A shut-off valve should be installed in the feed
line. It must be closed for maintenance work.
It should be installed in order to avoid air pockets
forming in the spindle cap, i.e. with the spindle in
a horizontal position or pointing vertically
downward.
3.1.2 Discharge line
For flow regulation, a valve must be installed
behind the pump. If non-return valves are used,
they should close smoothly. Pressure shocks
must be avoided.
3.1.3 Inlet and outlet connections
The various connecting points are shows in the
drawings. (See Annex, Chapter 10, point 10.1).
3.1.4 Pressure control
For consistent control of pressure, it is advisable
to install in the pipework a measuring point in front
of, and behind the pump.
3.2 Electrical connections
For the drive motor a mains connection is required
which complies with the European Regulations
and Directives for the Standards in Industry and
with the instructions of the local power supply
utilities of the country concerned.
