Proper use of the machine
The PFT G 5 SUPER is a continuously operating mixing pump for pre-mixed machinable mortar
with a particle size of up to 3 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 SUPER 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.
