DANGER
Excessive temperature rise in the shaft seal area in the event of a defective
containment shroud
Explosion hazard!
Leakage of hot or toxic fluid handled!
▷ Monitor for leakage (fit monitoring equipment).
▷
If fluid leakage is detected as a result of a defective containment shroud, make
sure that the pump set is switched off as quickly as possible.
Leakage barrier shaft seal
ring
The leakage barrier ensured by a shaft seal ring has been designed for the following
operating limits:
▪ Max. permissible fluid temperature: 100 °C
▪ Max. permissible pressure = 16 bar
▪
Max. permissible operating period with a defective containment shroud (leakage
barrier subjected to pressure load during pump operation): 1 hour
NOTE
For low inlet pressures and low heads, KSB recommends that leakage be monitored
by means of a level transmitter (Liquiphant). In the case of higher inlet pressures
and heads, containment shroud leakage can also be monitored by means of a
pressure gauge.
6.3 Shutdown/storage/preservation
6.3.1 Measures to be taken for shutdown
The pump (set) remains installed
ü Sufficient fluid is supplied for the functional check run of the pump.
1. For prolonged shutdown periods, start up the pump (set) regularly between
once a month and once every three months for approximately five minutes.
ð This will prevent the formation of deposits within the pump and the pump
intake area.
The pump (set) is removed from the pipe and stored
ü The pump has been properly drained. ( ð Section 7.3, Page 50)
ü
The safety instructions for dismantling the pump have been observed.
1. Spray-coat the inside wall of the pump casing and, in particular, the impeller
clearance areas with a preservative.
2. Spray the preservative through the suction nozzle and discharge nozzle.
It is advisable to then close the pump nozzles (e.g. with plastic caps).
3. Oil or grease all exposed machined parts and surfaces of the pump (with
silicone-free oil or grease, food-approved if required) to protect them against
corrosion.
Observe the additional instructions on preservation. (
ð
Section 3.3, Page 14)
If the pump set is to be stored temporarily, only preserve the wetted components
made of low-alloy materials. Commercially available preservatives can be used for
this purpose. Observe the manufacturer's instructions for application/removal.
6.4 Returning to service
For returning the equipment to service observe the sections on commissioning/start-
up and the operating limits. (
ð Section 6.1, Page 31) ( ð Section 6.2, Page 39)
In addition, carry out all servicing/maintenance operations before returning the
pump (set) to service. (
