5.3 Installation of Pipes
When installing pipes, observe the following notes
to ensure trouble-free function of the pumping
circuit:
•
All elements of the pumping circuit, such as
pipes, shut-off armatures, valves etc., which
come in contact with the medium must be
cleaned carefully. Inside the lines, seals must
not protrude toward the interior, to prevent
contaminants from reaching the interior of the
pump and causing damage or destroying the
pump.
•
Use only pipes or hoses which are suitable for
the operating pressure of the respective pump,
the prevailing temperatures and the media to
be pumped.
•
The lines must be connected so that no force
is transmitted to the pump (unconstrained
connection). Therefore it is recommended to
install the pressure lines to the pump before it
is fastened to the container cover.
•
The flow of the medium in the lines should not
be obstructed by sharp bents, edge valves and
return flaps. Unavoidable reductions of the
line's cross-section must be softened by
sloping transitions. Sudden changes of the
flow direction must be avoided in any case.
•
The lines must be seal tight and installed in
such a way that air may not be shut in at any
point.
•
The pipes should always be laid out rising. It
should be possible to vent pressure lines at the
highest spot.
•
The cross-section of the pressure line should
at least reach the cross-section of the
pressure connection.
5.4 Connection of Pipes
The pipes are connected to the pressure housing of
the pump at the connection provided. Ensure that
no force is transmitted to the pump.
Connect the pipe with a flat face end seal and a
cylindrical thread. If tapered threads are used, a
suitable sealing material must be used.
The screw-in torque should not exceed 70 Nm,
since the pump connector may otherwise burst or
break off.
5.5 Fastening to the Container
Once the pressure line has been installed, the
pump can be fastened to the container at a
maximum tightening torque of 15 Nm.
