Proper use of the machine
The PFT G 5 c FU is a continuously operating mixing pump for pre-mixed machinable mortar with
a particle size of up to 2 mm.
Please observe the processing guidelines of the material manufacturer!
The machine consists of portable individual components of handy dimensions that allow fast,
convenient transport.
The following points should be observed during operation:
1) Connection for worksite distribution board – control box
2) Connection for control box – pump motor
3) Connection for control box – compressor
4) Connection for compressor – air manifold
5) Connection for water supply – water manifold / booster pump
6) Connection for air manifold – air hose
7) Connection for air hose – finishing plaster device
8) Connection for mixing tube – mortar pressure gauge
9) Connection for mortar pressure gauge – mortar hose
10) Connection for mortar hose – finishing plaster device
Description of functions
The PFT G 5 c FU can be loaded with bagged materials or by means of a delivery hood or injection
hood. The mixing shaft and the pump are driven by a geared motor. The pump motor speed is
approximately 400 rpm. Water is added and mixed into the dry material in the mixing area. The water
flow rate needs to be set manually at the needle valve. The water flow rate may be checked using the
water flow meter. A pressure switch monitors the water flow pressure. If it falls below 1.9 bar, the
machine shuts down automatically. This problem is prevented by installing a booster pump upstream.
The mixed mortar is pumped away by a screw pump installed downstream from the mixing shaft.
A spraying gun can be mounted at the end of the conveying hose. The compressed air required for
spraying is supplied by a compressor.

Air nozzle tube clearance
The distance between the air nozzle tube and plaster nozzle should always be
equivalent to the diameter of the plaster nozzle hole;
for example: 14 mm finishing plaster nozzle = 14 mm distance.
Direction of rotation of the star wheel motor
The star wheel usually works independently of the direction of rotation. If a SILOMAT
conveying system is being used, we recommend a clockwise direction of rotation
(factory setting). This ensures that the pump motor also runs in the correct direction.
Star wheel
Gap, star wheel to hopper floor: factory setting approx. 8 mm
Rule of thumb:
1.5 x diameter of largest dry mortar particle. If required, star wheel spacer disc
(item no. 20 10 19 00) can be installed for coarse plaster.

Mortar pump D6-2L
The mixer pump PFT G 5 c FU is standardly equipped with the pump system D6-2L.
The rotor and stator are subject to wear and must be checked regularly.
WARNING!
The use of a mortar pressure gauge is absolutely imperative according to the safety
regulations of the Builder’s Guild.
PFT mortar pressure gauges monitor the mortar consistency efficiently and easily.
Some benefits of the mortar pressure gauge:
Exact regulation of correct mortar consistency
Constant monitoring of the correct conveying pressure
Early detection of clogging or overloading of pump motor
Establishment of zero pressure
Significant contribution to the safety of the operating personnel
Durability of the pump components
PFT pump components
New pump components with a conveying hose of 10 m should attain a conveying
pressure of approx. 15 bar and maintain a back pressure of approx. 2/3, before and
after the first spraying. We recommend using the PFT pressure tester with coupling
and outlet tap to monitor the backpressure
(item no. 20 21 68 10).
During installation/removal of the mortar pump, the following must be observed:
- the main switch must be switched off during assembly.
Furthermore, observe that:
A
new rotor and new stator need to be run in; actual pressure values can only be
determined after the first spraying cycle.
Pump components which neither attain the required conveying pressure nor maintain
the required backpressure are worn out and must be replaced.
Checking the conveying pressure and backpressure
Connect the 10 m conveying hose
Connect the pressure tester to the outlet tap at the hose end
Open valve
Switch on machine and let water run until water emerges from the outlet tap (let hose
bleed)
Close valve
Let pump run against pressure until there is no more increase in pressure
Switch off the machine
If the required pressure is no longer attained, the maintenance-free pump must be
replaced
Check the backpressure
A backpressure of approx. 2/3 of the conveying pressure of the screw pump should
now be maintained in the hose

PFT G 5 c FU 230V Operating Manual Issued: 09.2007
Knauf PFT GmbH & Co. KG
19
NOTE!
1. A D6-2L stator can be used up to 15 bar operating pressure.
2. The maximum conveying distance depends mainly on how a particular type morta
r
flows. Heavy, coarse-grained mortar does not flow well. Fluid mortars, filling
compounds and floor screed have good flow characteristics.
3. Using thicker mortar hoses is recommended if you exceed an operating pressure o
f
15 bar.
4. Use the following original spare parts to avoid machine malfunctions and excessive
wear on the pump motor, pump shaft and pump:
PFT rotors
PFT stators
PFT pump shafts
PFT mortar pressure hoses
PFT clamps
These components are compatible with one another and form a single constructive
unit together with the machine. If you do not follow these recommendations, you will
not only lose your warranty rights, but the quality of the mortar will also suffer.
Start-up
- Transport assemblies as near as possible to the object to work with
(for the assembly, see Transport).
- Lock the castor before putting the machine into service.
Clean and bleed the 3/4" water hose to clean out impurities.
Then connect the water hose to the built-in water pump.
Note
Only use clean water that is free of particulates. The minimum pressure is 2.5 ba
r
when the machine is running.
WARNING!
When working from the water drum, the strainer with filter screen
(item no. 20 47 50 00) must be mounted (bleed water pump).

PFT G 5 c FU 230V Operating Manual Issued: 09.2007

The machine may only be connected to a worksite distribution board with 16 A and
approved 30 mA FI safety switch. The connection cable must correspond to the
H07 RN-F 3 x 2.5 mm² version.
We always recommend using the 3 x 2.5 mm², 25 m PFT power cable with safety plug
and CEE coupling (item no. 20 42 34 20).
Before the control box is connected to the power supply, the following steps must be
performed:
-
Turn off the main reversing switch (1) (“0” position, lockable).
-
Turn the star wheel switch (2) to “0”.
-
Pull out the dummy plug (3).
Connect pump motor (10-pin plug).
Switch off the compressor. (Pull the plug)
Connect the control box to the power supply.
Now the following steps must be carried out:
Turn on the main switch
