EXTERNAL DAMAGE, LOOSE PARTS
Make sure that all screws, bolts and nuts are tight.
Check the condition of the pump lifting handle and
replace if damaged or worn. Replace any external part
that appears worn or damaged.
MOTOR INSULATION RESISTANCE
Use a 500 V DC Megger and measure the insulation
between the phases and between any phase and
ground. Resistance values should be over 1 M ohm. If
abnormal readings are obtained, immediately hand
the pump in for repair.
Also observe any local requirement regulations. The
stricter one will prevail.
OIL
Check the condition of the oil to see if any water
leakage has occurred. Remove the oil plug (3). Take
an oil sample using a pipette. Check for impurities
and emulsification. (Oil must be clear.) If water
intrusion has occurred the seal must be replaced.
Refill the seal chamber with fresh oil. Refer to section
Technical details for type and quantity of oil.
IMPELLER
Inspect the impeller by removing the strainer and
wear plate. Replace the impeller if it is damaged or
severely worn.
POWER CABLE
Inspect the cable for cuts, scrapes or sharp bends. If
the outer jacket is damaged, replace the cable. Do not
make splices within wet wells.
CABLE ENTRY
Make sure that the cable entry flange and strain relief
clamp are tight. If the cable entry is showing signs of
leakage replace the cable.
