Installation, Operation and Maintenance (IOM) Manual
b.
Floor of pump room or storage should be dry, free from any stagnant water for avoid certain
accidents.
c.
No moisture or humidity exists inside the pump room or storage. Necessary ventilation system
is required.
d.
Pump room or storage must be secured, free from any thieves and trespassers. Only
authorized personnel or maintenance should have an access inside.
e.
Shut down all power supply when performing maintenance routine to avoid certain accidents.
f.
Wear Personal Protective Gear or Equipment before performing maintenance check.
g.
It is highly recommended to update regularly the maintenance record for future reference.
2.
Bearings
a.
Bearings are not allowed to operate higher than 70
o
C. Inspect the bearings if temperature is
not within the normal ranges.
b.
Lubricate bearings using calcium based grease or SAE20W Oil. Pumps in 2 pole speed
(2900rpm in 50hz or 3500rpm in 60hz) should replenish oil or grease every 2500 working
hours. 4 pole speed (1450rpm in 50hz or 1750rpm in 60hz) should replenish oil or grease
every 5000 working hours. Do not over lubricate because it will cause to overheat.
c.
Bearings should be replaced every 10000 working hours.
3.
Mechanical Seal
a.
Presence of high temperature in pump volute, excessive vibration and poor quality of water
will damage the ceramic coating of mechanical seal.
b.
Mechanical seals should be replaced immediately if leakage found during standby and running
operation.
4.
Packing Gland Seal
a.
There should be water droplet in packing gland seal during in running operation. Standard
drop ranges from 50 to 70 droplets in every minute.
b.
Adjust packing gland cover by adjusting the bolts if water droplets is exceeded in standard
ranges.
c.
Packing gland is consumable or subject for wear & tear depending on operation. Replace the
packing gland if water droplet exceeded to its standard ranges even though packing gland
cover has been adjusted accordingly.
5.
Electrical Conditions
a.
Power voltage fluctuations
i.
To maintain the expected life period, do not operate the electric motor if
1.
Actual voltage fluctuates beyond tolerance bands of +/- 10% from normal
power voltage.
2.
Actual voltage fluctuates within tolerance bands of +/- 10% from normal
power voltage for more than 60 minutes each day.
ii.
Electric components for protection against abnormal fluctuation of power supply
voltage or to maintain the stability of power supply voltage for entire day is required
to avoid premature damage of electric motor.
