Installing A Threaded Pipe Union Pump; Installating A Flanged Pump - salmson SIRIUX Série Manuel D'installation Et Mise En Service

• Precautions during installation:
• Perform assembly so that the pump shaft is horizontal and not under strain
(see the installation positions shown in Fig. 2a/2b).
• Make sure that it is possible to install the pump with the correct flow direction
(cf. Fig. 2a/2b). Observe the direction triangle on the pump housing (Fig. 1a;
item 2).
• Make sure that it is possible to install the pump in the permitted installation
position (cf. Fig. 2a/2b). If required, turn the motor including control module,
see Chapter 9.1.

7.1.1 Installing a threaded pipe union pump

• Install appropriate threaded pipe unions before installing the pump.
• Use the supplied flat gaskets between the suction/pressure ports and threaded
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 to property!
Do not hold the pump by the motor/module when tightening the screwed
connections. Apply the wrench surfaces to the suction/pressure port
instead.
Pump type
Siriux 25-30(40, 60, 65)
Siriux 32-30(40, 60, 65)
Siriux 32-90
• Check the threaded pipe unions for leaks.

7.1.2 Installating a flanged pump

Installation of pumps with combination flange PN6/10 (flange-end pumps from
DN32 up to and including DN 65) and flange-end pumps DN80.
WARNING! Risk of injury and damage to property!
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!
• Pumps with combination flanges are not suitable for operating pressures
PN16.
• The use of securing elements (e.g. spring rings) can result in leaks at the
flange connection. They are therefore not permitted. The washers supplied
(Fig. 3, item 1) must be inserted between screw heads / nut heads and the
combination flange.
