Handle with care, do not throw!
Dry and cool storage place.
Take heed of upright position of the dosing pump when storing it, so that
gear grease can not leak out.
CAUTION
Mount the pump horizontally on the tank or on a console.
WARNING
!
Depending on the material of the connection flanges (1) (mating flanges)
•
Pipe and flange made of 1.4571 steel:
Weld the pipe in the blanking flange
•
Pipe and flange made of PP:
Weld the pipe in the flange sleeve
•
Pipe and flange made of PVC:
Adhere the pipe in the flange sleeve
The internal diameter of the lines, adapters and connectors should not be
smaller than DN 65; if necessary, use bends instead of elbows.
The suction lines must be designed such that cavitation is avoided.
IMPORTANT:
Pulsation dampers should be fitted on both the suction and pressure
sides.
NOTE
Observe permissible storing temperature!
All lines must be stress-free!
Only use the prescribed line types!
A positive pressure difference of 10 m water gauge is
required for correct operation of the dosing pump. If the
total of the back-pressure and the static difference in
height between the suction valve and the dosing point is
less than 10 m water gauge, a pressure maintenance
valve must be installed directly upstream of the dosing
point.
