Installation and operating instructions SIL 425

• Never stand underneath a suspended load.
• Make sure the pump is securely positioned and is stable during
storage and transport as well as prior to all installation and other
assembly work.
DANGER! Risk of burns or freezing to the pump when body parts
come into contact with the pump!
Depending on the pump or system operating conditions (fluid tem-
perature), the entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• In the case of high water temperatures and system pressures, allow
the pump to cool down before all work.
• Always wear protective clothing, protective gloves and protective
goggles when working.
DANGER! Danger of death!
The tools used during maintenance work on the motor shaft can be
flung out if they come into contact with rotating parts, and cause
serious or even fatal injuries.
• The tools used during maintenance work must be removed com-
pletely before the pump is started up.
9.1
Air supply
The air supply to the motor housing must be checked at regular inter-
vals. In case of contamination, ensure that an air supply is re-estab-
lished in order to allow the both the motor and the module to cool
sufficiently.
9.2
Maintenance work
DANGER! Danger of death!
Falling pumps or pump parts may result in life-threatening injuries.
• When performing installation work, protect the pump components
against falling.
DANGER! Danger of death!
There is a mortal danger through shock when working on electrical
equipment.
• Check for absence of voltage and cover or cordon off adjacent live
parts.
9.2.1
On-going maintenance
Maintenance work should always be done with the seals removed.
9.2.2
Replacing the mechanical seal
The mechanical seal is maintenance free. During the running-in
period, a minor amount of dripping is to be expected. A visual inspec-
tion should be performed from time to time, however. If there is
clearly detectable leakage, the seal must be changed. Salmson offers
a repair kit which contains the necessary parts for replacement.
Dismantling
Dismantling:
• Disconnect the system from the power supply and secure it against
being switched on again.
• Make sure it is not live.
• Earth and short-circuit the working area.
• Close the check valves in front of and behind the pump.
• Disconnect the power cable.
• Depressurise the pump by opening the vent screw (Fig. 1, Item 2).
DANGER! Risk of scalding!
Due to high fluid temperatures there is a risk of scalding.
• At high fluid temperatures, let the pump cool down before starting
any work.
• Dismantle the coupling protection metal sheets (Fig. 1, Item 1).
