20.3 Water from a water barrel
Fig. 30: Booster pump

Booster pump AV3000 (1) item number 00130205
The booster pump which is connected ensures the required water
pressure of minimum 2.5 bar.
NOTE!
When working with water from the barrel, the inlet
strainer must be fitted with a filter strainer (item no.
00136619) (bleed booster pump).
21 Setting the water factor
21.1 Presetting the water flow rate

Fig. 32: Water outlet valve
To adjust the expected water volume at the needle valve (1):
1. Close the needle valve.
2. Then open the needle valve by two rotations.
3. The water flow rate totals approx. 200 l/h in this position.
4. The consistency of the material can be adjusted using the
needle valve.
NOTE!
Turning the needle valve clockwise reduces the
water flow rate, while turning it anti-clockwise
increases the water flow rate, making the material
more viscous or more fluid.
Observe the specifications of the material
manufacturer.
NOTE!
Every interruption to the mixing process causes a
slight irregularity in the consistency of the
material. This irregularity will normalise itself as
soon as the machine has been operating for a
short period.
It is therefore unnecessary to change the water
flow rate with each irregularity. Wait until the
consistency of the material has returned to
normal.
