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 space
disc (item no. 20 10 19 00) can be installed for coarse plaster.
Mortar pressure
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:
¾ Exact regulation of correct mortar consistency
¾ Constant monitoring of the correct conveying pressure
¾ Early detection of clogging or overloading of pump motor
¾ Establishment of zero pressure
¾ Significant contribution to the safety of the operating personnel
¾ Durability of the pump components
PFT pump components
Warning!
During installation/removal of the mortar pump, the following must be
observed:
The main switch must be switched off during assembly!
NOTE:
¾ New pump components with a conveying hose of 10 m should attain a conveying pressure of
approx. 30 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:
¾ A new rotor and new stator need to be run in; actual pressure values can only be determined
after the first spraying cycle.
¾ Pump components which neither attain the required conveying pressure nor maintain the
required backpressure are worn out and must be replaced.
