Circulation pump
The circulation pump can also be switched on and off in manual ope-
ration. It is important that the pump is vented after filling the liquid in
manual operation so that it has full capacity and that it does not run dry
and possibly become damaged. This is done by switching the pump on
and off several times with the water filled in (until no more air bubbles
escape). In automatic mode, this is done automatically.
In the brewing process and in manual operation, the pump switches off
automatically for protection at 90°C and does not switch on again until
88°C. The speed and thus the performance of the pump can be regulated
via touch control on the display or via the pressure in the line, which is
precisely measured by a pressure sensor. The speed and thus the output
of the pump can be regulated via touch control on the display or via the
pressure in the line, which is precisely measured with a pressure sensor.
Optimum circulation pressure for brewing is just under 0.15-0.2 or
0.1-0.15 bar for the Braumeister 500/ 1,000l (readable on the pressure
gauge or on the control at the top of the display). The circulation can also
be controlled by speed or a set pressure. When using the former variant,
one must pay attention to the pressure during the process itself.
You can access the pump control menu by pressing the P symbol at the
top of the menu bar (see next page).
The pressure of 0.2 bar or 0.15 bar must not be significantly exceeded
to avoid overpressure in the malt pipe. The pump capacity is limited to
approx. 0.25 bar for the 200l or 0.2 bar for the 500/ 1,000l.
