technical specifications, diagrams etc. are subject to copyright law. All rights, errors and
modifications are reserved.
Initial inspection after delivery:
An important task of all technicians delivering the PFT G 5 c FU is the inspection of the machine
settings at the end of the first work phase. The factory settings may change during the initial cycle.
If these changes are not corrected in time, immediately after run-in, problems may arise during
operation.
Following receipt of the PFT G 5 c FU mixer pump and training in regard to it, i.e. after about two
hours of operation, the technician must always carry out the following checks / make the following
settings:
1) Water pressure switch
2) Pump pressure, backpressure
3) Air pressure switch
4) Pressure reducer

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.
