Electric Shock & Accidental Starting Hazard
ISOLATE the equipment before any maintenance work is done. Switch
off the mains supply, remove fuses, apply lock-outs where applicable and
affix suitable isolation warning signs to prevent inadvertent reconnection.
7.1
Preparation for Repair/Removal
BEFORE ATTEMPTING ANY REPAIR OR REMOVAL OF A PUMP,
PARTICULARLY IF IT HAS BEEN HANDLING ANY FORM OF
HAZARDOUS LIQUID. ENSURE THAT THE UNIT IS SAFE TO WORK
ON. TO AVOID ANY RISK TO HEALTH IT IS ALSO ADVISABLE TO
WEAR PROTECTIVE CLOTHING AS RECOMMENDED BY THE SITE
SAFETY OFFICER.
7.2
Initial action on discovering a fault.
These pumps contain no user-serviceable parts. If a fault develops contact
SPP Pumps Limited Spares or Service as detailed later.
Please quote the pump Type, Serial No. and Customer Ref. No. detailed on
the SPP Pumps Limited Pump Data Plate.
7.3
To remove the pump unit.
Isolate the electrical power supply and position a warning notice to prevent
the supply being accidentally re-energised.
Remove the terminal box cover, tag the supply cables for later reconnection,
and then disconnect.
Close the pump isolating valves in the pipeline. Drain the oil from the pump
by removing the pump drain plug, if fitted. After draining, refit the plug.
Where no drain is provided on the pump, the oil will need to be drained via
the system drain valves. In this case the pump isolating valves should be
open.
Attach lifting slings to the pump unit as described in Section 2, and carefully
take the weight with the lifting device. Take care not to strain the pipework.
Remove the bolts from the pump/pipe flanges and remove the pump unit
from the system. Immediately fit protection covers to the exposed pump and
pipe flanges. Dispose of old flange gaskets in the correct manner. New
gaskets should always be fitted on re-assembly.
