8.1.1 Activation
Installation and operating instructions SIL, PBS (with cartridge mechanical seal)
• Wear protective clothing, protective gloves and protective
goggles.
NOTE:
It is recommended to have the pump serviced and checked by
Salmson customer service.
The pump has to reach ambient temperature before commissioning.
• Check whether the shaft can be rotated without any grinding. In case
the impeller is blocked or grinds, loosen the coupling screws and
tighten them with the specified torque (see list "Table 5: Screw tight-
ening torques" on page 58).
• Prime and vent the unit correctly.
WARNING! Danger due to extremely hot or extremely cold
pressurised fluid!
Depending on the temperature of the fluid and the system pres-
sure, when the venting screw is opened completely, extremely hot
or extremely cold fluid in liquid or vapour may escape or shoot out
at high pressure.
• Always exercise caution when opening the venting screw.
CAUTION! Risk of property damage!
Running dry will destroy the mechanical seal.
• Make sure that the pump does not run dry.
• To avoid cavitation noises and damage, a minimum inlet pressure
2
must be guaranteed at the suction port of the pump. This minimum
inlet pressure depends on the operation situation and the duty point
of the pump, and must be defined accordingly.
The main parameters for defining the minimum inlet pressure are the
NPSH of the pump at its duty point and the vapour pressure of the
fluid.
• By briefly switching on, check whether the direction of rotation
agrees with the arrow on the fan cover (see Fig. 47, item 2). If the
direction of rotation is incorrect, proceed as follows:
• For direct starting: Swap 2 phases on the motor terminal board
(e.g. L1 for phase L2).
• For Y-Δ start, swap the winding start and winding end of 2 windings
on the motor terminal board (e.g. V1 for V2 and W1 for W2).
• The unit may only be switched on when the shut-off device on the
pressure side is closed! Only after full speed has been reached may
this be slowly opened and be adjusted to the duty point.
• The unit must run smoothly and free of vibration.
• The mechanical seal ensures that a seal will not leak and requires no
special setting. Should there be a small leakage at the beginning, it
will stop when the initial inlet phase of the gasket is over.
• Immediately after the conclusion of all work, all the provided safety
and protection equipment items must be properly installed and put
into operation.
DANGER! Risk of fatal injury!
Failure to install safety devices on the terminal box or near the
coupling can cause electrical shock or contact with rotating parts,
potentially resulting in life-threatening injuries.
