Installation Of A Threaded Pipe Union Pump - salmson SXS Serie Manuel D'installation Et Mise En Service

English
CAUTION! Risk of damage!
Contamination from the pipe system can damage the pump during operation.
Before installing the pump, flush the pipe system.
• Provide shut-off valves upstream and downstream of the pump.
• Attach pipework to the floor, ceiling or wall using appropriate fittings so that
the pump does not bear the weight of the pipework.
• Install the pump at an easily accessible location to allow it to be easily checked
or replaced at a later time.
• Precautions during installation:
• Perform assembly such that the pump shafts are horizontal and not under
strain (see the installation positions shown in Fig. 1). The motor terminal box
must not face downward. If necessary, slacken the socket-head screws and
rotate the motor housing (see chapter 9).
• The direction of flow of the fluid must correspond to the direction of flow
symbol on the pump housing or the pump flange (Fig. 2).

7.1.1 Installation of a threaded pipe union pump

• Install appropriate pipe unions before installing the pump.
• Use the supplied flat gaskets between the suction/pressure ports and pipe
unions when installing the pump.
• Screw union nuts onto the threads of the suction/pressure ports and tighten
them using a suitable open-end wrench or pipe wrench.
CAUTION! Risk of damage!
When tightening the pipe unions, keep the pump in position by gripping the
motor. Not the module/terminal box!
• Check the pipe unions for leaks.
7.1.2 Installation of a flanged pump
Installation of pumps with PN6/10
combination flange (flange-end pumps DN 40 up to DN 65 inclusive)
WARNING! Risk of injury and material damage!
The flange connection can be damaged and develop leaks if the pump is not
installed correctly. There is a risk of injury and damage to property due to hot
fluid escaping.
• Never connect two combination flanges to each other!
• The use of securing elements (e.g. spring rings) can leads to leaks at the
flange connection. They are therefore not permissible. The washers supplied
(Fig. 3, item 1) must be inserted between screw heads/nuts and the combi-
nation flange.
• The permissible tightening torques listed in the table below must not be
exceeded, even if screws of higher strength (
splintering can occur at the edges of the long holes. This causes the screws
to lose their preload and the flange connection can become leaky.
• Use screws of sufficient length. The screw thread must protrude at least one
thread turn beyond the nut (Fig. 3, item 2).
