4.2 Transport and Storage
● 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 Observe permissible storing temperature!
4.3 Mounting
● Mount the pump horizontally on the tank or on a console.
4.4 Connecting the Suction and Pressure Lines
!
WARNING All lines must be stress-free!
Only use the prescribed line types!
● 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 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.
