6.8 Pipework connection

If a tool, e.g. a chain pipe wrench, is used when the
riser pipe is fitted to the pump, the pump must only
be gripped by the pump discharge chamber.
When connecting plastic pipes, a compression
coupling should be used between the pump and the
first pipe section.
For pumps fitted with plastic pipes, the
expansion of the pipes when loaded
should be taken into consideration, when
deciding on the installation depth of the
pump.
Where flanged pipes are used, the flanges should
be slotted to take the submersible drop cable.
Figure 11 shows a pump installation with indication
of:
• position of cable clips, pos. 1, and distance
between the clips.
• fitting of straining wire, pos. 2.
• maximum installation depth below the static
water level.

6.8.1 Cable clips

Cable clips must be fitted every 3 metres.
See fig. 11.
When connecting plastic pipes, some slackness
must be left between each cable clip as plastic pipes
expand when loaded.
Where flanged pipes are used, the cable clips
should be fitted above and below each joint.
