Fig. 23 : Open rotation lock
Fig. 24 : Mixing pump unit
1. For easier transportation, dismantle
the machine into its individual parts.
2. Detach the units mixing tube with
material container and pump, geared
motor with tilt flange and
undercarriage.
3. Detach cable- and hose connections.
Open the rotation lock (Fig. 23:).
Remove the mixing tube with material
container from the undercarriage.

13.4 Transportation with crane
Fig. 25: Crane transportation
Observe the following conditions:
Crane and lifting devices must be designed to support the
weight of the packages.
The operator must be authorized to operate the crane.
Remove all loose parts (1) in the machine.
Tying:
1. Tie ropes or belts at all 4 crane lugs (2).
2. Ensure that the package is suspended straight, if
necessary, observe eccentric center of gravity.
