The end of the suction line (3) has to be equipped with a suction
strainer with filter screen and built-in non-return valve.
We recommend an additional filter for fine particles in the suction
line.
NOTE!
The flow rate of the pump decreases with
increasing length of the suction line. Connect the
booster pump as close as possible to the water
sampling point (pressure is better than suction).
If all these points have been observed the pump can be switched
on. Depending on the length of the suction line, the suction time
can be up to a few seconds. If the pump does not deliver after
some minutes, this might be due to the following reasons:
There is still air in the pump and it has to be vented completely
once again.
The suction line has a leak and the pump draws air.
The suction strainer is clogged.
There is a kink in the suction hose.
The maximum suction height is exceeded.
Caution!
The pump must not run dry to avoid any damage.
The dry section to accommodate the ready-mixed mortar is
separated from the mixing and pumping section. The dry mortar it
thrown into the mixing chamber via the inclined star wheel. The
PFT G 4 X can be started and refilled at any time. The star wheel
is powered separately and can be quickly disassembled using a
central locking mechanism.
