A TWISTER D5-2.5 or D6-3 pump system belongs to the standard
equipment of the PFT G 54 E mixer pump.
The rotor and stator are subject to wear and must be checked regularly.
WARNING!
A mortar pressure gauge must be used in compliance with the accident
prevention regulations of the Builders’ Guild.
Mortar pressure gauge
The PFT mortar pressure gauge is used to monitor the mortar consistency
quickly and easily.
The mortar pressure gauge is part of the scope of delivery.
Some advantages of the mortar pressure gauge:
¾
Constant monitoring of the correct conveying pressure
¾
Early detection of clogging or overloading of the pump motor
¾
Establishment of zero pressure
¾
Significant contribution to the safety of the operating personnel
¾
Durability of the pump components
WARNING!
Make sure the main switch is switched off during the installation when
installing/removing the mortar pump.
NOTE:
Furthermore, observe that:
¾
A new rotor and new stator need to be run in; real pressure values can
only be determined after the first spraying cycle.
¾
Pump components which do not achieve the specified operating pressure
(15 bar) are worn out and must be replaced.
¾
With a conveying hose of 10 m, new pump components should attain a
conveying pressure of approx. 25 or 30 bar and maintain a back pressure
of approx. 2/3 of the conveying pressure from the screw pump before
and after the first spraying cycle.
¾
We recommend using the PFT pressure tester with coupling and outlet
tap (item no. 20 21 68 10) to monitor the back pressure.
