The pump is delivered with a mounting plate.
The mounting plate can be mounted vertically
e. g. on a wall or horizontally e. g. on a tank. It takes

the mounting plate by means of a slot mechanism.
The pump can easily be released from the mounting
plate for maintenance.

not vibrate.
• Dosing must flow upwards vertically.
4.1.2 Align and install mounting plate
