3.3 Installation mécanique
The pump range includes both flanged and threaded versions.
These installation and operating instructions apply to both versions,
but give a general description of flanged versions. If the versions
differ, the threaded version will be described separately.
Install the pump so that it is not stressed by the pipes. For
maximum permissible forces and moments for pipe connections
acting on the pump flanges or threaded connections, see MAGNA3
(Appendix).
You can suspend the pump directly in the pipes, provided that the
pipes support the pump.
Twin-head pumps are prepared for installation on a mounting
bracket or base plate. The pump housing has a M12 thread.
Step Action
Arrows on the pump housing
indicate the flow direction
through the pump. The flow
1
direction can be horizontal
or vertical, depending on the
control box position.
Close the isolating valves
and make sure that the sys-
2 tem is not pressurised dur-
ing the installation of the
pump.
Mount the pump with gas-
3
kets in the pipes.
