h.
Pump shaft must be rotated freely by hand.
i.
Adjust the impeller clearance if necessary.
j.

of pump & motor bearings.
2.
Start-Up
a.
Open the isolation valve in suction pipe.
b.
Make sure suction pipe is properly primed upon opening of the gate valve.
c.
Check the rotation by jump start the motor. Rotation should be same to direction of arrow
reflected in pump volute.
d.
Start the driver.
e.
Slowly open the isolation valve in discharge pipe.
f.
Do not operate the pump exceeding to its rated working pressure.
g.
Use calibrated tester or current meter instrument to check if actual current of motor is within
the normal range.
h.
Observe the pump volute. If high temperature is observe, immediately shut down the pump
and inspect the pump and suction pipe.
i.
Observe pump vibration if it is within the normal range.
j.
Mechanical Seal
i.
Excessive temperature & vibration could damage the ceramic coating of
mechanical seal.
ii.
Presence of solid particles in water could also damage the mechanical seal.
iii.
Misalignment of pump and/or motor shaft could also damage the mechanical
seal.
k.
Packing Seal
i.
Adjust packing gland nut if excessive water is observe during operation.
ii.
Apply more packing if water leak is excessive.
g.
Adjust all necessary protective electrical components in control panel for motor protection.
h.
