► Install a shut-off valve in the discharge line.
► Design the suction lines to be as short as possible.
►
Install the suction lines in horizontal position or at a constant dropping angle towards
the pump unit. Rule out the possibility of air pockets and dips in the pipes.
► Lay and connect the pipes to ensure that no stresses are applied to the connections.
►
Secure pipes to ceilings, walls, or floor using pipe clamps.
► Align pipes flush with pump connections using a bracket.
6.6 Supply System Connection
The following connections are standardly provided on the suction and discharge sides in
DIN 11851 (milk pipe):
6.7 Hydraulic Connection
The hydraulic connection is adapted to machine size, project specifications, or customer re-
quirements (see order confirmation).
6.7.1 Suction-Side Connection
A slight pre-pressure is required on the suction side to ensure free inflow of the base medi-
um into the powder mixer. The hydrostatic pressure from the supply tank at a pressure of
approx. 0.05–0.5 bar (0.5–5.0 m suction head) is optimal here.
► If required, use only a controlled pump on the suction side. It will not affect the suction
behavior of the powder mixer and will prevent fluid from being forced into the funnel.
6.7.2 Discharge-Side Connection
The back pressure from the powder mixer to the supply tank must be minimized. For this
reason, the discharge line cross section must be as large and the line length as short as pos-
sible. The standard version of the powder mixer can generate a maximum back pressure of
0.5–0.6 bar for optimum powder draw-in.
►
If additional components, e.g., heat exchangers or filters, that generate a significant pres-
sure loss are added to the circuit, the operator should install an additional pump down-
stream of the discharge-side connection on the powder mixer.
