8.4 Riser pipe
WARNING
Sharp element
Death or serious personal injury
‐
If a tool, for example a chain pipe wrench, is used when the riser
pipe is fitted to the pump, the pump must only be gripped by the
pump outlet chamber.
The threaded joints on the riser pipe must all be well cut and fit
together to ensure that they do not work loose when subjected to
torque reaction caused by the starting and stopping of the pump.
The thread on the first section of the riser pipe, which is to be
screwed into the pump, must not be longer than the threads in the
A
pump.
Plastic pipes are recommended for 4" pumps only.
Max 0.3m
When plastic pipes are used, secure the pump by an unloaded
straining wire to be fastened to the outlet chamber of the pump. See
fig. Fixing the straining wire.
Fixing the straining wire
When connecting plastic pipes, use a compression coupling
between the pump and the first pipe section.
From 6" to 10" there is no hook or connection eye for straining wire.
When flanged pipes are used, the flanges must be slotted to take
the submersible drop cable and a water indicator hose, if fitted.
